my problem: the sound work but while watching to something for ex youtbe video there is interrupt by switching between 2 audio output i uncheck option to autuomatically switch running stream when a new output device becomes available but still have this problem.
in yast sound configuration i found 2 card one ga104 high definition audio controller and other is starship/matisse hd audio controller
thanks in advance

I would start by using ‘pavucontrol’ to configure the desired profile and output configuration. You can also control application-specific behaviour using this GUI utility.

thanks i dont know but until now the problem dissapeared, after i installed pavucontrol. but if it worked whats the reason.

still i have the problem so any other solutions please

Well, did you set the desired output as required? Also when playing a stream, you can set on a per-application basis. It’s not clear what you’ve tried so far.

its less common now and i notice already when i set sound so high it occure, and i notice -i beleive- the sound become louder and clearer which something i like. i feel i need to test it more this week as i dont watch youtube or listen alot so thanks for now

It sounds like hardware instability, likely exacerbated with high-powered sounds causing power load spikes. I’d get some new USB speakers or warranty swap.

If the speakers work fine on another motherboard, I highly suspect USB-related issues on Ryzen.

thank you, its SOLVED, its bad usb speaker just.
thanks again
