Package: alsa-source
Version: 1.0.8-4
Hi,
I have 3 problems with alsa axz driver (for ICH6 + CMI9880 on Gigabyte
GA-8GPNXP Duo matherboard):
1. /dev/dsp problem: When I use TV application (e.g. xawtv) I haven't sound
(line-out TV card connect to line-in).
Temporary solution: I modifity "parrot.c" /dev/dsp demo program, so as to set
correct parametr for /dev/dsp and copy date form /dev/dsp to /dev/dsp
(similary to: dd </dev/dsp >/dev/dsp) and sound work.
2. poor quality problem: When I play any sound file I hear this sound and
rustle.
3. alsamixer don't control "Capture Volume" and "Capture Switch"
Thanks for helping,
Robert Paciorek
