I mean top "+" "-" switch.
Tested once again
and it worked for Radio applet
and didn't for media player.

After switching off and on, sound is low as before.
So the above shell code lines should be run as a shell script
on system start up, every time 2008He is down and back up.

Tested today BBC Radio 1 and sound is low either played as an applet
or via Media Player.

Yesterday played much louder after setting 100 to volume levels.

It looks like your solution is excellent but my 770 keeps crashing.
