I'd like to control the master volume with the designated volume buttons. I'm using Ubuntu Studio and it's got both Pulse and Jack.
Now, I think I would be happy if I could control PulseAudio because I normally stop Jack when I don't need it. I've tried the command
amixer set Master 5%+ but it didn't work. I thought it would control ALSA, which is under either Jack or Pulse. Is that correct?
Does anybody have any suggestions?
