Comment 646 for bug 1958019

Quick update: it works! sort of...

I applied the first fixup (LEGION_15IMHG05), but it didn't work, and the second (YOGA7_14ITL) didn't either. But while booted from the kernel with the 2nd fixup, I decided to give it a quick suspend/wakeup cycle. After the wakeup, there is sound! But only from the left speaker. The sound is coming only from the left channel.

I will report back after retrying the 1st fixup, this time with a suspend/wakeup cycle.
