ALSA: no sound, no error!
I'm experiencing a similar problem with similar hardware. I have a
sager np3880-v laptop, the sound works great in windows. In gentoo
linux, everything seems to be working fine as far as I can tell,
except no sound comes out. cat /dev/urandom > /dev/dsp makes no
sound. Maybe someone knows what they're looking at here better than I
do. I'll paypal $50 to whoever provides the magic solution.
