Comment 0 for bug 1939052

All 3 models need the appropriate HDA verbs sent to properly initialize the sound hardware.

Additionally, the Legion 15IMHG05 needs automute disabled otherwise speaker output will not return after removing headphones.

The good news is that I have working patches for all 3.

However, the 13s Gen2 reportedly has some weirdness on the volume control. I don't have this model of laptop so there's not a lot I can do. It seems tuning the volume up and down using the keys on the keyboard can jump the volume up and down in large increments. Volume adjustments via a GUI do not have this issue.
