Just installed the latest patch for 13SGen2.

Firstly, applying the patch linux-5.12-legion-sound-0.0.9-003.patch leads to some errors :

So I directly applied linux-5.12-legion-sound-0.0.9.patch and was able to compile and install with no error.

The speaker sound is definitely better, the overshoot on the volume control is manageable.
Its hard to compare to windows because of Dolby, but its close.

The sound works after unplugging headphones (tried it multiple times).
The headphone sound still has some cracking noise and the bug on the volume control reappears (at least from what I tested). The sound on headphone is still pretty good.

I noticed a bug, rebooting the computer with an HDMI cable plugged in removes completely the sound card. This bug was also present in version 0.0.7 of the patch.
