Thanks for your response! Using "Gnome Volume Control" v2.8.0 (or earlier), the "PCM" works like a "binary variable", so: 1) if the PCM volume is between 1% to 100%, then the volume you hear is at maximum (the same volume is at 1% and to 100%). 2) if you put PCM volume at 0%, the PCM volume go off, and you can't hear more mp3, wav, etc. So: PCM = 0% -> PCM volume off PCM = 1% to 100% -> PCM volume at maximum This way, the only way to put the volume a little down, is using the speakers. Is this the way the mixer should work? (because of the lack of support) Thanks in advance!!
