Debian 11 sound issues when switching to 5.1

#1 Post by jorgegmayorgas »

Hi

I am testing Debian 11 and I cannot get surround Analog 5.1 audio output working with a Creative Labs Sound Blaster FX, only Stereo Duplex sound output . If I change profile to 5.1 with pavucontrol , there is no sound and output device turns to Dummy Sound device. If I revert the change to stereo ,sound works perfectly

Sound card is working as expected on Ubuntu 20.04 with kernel 5.4 and Debian 11 comes with 5.10. It is the only difference I see


Is anyone suffering similar issues with this card or onboard audio (that also have 5.1 analog output)?

Regards,
Jorge

Can you try to run isenkram-autoinstall-firmware, from isenkram-cli package, and see its output?
As given example here

The kernel may have changed the need for model=string for your device but what is your codec?
as per
viewtopic.php?f=16&t=53708
run

Code: Select all

cat /proc/asound/card*/codec* | grep Codec
then we can go to the model=string site at
https://www.kernel.org/doc/html/latest/ ... index.html
click on your codec to reveal what to put in model=string
if that were the only thing you needed to do, use root powers to create /etc/modprobe.d/model.conf
with contents
options snd_hda_intel model=string
I use understems which work for me YMMV
then full reboot.
