Alsa questionable content

Talk status

This discussion is done as of 2022-02-14.

This Alsa section feels bogus as the hdsp info is for a specific sound board and chip [[1]]. The -conf packages should not be necessary either. This looks like improvised guesses than real facts. --Grknight (talk) 14:24, 9 October 2020 (UTC)

I added the hdsp because of my headset that uses a lookalike name for the microphone. This maybe can be removed. Sspreitzer (talk) 15:26, 9 October 2020 (UTC)

The profiles in pactl list cards where wrong without the topology and ucm packages. I booted a live Ubuntu and recognized the profiles where different there. "HiFi". I grepped through the files and discovered that they are rooted in the topology and ucm packages. After installing them, the profile information in pactl changed Sspreitzer (talk) 15:26, 9 October 2020 (UTC)

Looks like this discussion has been done for about a year and a half. --Maffblaster (talk) 23:08, 14 February 2022 (UTC)

Microphone now working

Talk status

This discussion is still ongoing as of 2024-12-21.

It took me a while to get the digital microphone of the X1 G8 to work, but it did, eventually.

I'm reasonably sure that you need to blacklist the modules snd-hda-intel and snd-soc-skl and that you have to allow the kernel to load SOF firmware, which makes sense as the author suggests emerging sys-firmware/sof-firmware.

I believe that the key configuration in the kernel is CONFIG_SND_SOC_SOF_INTEL_TOPLEVEL=y, and I admit that I used brute force and enabled everything under it as a module. Kernel version 6.6.62.

Somebody who knows about Linux audio better than me might be able to establish exactly what is required for the digital microphone to work, and I'll be more than happy to provide more information if required. Gabrielg (talk) 14:38, 21 December 2024 (UTC)

UPDATE: I've just removed the Intel HDA driver from the kernel completely, for those who like doing such things, and can confirm that you don't need to blacklist it (obviously) and that sound continues to work as expected. This means that the suggestion in the main article that this laptop uses snd-hda-intel isn't quite right, or that at least that module doesn't leverage all the capabilities of the audio system.

I haven't tried to whitelist snd-soc-skl yet, will update here if that ever happens. It can't easily be removed from the kernel without major experimentation. :) Gabrielg (talk) 15:45, 22 December 2024 (UTC)

If you have confirmed it then can you please update the wiki so the next person doesn't have this issue please?
