Hello everybody,
I use two Linux-boxes, connected by LAN -
(1) a Lenovo box, running Debian 10 (buster), kernel: 5.10.0-0.bpo.8-amd64 x86_64
Audio: Device-1: Intel 5 Series/3400 Series High Definition Audio driver: snd_hda_intel
Device-2: Generalplus type: USB driver: snd-usb-audio,uvcvideo
Sound Server: ALSA v: k5.10.0-0.bpo.8-amd64
(2) a Sony Laptop, running Kubuntu 21.04, kernel: 5.11.0-38-generic x86_64.
Audio: Device-1: Intel 82801I HD Audio driver: snd_hda_intel
Device-2: Generalplus HD 1080P WebCam type: USB driver: snd-usb-audio,uvcvideo
Sound Server: ALSA v: k5.11.0-38-generic
Both the kernel and the ALSA Sound Server are newer on the laptop. Should I maybe just
upgrade both these components - provided this is possible on Debian 10?
As against on the laptop, there is NO built-in microphone device on the Lenovo/Debian machine,
but the webcam (Generalplus...) does of course include one that works on the laptop.
I am trying out Zoom on both machines with the result that everything works fine on the Laptop,
while on the Debian box, the microphone is not recognized (the video is o.k.). I wonder what
might be the cause of the problem.
Regards H. Stoellinger

Re: Microphone not recognized
Thanks,
Could you edit the post and put the outputs in code tags (</>) please?
As far as I can see the microphone isn't muted, the sound is turned up and the correct card is active.
I suspect that that the hardware is new and not identified correctly by even the backport kernel in Buster as you suspected. (There is a more recent backport kernel, 5.10.46+4~bpo10+1 - you could try that.)
Could you post the
output for the working computer? The webcam may be identified differently, which would confirm this.

Re: Microphone not recognized
The webcam is identified in the same way, so no clues there, as far as I can see.
Just to rule out the possibility that this is a Zoom issue, could you try:
and speak into the mic for ten seconds and then run
to play back the test.
Just to rule out the possibility that this is a Zoom issue, could you try:
