Hi, I am running Ubuntu Studio 22.04. Pulseaudio is disabled, my input and output device is a USB audio interface, a Presonus Studio 24c.
I need a way to briefly mute the playback card, from within Jack or something, and on a set schedule. Alsamixer shows that this card has no controls so I can't do something simple like have cron issue an ALSA command to mute/unmute the card.
Maybe there is something clever that could be done from within Jack, but I don't see it offhand. Does anyone know of a way to do this? Thank you!
