Re: [linrad] Re: AC97 Sound card issues.

Hello Rein,
I have no problems with ALSA so the site may only have been temporarily
down.
alsamixer and gamix are part of the alsa package ( in fact there are 4
packages together).
Om my laptop with the via82xx card the kernel driver ( via
82cxxx_audio)works a bit but it no well controlled.
Using alsa-0.9.2 alsa installs well the snd-via82xx . the gamix or
alsamixer(gui) controls everything and linrad has no problems at all.
