Extending Deepin apricot docker image for sound support with x11docker's corresponding options. about dockerfile-x11docker-deepin

[mviereck]

Dependencies in general are listed in the wiki: https://github.com/mviereck/x11docker/wiki/dependencies#dependencies-of-feature-options

For pulseaudio sound you need libpulse0, for ALSA there are no dependencies.

[hongyi-zhao]

OK. See my following testing and results.

In install the possible dependencies both on host and client:

$ sudo apt-get install libpulse0 pulseaudio

1. For using pulseaudio, --pulseaudio, --pulseaudio=tcp, or --pulseaudio=socket will do the trick.

2. For using alsa. I still can't figure out how to set the corresponding option. See the output of aplay -l:

$ aplay -l

For my case, the USB audio device is in using and I pass the following option to x11docker but still failed:

--alsa='card 2'

[mviereck]

Try --alsa=2 or --alsa=Device. (Either the number before : or the name behind : ).
This just sets environment variable ALSA_CARD in container.

[hongyi-zhao]

Try --alsa=2 or --alsa=Device.

Neither can do the trick. With these options, the bottom toolbar will twist/disappear in the container of Deepin desktop.

Check the output of aplay -l in container.

With these options, the bottom toolbar will twist/disappear in the container of Deepin desktop.

deepin crashes?

The desktop can be started, but the bottom toolbar will disappear and the sound card doesn't take effect.

Than rather use --pulseaudio.

[mviereck]

The desktop can be started, but the bottom toolbar will disappear and the sound card doesn't take effect.

I'd assume, if the bottom toolbar disappears, you cannot start anything to check the card.
Try something different than deepin desktop to check the alsa option.

The output of aplay -l is the same as on host, that looks good.

If you want to investigate the crash of the toolbar, run x11docker with -V. There will be lots of output, but maybe you'll find a hint.

[hongyi-zhao]

I'd assume, if the bottom toolbar disappears, you cannot start anything to check the card.

The terminal works as usual which can be used to debug problems.

If you want to investigate the crash of the toolbar, run x11docker with -V. There will be lots of output, but maybe you'll find a hint.

Even I don't use -V, the log on stdout printed by x11docker will refresh/repeat for ever when using alsa as noted previously.

[mviereck]

The terminal works as usual which can be used to debug problems.

I've checked with terminal only, --alsa=2 just works.

the log on stdout printed by x11docker will refresh/repeat for ever when using alsa as noted previously.

Just checked here, I can reproduce the issue. Is fixed now.

Sound with --alsa using deepin desktop still fails. It seems to be a pulseaudio issue that is started by deepin.
It seems pulseaudio somehow fails to use the alsa device files.
I have no idea how to fix this.
--alsa with deepin desktop works if I add --runasroot "rm /usr/bin/pulseaudio" to brutally avoid the start of pulseaudio at all.
It should be enough to remove /etc/xdg/autostart/pulseaudio.desktop, but pulseaudio is started nonetheless.

I recommend to just use --pulseaudio for deepin.

[hongyi-zhao]

Thanks a lot for you systematic analysis.

[mviereck]

I found a solution:
With --alsa x11docker now sets up a pulseaudio config file that disables the autostart of pulseaudio. Now the alsa sound works in deepin desktop, too.
Though, a nicer solution would have been to fix the pulseaudio issue itself so that it uses the alsa device files /dev/snd in container.

[hongyi-zhao]

Tried again but the problem still exists for my case. Though the bottom toolbar appears as usual, but the sound setting button doesn't appear on it. Furthermore, the aplay -l command in container will take more than 10sec to complete:

$ time aplay -l

Tried again but the problem still exists for my case.

Please check if the sound itself works. That is different from possible deepin issues. Check with speaker-test in terminal.

the sound setting button doesn't appear on it.

The button would need pulseaudio. deepin seems not to be designed to use ALSA only.

Furthermore, the aplay -l command in container will take more than 10sec to complete:

Odd.

[hongyi-zhao]

Please check if the sound itself works. That is different from possible deepin issues. Check with speaker-test in terminal.

The testing succeeded on host but failed in container as shown below:

werner@X10DAi:~/Desktop$ speaker-test

speaker-test 1.1.8

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory

[mviereck]

Please check the following command on host and in container to make sure the same card is used:

env ALSA_CARD=2 speaker-test

At first check with deepin-terminal only instead of running the entire desktop in container.

x11docker --alsa=2 x11docker/deepin deepin-terminal

[hongyi-zhao]

This way, the testings will succeed both on host and in container:

werner@adf40ae74f51:~$ env ALSA_CARD=2 speaker-test

So, presumably, it's some option(s) used by me that cause the problem.

[mviereck]

This way, the testings will succeed both on host and in container:

Good! Than check:

x11docker --alsa=2 x11docker/deepin deepin-terminal

In container:

echo $ALSA_CARD
speaker-test

[hongyi-zhao]

Still succeed and the $ALSA_CARD has value of 2 in the container which is expected.

[mviereck]

Good! Is any issue left?

[hongyi-zhao]

In --desktop mode, the above testing still succeed. Though the menu entry/button for the sound card can't be listed, I still can't use it in app, say, wechat.

That said, the problem is solved/fixed basically. From the use experience point of view, it seems the --pulseaudio based method is more convenient and efficient.

[mviereck]

Good. So from an x11docker point of view, the issue is fixed.

Though the menu entry/button for the sound card can't be listed

That is a deepin issue that expects pulseaudio. For sound control you would need some ALSA frontend.

I still can't use it in app, say, wechat.

Likely wine needs a configuration to use ALSA.

From the use experience point of view, it seems the --pulseaudio based method is more convenient and efficient.

Yes. deepin is entirely designed to use pulseaudio.

[hongyi-zhao]

I still can't use it in app, say, wechat.

Sorry for my typo. I should have typed as below:

Good, than all is well.
