No sound after upgrade to 5.1
The 3.5 version worked just fine until recently, when joining conferences required upgrade. So I did that and now there's no audio / mic.
On the audio settings page the "Test speaker" button as well as other controls are disabled. Setting "Speaker" to either "Same as system" or "Built-in…" doesn't change anything. Microphone dropdown is disabled and empty.
How can I help to diagnose this?
I did a little bit of digging and found out that playing sounds via Pulse inside the container actually works. So it looked like something changed in Zoom itself.
But then I rolled back to 3.5 image and was surprised to see the same problem there. Any ideas what it could be?
I've tried the latest build on Docker Hub 5.1.422789.0705 and I didn't encounter any issues with the audio.
You may find something by displaying Zoom's stdout/stderr by using the following command:
docker logs zoomus
There's also a logs file in ls -l ${ZOOM_HOME:=$HOME}/.zoom/logs where you can find more details.
In the log I find a line saying
No PulseAudio daemon running, or not running as session daemon.
PA ist running and can be accessed by pacmd outside the container.
I still have no solution for this problem but a new observation to share:
When opening a shell in the container I can access PulseAudio as root by giving the PULSE_SERVER variable on the commandline
mlo@fangorn:~$ docker exec -it zoomus bash
root@c1e3d9537e8e:/# PULSE_SERVER=/run/pulse/native pactl info

whereas trying the same as the zoom user it fails:

zoom@c1e3d9537e8e:~$ PULSE_SERVER=/run/pulse/native pactl info
shm_open() failed: No such file or directory

In an strace I found this lines:

write(2, "Connection failure: Protocol err"..., 35Connection failure: Protocol error) = 35
I'll run zoom als root inside the container as a workaround for now but I#m not happy with it ...
I played around with settings, permissions, running xterm -ls inside the container and starting zoom from the commandline with various variations but nothing improved the issue
Only running zoom als root makes it work as expeced
Looks like the newest version crashes entirely due to the same issue:
No PulseAudio daemon running, or not running as session daemon.
Something went wrong while running zoom, exit code is 1.
@mlo-poc could you share what you did exactly to make it work? What do you mean by "running zoom als root"?
