I'm on vidalinux v1.1 (VLOS 1.1) an= d I'm using their latest sources, which are essentially a modified sources = from gentoo.

The f= irst one should be the case for sound to work, if I turn it off, I go back = to the old behavior. > >I believe before I could not change the "external" setting, although I'm s= ure I tried, but now I set it on and everything has started working. Good = Luck. > >Torsten > Well, even though I'm running the new kernel, the laptop began the old beha= vior again where I could only get sound on the headphone jack and the volum= e was very low. The only thing I changed related to sound was to boot into Windows last nig= ht during my college class and I muted the sound volume to keep the compute= r quiet during class. That's when the old behavior started. So I rebooted into Windows (XP), unm= uted the sound, rebooted into Linux, and everything was back to normal! I don't know what Windows did to the volume when it muted it, but I do know= that ALSA driver intel8x0 is unable to undo it. I have to boot to Windows= to unmute, then Linux works again. Torsten |
