Hi @damencho ,
Need you help in fixing this issue. I’m using Jibri/latest docker image in container. But getting the FFMPEG error:

Did you enable/install snd-aloop module on host?

Hi Prashanth,
Yes, I think it’s already complied. I’m using PaaS, on same platform if I use entire Jitsi stack with docker containers it works fine.
root@node98601-env-2068478:~# lsmod | grep snd_aloop
snd_aloop 4242 -2
snd_pcm 4242 -2 snd_aloop
snd 4242 -2 snd_aloop,snd_timer,snd_pcm,snd_seq,snd_seq_device
When I directly install a container from docker hub, FFMPEG showing error.
Not sure what’s the root cause. Looking for expert’s help here.
Thanks

@damencho @saghul @Freddie
Requesting your attention, as I’m stuck with this.
Please advise.

Probably the container has no permission to access to the sound device.

@nky Run the following commands and share your outputs:
su jibri
aplay -l
arecord -l

Freddie:
arecord -l
Thanks for your inputs, got something interesting.
root@node98601-env-2068478:~# su jibri
aplay -l
: not found
aplay: device_list:272: no soundcards found…
arecord -l
arecord: device_list:272: no soundcards found...
But I see .asoundrc in place. When I run these commands as root user.
aplay -l

Thank you @emrah , you seem to be right here as per output pasted below.
As root user - I see soundcard devices. But as Jibri user - not able to access.
How can I give the jibri user the access to soundcard devices.
Please suggest.
Thanks
My 2 cents…check the groups jibri belongs to.
jibri : jibri adm audio video plugdev jitsi
I think that’s the issue. It is not in group ‘audio’. I just removed it on my system from group audio and I see same output you were seeing.

@Prashanth Here is what I have got.
root@node98601-env-2068478:~# groups jibri
jibri : jibri adm audio video plugdev jitsi
root@node98601-env-2068478:~#
But still situation remains the same.
So even now ‘aplay -l’ says no soundcards?
Try adding jibri to group ‘root’ and then check if recording works. I know it is not a solution. But check if it works until someone else have some other ideas on how to fix this.

@Prashanth This is even more surprising. Added, but still the same.
root@node98601-env-2068478:~# groups jibri
jibri : jibri root adm audio video plugdev jitsi
root@node98601-env-2068478:~# su jibri
aplay -l
aplay: device_list:272: no soundcards found...

Where is your .asoundrc located?

@Freddie .asoundrc is in /home/jibri/ .

What’s the output of the following:

@Freddie It’s as below.

Try deleting and recreating .asoundrc

Who run the Jibri service on Docker?

I’m not familiar with Docker. Attach the container and run ps aux
