Description Rolf Eike Beer 2024-05-06 07:15:48 UTC

Sorry about the too generic component, I don't know where to but it. Please reassign.

SUMMARY

While he mixer popup is visible (i.e. I have it open and the mouse in it) the audio volume is normal. When the popup hides the volume is reduced considerably after a few seconds. Opening the popup again brings audio back to normal.

This is somewhat random, i.e. I observe this behavior every few bootups, but not always.

Likely the volume monitors. We install a monitor on all streams to show the live output/input peak. This might cause a headset to switch modes (e.g. from high fidelity audio output to handsfree output + microphone). Might have other effects, too.

I can't reproduce (naturally :p). 

Maybe share your sound card model, that's often either your video card or your motherboard if you are not using a dedicated sound card.
Also can you check if `journalctb -b | grep plasma`  show anything interesting when the problem happens?

Thanks!
