I used to use linux back in the days, so I have some experience with it, but it's been a while. Any help on this is appreciated.

Thanx
Stretch

Reply to me - Note to self - check the actual volume control, because maybe the new install did something to the settings.

Surround control fixed the problem. Thanks for making me think.
