Hi *, I use a Plantronics USB headset, which has volume buttons (level up/down, mute). Pressing the mute button, the headset says "open mic on"/"open mic off". As for applications like Citrix workspace app or Microsoft Teams the mute state was synched, so that the app also shows a mic symbol, that was crossed out or not. If such an app was connected, the red led at the USB plug also showed the state of the mute button; if it was red, the headset's micro was muted. I could either press the headset's mute button or the virtual mute button in the app with the same result. Starting today, this sync stopped working. As for the GUI itself everything works as usual - "open mic on"/"open mic off" and level up and down. But the apps don't get the mute state any longer. To really mute or unmute the mic I have to klick the virtual button in the app, pressing the physical mute button of the headset has no effect. Also the red led does not show the mute state any longer. The only change from yesterday was the installation of the latest Tumbleweed snapshot 20230307, but as for the history it contains no package that could have such an effect - at least not obvious for me. I tried switching between pulseaudio and pipewire to no avail. Any idea, what might have caused this and what to do to get the desired state back? TIA. Bye. Michael.
