Hi.
I recently installed Fedora 41 Workstation on my Lenovo Legion Pro 7. My previous Fedora 40 install also had broken audio, however, I was able to fix it with the following command:
sudo tee /etc/modprobe.d/snd-hda-intel.conf <<< "options snd_hda_intel power_save=0"
However, now, this is no longer working. Not only that, but I also discovered a weird thing. Running cat /sys/module/snd_hda_intel/parameters/power_save gives me 10, instead of 0. Shouldn’t the power_save parameter be a boolean value? Where does 10 come from? I’d expect this value to be either 0 or 1.
I’m running kernel version 6.12.5-200.fc41.x86_64.

I tried adding enable_msi=1 to /etc/modprobe.d/snd-hda-intel.conf, but the journalctl log still says Disabling MSI, so it looks like the config file is ignored. Also, power_save_controller=N doesn’t make it work either. Replacing _ with - does not work either.
Edit: I managed to fix this issue, albeit it would be still nice to what’s going wrong. I reverted back to the 6.11.4-301.fc41.x86_64 kernel and noticed that the sound was working fine, and the journalctl log was different:

Looks like with the newer kernel, the snd_hda_codec_realtek hdaudioC1D0: bound i2c-TIAS2781:00 (ops tas2781_hda_comp_ops [snd_hda_scodec_tas2781_i2c]) line is missing.
I ended up adding the model=,17aa:38a8 parameter to /etc/modprobe.d/snd-hda-intel.conf, which fixed the audio on the newer kernel. I got this idea from this comment.
Side notes:
- I got the model ID by running
cat /sys/class/sound/hwC1D0/subsystem_id. - The
/sys/module/snd_hda_intel/parameters/power_savevalue is still10. I don’t know what that means nor why. /sys/module/snd_hda_intel/parameters/power_save_controlleris stillY, even thoughpower_save=0is set
