Pi audio changed behavior - Vol Up Down is not working #973

htpzc · 2020-05-22T19:24:34Z

Bug

Volume Up and Down brings error

What I did

Fresh Install with Master Branch.
No Spotify.
Hold it simple
GPIO Buttons are default configured.
All other buttons work fine (forward, back, play/pause)

What happened

Everything works fine, but vol up down buttons dont work

I expected this to happen

vol turns up and down

Further information that might help

In all other installations before with and without Spotify the buttons worked fine!

Branch / Release

s-martin · 2020-05-24T12:03:49Z

Are you using the spotify edition or the classic edition?

We released 2.0 just moments ago, this release should fix many, many issues, so you could give that a try.

topas-rec · 2020-05-29T22:15:03Z

I updated my packages in apt. Afterwards my volume buttons also don't work anymore.
I reinstalled Phoniebox software through the buster script without success. (Regarding volume control)
I have the same errors in system log. (With slightly different line numbers. My error is in line 238 of playout controls and slightly different unexpected argument errors. My unexpected argument is '3' and a parenthesis - like above)

Changing the volume in the web app also does not work.

How can I debug this?

Manually changing PCM in alsamixer of course works.

topas-rec · 2020-05-29T22:16:05Z

I can try to make a clean install tomorrow.
Otherwise I'll have to roll back my sdcard backup image from before the update.

Hi
i'm playing around with a new installation of version 2 on a raspbery pi 3. unfortunately i can't get my already successfully used rotary encoders to work.

installation on Buster lite led to several "bugs"
installation on buster desktop worked, (nano ~/.config/phoniebox/gpio_settings.ini can be executed successfully)

install_log.txt

topas-rec · 2020-05-30T06:22:39Z

I'm still in the progress of a fresh installation so wait for that, but I found many issues that show the issue: unary operator expected in the playout_controls.sh
See: https://github.com/MiczFlor/RPi-Jukebox-RFID/search?q=unary+operator+expected&type=Issues

Can that be related? Where is this thing coming from?

topas-rec · 2020-05-30T06:34:48Z

Fresh installed finished and issue present (I did not check if that affects volume change, but i guess it does):

Volume up error message in syslog:

s-martin · 2020-05-30T07:23:08Z

I suspect a problem here:

RPi-Jukebox-RFID/scripts/playout_controls.sh

Line 236 in 7ab0286

VOLPERCENT=`expr ${VOLPERCENT} + $ ${AUDIOVOLCHANGESTEP} \* ${VALUE} $`

I don’t see were AUDIOVOLCHANGESTEP is defined?

@topas-rec could you also execute echo -e status\\nclose | nc -w 1 localhost 6600 | grep -o -P '(?<=volume: ).*' and post the result here?

I’m unsure, if this part of the script is only executed with rotary knobs or if this issue exists for regular buttons, too.

@veloxid, @MiczFlor I don’t know, if this is related to the GPIO control or the changes from 2.0.

In addition I think we need to find out which dependencies are needed from Raspian Desktop, so they could be installed, if the user uses a Raspian Lite installation (which should be sufficient for Phoniebox).

dnmtch · 2020-05-30T09:06:38Z

If that helps I can offer to do fresh installations on a rasperry pi 3. My setup consists of 2 encoders and 1-n buttons.

i always get stuck with the configuration of gpio_settings.ini

@topas-rec could you also execute echo -e status\nclose | nc -w 1 localhost 6600 | grep -o -P '(?<=volume: ).*' and post the result here?

That is not much (Tried it twice):

pi@raspberrypi:~ $ echo -e status\\nclose | nc -w 1 localhost 6600 | grep -o -P '(?<=volume: ).*'
pi@raspberrypi:~ $ echo -e status\\nclose | nc -w 1 localhost 6600 | grep -o -P '(?<=volume: ).*'
pi@raspberrypi:~ $

I suspect a problem here:

Might be. I have not enough knowledge of shell scripts to follow up on this.

In addition I think we need to find out which dependencies are needed from Raspian Desktop, so they could be installed, if the user uses a Raspian Lite installation (which should be sufficient for Phoniebox).

That's an interesting idea. I want to install the desktop version next to see if the lite version (which I use) is the cause for this.
BTW: I did not use the lite version for the first time. So lite version worked with Phoniebox software before 2.0.

Ok, I think there’s an issue. This should return a (volume) value between 0 and 100. @MiczFlor, I don’t know where the value is really polled from and which service/application should run here to make this work.
In any case I this we should have a check and an error message here, so a meaningful value is used.

So it does not help if I test the desktop version? If not I would restore my backup.

topas-rec · 2020-05-31T14:09:27Z

Reverted to my backup where volume keys worked.

Tested the desktop version without success.
So volume buttons are no longer working in the current version (which is live).

topas-rec · 2020-05-31T18:47:21Z

Nothing about volume which is piped to grep to extract the volume. There was volume information before I guess. (See https://stackoverflow.com/questions/30323721/mpd-receive-actual-mpd-status-with-linux-bash-script)

Assuming this is related to an mpd version update - how do we get the volume information from mpd?

topas-rec · 2020-05-31T21:07:54Z

I think I got further and solved this on my machine.

fact: mpd has no volume status when this issue is present
I found somewhere that this is caused by no or wrong mixer setup in mpd
I looked at my alsamixer which usually shows only the PCM mixer control
After updating all packages through apt it shows a mixer control named Headphone and not PCM anymore

I looked into mpd.conf and there was PCM set in audio output mixer section. I changed that to Headphone and restartet mpd through sudo systemctl restart mpd.

Now the volume change works without issues.

Can someone confirm this solution who has this issue? (All packages have to be up to date)

s-martin · 2020-06-01T06:00:15Z

Thanks for investigating this!

I can also confirm that on my dev Pi I now have "Headphone".
This is mpd version 0.21.5

I agree that probably an update of MPD changed this.

We should to check, if we now need to support both cases.

s-martin · 2020-06-01T06:19:16Z

Looks like this is a change of the Pi audio behavior itself:

I don't know where to implement handling these cases and I'm not the best bash programmer. @s-martin Weather we need both cases (PCM and headphone) or just handling the up to date Raspbian version (Headphone), can you do this?

s-martin · 2020-06-01T11:09:20Z

According to https://github.com/MiczFlor/RPi-Jukebox-RFID/wiki/Troubleshooting-FAQ#audio-is-not-working Section b) you need to change the output at 2 places.

@topas-rec Could you check, if this works for you when you change the two places to Headphone and then give me feedback?

Then I would update the install script and the wiki docs.

s-martin · 2020-06-01T11:17:20Z

@topas-rec additional question:
Which Pi do you have?

I experienced this new behavior on my Pi4, but I currently don't have an older model to test.

topas-rec · 2020-06-01T13:23:06Z

Mine is a Pi Model 3B V1.2

s-martin · 2020-06-01T13:27:27Z

Ok, so we can assume that a fix is needed for more models than Pi4

Piehti · 2020-06-05T06:13:31Z

Howdy!
Any news? Got like the same issue. It's a RasPi 3B+. But I think it also comes up on the RasPi4b. At least I think I had that issues, when I decided to move the PhoeniBox from a KODIbox zu a VPNBox. I thought the issues was related to conflicting MPD usage of KODI / Phonie but might have been update-related there already.

I actually dont wanna resetup that 3B+ and 4B systems, since it took me ages to get the VPN / AP / PiHole etc running correctly. Might try on a RasPi 3B I got laying around later that day.

Stupid question: May this be related to "rpi-update"? Can anyone confirm, that users without rpi-update are concerned? Not sure, but think I did it on all devices - since the RPi 3B+ runs at 1.5ghz and the RP4b at 2.1GHZ ("slightly") OC'ed it.

Help!!!! For now I can only adjust volume on phsical volume rulers and my wife keeps shouting at my and I have to jump behind the TV and.... !!! :D ^^;

Best regards
Pete

s-martin · 2020-06-05T07:11:38Z

I think you need to check with
alsamixer
amixer scontrols
or
aplay -l

how your audio devices are now called and which number they may have.

Changed names (e.g. Headphone) need to be updated in /etc/mpd.conf, settings/global.conf and settings/Audio_iFace_Name.

If you made changes in /etc/asound.conf (see https://github.com/MiczFlor/RPi-Jukebox-RFID/wiki/Troubleshooting-FAQ#audio-is-not-working) you maybe need to update the numbers for the device as seen in aplay -l.

doliverio · 2020-06-05T12:40:18Z

Stupid question: May this be related to "rpi-update"? Can anyone confirm, that users without rpi-update are concerned?

@Piehti Yes, I was affected without making rpi-update.
Line timeBase: 0.1 # only for rotary encoder in gpio_settings.ini generates this error:

ValueError: could not convert string to float: '0.1 # only for rotary encoder

Fixing this line and changing Type: RotaryEncoderClickable to Type: RotaryEncoder solved the problem for me.

No, it’s related to a Raspberry Pi update (https://www.raspberrypi.org/blog/latest-raspberry-pi-os-update-may-2020/), which affected all Pi’s

I got my sound back working, by fixing the suggested stuff to "Headphones".
Unfortunatly I still dont got my volumecontrol back. Ich changed to rotaryclick as decriped above. No effect. What do you mean by "fixing" the line? I just deleted the comments in it - which doesnt help. :/

veloxidSchweiz · 2020-06-05T20:04:38Z

Do i understand correct, that you mean the 'volumecontrol' using buttons/rotary?
could you run the check installation srcipt:
https://github.com/MiczFlor/RPi-Jukebox-RFID/blob/develop/components/gpio_control/check_installation.sh and tell the output
maybe

Kreiszahler · 2020-06-05T20:20:36Z

veloxidSchweiz · 2020-06-05T20:53:18Z

did you install the requirements, i.e. python-mpd2
otherwise try
pip install -r requirements.txt
or just
pip install python-mpd2

Piehti · 2020-06-05T21:22:24Z

So I ran sudo apt-get install python-pip for I had no pip-support. scratchscratch
After pip install -r requirements.txt + reboot, I got python gpio_control.py back running. Still the check_installation.sh states the same error.

When hitting the vol up / down, the following error occours:

I think that is new and I can remember to have had that once, I played with the playoutcontrols when implementing video stuff and messed up something. Before I take us on a ride for ghosts, (because I did something that I didnt want to do nor can remember) I gonna backup the state for later purpose and just reinstall the dev branch to be sure.

Be right back.
EDIT ... and back...

After I found my samba-shares gone, I re-setup and resynced and chowned / chmodded the box.
The issue seems to be gone after the installation of the dev branch.

Thanks for all the support. Sorry for th inconvenience.

*Edit: More testing, the issue is gone.

@dnmtch:

Please try
sudo python3 -m pip install python-mpd2

MiczFlor · 2020-06-12T09:43:39Z

Because I can not reproduce this behaviour, but many reported the volume up / down does not work anymore, I added the option to switch volume management between mpd and amixer. Not sure if this does help, but it might help to find the issue - also with external soundcards.

What you need to do:

get the latest develop branch
go to the web app and under settings you can select which manager to use:
if you now switch on the debugging under settings for playout_controls, you will see VOLUMEMANAGER:amixer in the log files where volume is being handled

I hope this will help to narrow down the volume up/down issue

bendreality · 2020-06-18T16:29:57Z

Hi all,

I got it to work. It's the first time for me using Linux, so if one (or more) of the steps doesn't make sense, please correct me. :) And don't use this solution just yet. Wait for someone more sophisticated to review what I wrote.

I had the same issue. I couldn't control the volume via the web interface. But I was sure that the sound card was setup correctly. music could be played via web interface, but the volume control graphic was blank and didn't react to changes. Also the softvol was setup correctly. I could play music via the web interface, but had to control volume with alsamixer or amixer. But first, every time I tried to open alsamixer or amixer I got a similar error.

pi@phoniebox:~ $ amixer amixer: Mixer attach default error: No such file or directory

if I run with sudo it worked:

pi@phoniebox:~ $ sudo amixer
Simple mixer control 'Master',0
  Capabilities: volume
  Playback channels: Front Left - Front Right
  Capture channels: Front Left - Front Right
  Limits: 0 - 255
  Front Left: 153 [60%]
  Front Right: 153 [60%]

So I guessed that it's maybe right management stuff. So I did :

ls -l  /usr/bin/amixer
-rwxr-xr-x 1 root root 42517 Jun 18 13:29 /usr/bin/amixer

as root I did a:

chown pi:pi /usr/bin/amixer

and

sudo chmod a+X /usr/bin/amixer

and added the pi user to the audio group (got this from here):

usermod -a -G audio pi

And I Edited the /etc/mpd.conf to:

audio_output {
        type            "alsa"
        name            "My ALSA Device"  
        mixer_type      "software"      # <--------- changed from "hardware"
    
}

Now it works, but I surely did some stupid stuff along the way. 😆 So maybe someone with a little deeper insight can distillate this "solution" into something a little more profound. Maybe the edit of the mpd.conf is enough, but I did everything in the order I wrote it down.

So, I hope it helps. :)

themorlan · 2020-07-04T19:16:58Z

Hey,
I just installed the development version (+Spotify) on a RPi3b+ on RaspiOS Lite.
After running the install.sh I had to change permissions on ~/.config/phoniebox/with sudo chown pi:pi -R phoniebox/because it was owned by root (adressed in #1035 ). Also debug.log was owned by root and threw errors.
After that the rotary knob worked.
But I'm a little confused cause when turning the knob the change of volume is delayed by approximately 2 seconds. I did not have this behavior on the base version without Spotify. Do other also observe this?

Cali227 · 2020-07-09T08:07:26Z

Hey, I hope you can help me. I am totaly new here and i have no idea of prgramming. I just wanted to creat a music box for my daughter =)

So i have this problem: When i install the Phoniebox without Spotify, everything works very well. I changed "PCM" to "Headphone" in "Sudo nano etc/mpd.conf" ( I have no soundcard btw).

But i want to use the Version with Spotify and when i chose [y] in sthe One Line installer, the Phnoebox does not work.
I can upload a song from my computer but there is no sound and the track is not playing.

I have to say, that i dont understand most of your lines above. It would be great if you can write exactly what i have to type/change in the console.

I hope you can help me =)

Tahnk you!!!

topas-rec · 2020-07-09T08:32:49Z

@Cali227 this issue is for a volume problem. Next time you should open a new issue for your problem or search if someone already created an issue for your problem (this is a friendly advice)

Spotify version needs special handling for local files. This is explained at the readme file and links to MUST READ for users of Phoniebox +Spotify Edition

To be honest I cannot find an issue where this was already asked but I had problems with local files too and was able to solve them when I found out that I have to scan the library when new local files are added.

Perhaps that helps.
If you have further problems, please try to find an issue that already covers the problem (and perhaps already has a solution or workaround :-) ) or create a new issue. When you have volume problems you might report them here is they match the issue description above in the first comment

htpzc · 2020-07-12T18:32:36Z

Hey Guys, back from holidays :-)

Now got the time and checked what you have written and tested that.
For information again. I am using an Pi Zero W.

Checked:

cat /proc/asound/modules

0 snd_bcm2835
1 snd_usb_audio

amixer scontrols

Simple mixer control 'Speaker',0
Simple mixer control 'Mic',0
Simple mixer control 'Auto Gain Control',0

No Headphones to see. So what to do.
I checked your Dokumentation (Troubleshooting) again if there is anything i have overseen or which has been newly added.

So what i already did is:

vi /usr/share/alsa/alsa.conf

defaults.ctl.card 1
defaults.pcm.card 1

vi /etc/asound.conf

pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}

But what i not did was changing PCM to:

vi /etc/mpd.conf

mixer_control "Speaker" # optional

After reboot everything worked fine again.

As already written, before, everything worked fine and i did not have to change the mixer_control parameter in mpd.conf.
Now, maybe after this Pi update you have written, it was necessary to change that parameter.

So for me, it works fine.
I am having some trouble with noise in the speakers, but that is an other issue and i will start a new issue for that when i have tested everything out.

So thanks for your trouble investigation. It did not solve my problem but it pushed me to the needed answer ;-)

phreakadelle · 2020-07-21T09:50:24Z

I'd my phoniebox up and running since a year. Now i've did an update to use the latest version and also added some GPIO buttons. I've faced the same issue, when i did the installation from scratch (without spotify). I had a keyboard and screen (hdmi) attached. The volume control didn't work.

Now i just did a new installation from the commandline, without attaching the screen and it worked out of the box from the master branch.

Thanks to @s-martin and @MiczFlor for this awesome project.

Cali227 · 2020-07-21T10:20:28Z
