Re: Instable Device = sound crackling

;-) working again as expected. I recovered my kde & hotkey controls !

so simple ! now I need to understand why this is happening. If you have an explanation, it is welcome! why is it switching module like this alone ? that's really weird ... you were supposing that there is a load of jack change events fired. What does that mean ?

Re: Instable Device = sound crackling

"Something" on your system thinks you are constantly plugging and unplugging something into the digital out jack, which will lead pulse to switch profile if that module is active. Do you get events shown in

udevadm monitor

? This something could be pretty much anywhere in the stack, maybe a buggy kernel or maybe there's some dust or something in your physical jack that leads to false alarms

Re: Instable Device = sound crackling

nope nothing. I'll try cleaning then ;-)

I have some error in dmesg but actually it concerns my cpu. Ok, I think I understand where it is coming from.

Many thanks anyway, you solve it in 2s while I was searching the web for many days !
