Comment 45 for bug 1926165

Thanks for posting the fix, I tired it out on my Yoga 9 14ITL5 on both the Fedora 35 5.14.18-300.fc35.x86_64 kernel and the Ubuntu 21.10 5.13.0-19-generic kernel with minimal luck. With DAC1 and DAC2 at maximum, the rear speaker sounds like nothing is coming out of it. When DAC1 is turned down to 0, there is audio coming out of the rear speaker, however, the audio output quality is rather poor and tinny.

Looking at the kernel source, https://github.com/torvalds/linux/commit/9ebaef0540a981093bce5df15af32354d32391d9 it appears that the kernel version the fix was first released in was 5.13rc4 and looks to appear in all newer tags, so the fix should be in use on my system. Based on the experiences shown above, what I'm experiencing doesn't seem to be the right behaviour.
