If alsa doesn't recognize a device, you won't be able to use it. If alsa knows about the device, I would then use pavucontrol to activate it by setting it as default. I think that f35 was still using pulseaudio as the default sound controller on top of alsa, and that pipewire didn't become the default until f36. If both are installed, it can lead to issues with sound as they compete for the hardware. Pick one, and remove the other. > > Machine: Dell Precision M6800: i7, 16Gb RAM, dual 1TB 5400rpm hdds, > intel video and AMD FirePro M6100 graphics. > > Current kernel: > Linux jupiter.in.tedroche.com 5.19.4-100.fc35.x86_64 #1 SMP > PREEMPT_DYNAMIC Thu Aug 25 17:41:09 UTC 2022 x86_64 x86_64 x86_64 > GNU/Linux > > lspci -v shows: > 00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core > Processor HD Audio Controller (rev 06) > Subsystem: Dell Device 05cd > Flags: bus master, fast devsel, latency 0, IRQ 41 > Memory at f7d34000 (64-bit, non-prefetchable) [size=16K] > Capabilities: [50] Power Management version 2 > Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit- > Capabilities: [70] Express Root Complex Integrated Endpoint, > MSI 00 Kernel driver in use: snd_hda_intel > Kernel modules: snd_hda_intel > > 00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset > High Definition Audio Controller (rev 04) > Subsystem: Dell Device 05cd > Flags: bus master, fast devsel, latency 0, IRQ 42 > Memory at f7d30000 (64-bit, non-prefetchable) [size=16K] > Capabilities: [50] Power Management version 2 > Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ > Capabilities: [70] Express Root Complex Integrated Endpoint, > MSI 00 Capabilities: [100] Virtual Channel > Kernel driver in use: snd_hda_intel > Kernel modules: snd_hda_intel I think that this device should be the default. Because they are both hda-intel using snd_hda_intel, I wonder if their recognition during boot hasn't changed lately, and your default is now the first instead of the second. pavucontrol can fix this, but you can also set up a sound configuration file assigning positions to the devices, though that might not work for the built in audio on the CPU. It is possible that the sound device has developed hardware issues. I have had a sound device fail, but usually it won't be recognized as yours is when that happens. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
