Hello,
I am using Silverblue 42 and in sound menu interface changing randomly. I already complained about it in one of the topics, but no one answered, so I am making a separate topic.
I am using audient id14 audio-interface:
Thank you.
Can you associate the changes in the GUI with some events in the system log? If so, you might be able to filter/silence the events to keep the GUI from reacting to them.
Leave sudo journalctl -f running in a terminal and watch to see if a specific message is displayed when the change happens.
I think, it changes only after reboot.
Maybe this message is related:
usb 1-12: 11:0: cannot get min/max values for control 11 (id 11)
If it only happens on reboot, then that might be a little harder to trace.
If it is on the USB bus, then maybe what shows in the GUI depends on what order the devices are detected?
Perhaps you could disable or otherwise block the undesired device so it does not interfere?
There are some notes on disabling audio devices with Wireplumber here: https://askubuntu.com/questions/1118673/disable-docking-station-sound-card-while-still-being-able-to-use-a-usb-sound-car#:~:text=2.,service%20to%20restart%20Wireplumber.
Disclaimer: I’ve never attempted it.
Not specific, but I had something similar with a USB audio dongle between Fedora 42 and openSUSE Tumbleweed both GNOME (USB audio presented fine after reboots Fedora, but randomly reverted on oS at some point). I think it’s a race condition where USB might report the audio devices after GNOME or the audio system scans for them.
I didn’t fix it and just went back to onboard 3.5mm 
But one idea might be to use a power USB hub, or remove the audio device’s power so it comes from the computer (if possible).
