I recompiled snd-hda-codec-realtek.ko using attachment 298363 [details]. When I reboot the Yoga7i both speakers work fine as @Max described. But alfter S3 sleep wake up both speakers become right channel.

I changed `0x2a` to `0x1a` in line 8223 and updated snd-hda-codec-realtek.ko and then both speakers have the correct channel after S3 sleep wakeup.

I assume that the channel will be reset after boot, and the speakers will be conditionally activated after S3 sleep wakeup.
