Comment 4 for bug 2043524

Same thing is happening here with an Asus Z790. It was working properly on 23.04. Not on 23.10 the sound works like this:

HiFi 2.0 - Very low sound. I have to crank the sound to max to barely hear it.
HiFi 5.1 - Only the front ones sound (but they sound around 60% when the volume is at 100%, meaning, the actual volume of them is not full). The rear speakers dont even sound. You have to put your ear to the actual speaker to hear it.
HiFi 7.1 - The front ones work correctly but any others do not.

The headphones still work correctly via bluetooth, but the whole sound experience basically is dead. Everything is either very low or speaker mode or nothing at all.
