I have stuck into a strange problem. Everything was working fine a couple of days ago.
I use external USB mic Yeti Blue. This has a zero latency speaker output as well. I use that for my headphones. Whenever I plug the USB in, it is detected and it becomes the default device for INPUT as well as OUTPUT. This is fine. The problem is that the volume of speaker is zero. Though the master volume is NOT zero. So what I use this workaround - launch ‘alsamixer’ and select “Blue Device” using F6. And then increase volume (F3 - playback). Here the volume is always zero when I plug the device. I don’t what has changed in last few days. Is there a way to tell Debian to save the previous volume level of externally plugged-in device?
