ok, thanks...
Works great, kind of, but if the terminal is even minimized to do anything else not to mention closed the setting change dies. You have to go back and nudge the settings up or down to refresh them.
Now for me it is a fix for I think sloppy solder shorting a SM resistor in a BT headset, but it is a PITA when I also need to do stuff beyond music or audio books that I can't control exclusively with the answer,pause fwd,bkwd buttons on the BT dongle.
edit:
Alsamixer also times out after something like 30-60min.
