Hi
I am on a sidux aka Debian unstable.
old k vmlinuz-2.6.27-10.slh.1-sidux-686
new k vmlinuz-2.6.28-0.slh.11-sidux-686
On old k and using sidux in live cd mode I had sound in front connectors.
the live cd mode was scratchy sound.
After kernel upgrade, no sound at front
using alsamixer or kmix the settings were initially unchanged ie
front unmuted volume highest
2) but on new k ...I tried something else which puzzles me.
I have 2 headphones one in front and one in back
If I mute the front in the mixer...I lose sound to the back
Nothing I do in the mixer appears to enable sound at front.
Any clues?
