After installing the 2021-02-28 stable update I experience a very stange audio behavior.
Using the internal speakers all sound is fine.
When plugging in my headset is seems that the headphones play some surround channel, even if the audio source is a normal MP3 without surround information.
When plugging in a regular headphone (i.e. no microphone included) sound is fine.
So, it has something to do with the microphone. Instead of detecting that a headset is plugged in it seems the system thinks that a surround device is pluggin in.
Any ideas?
