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



Hi Rein,

It's said "digital audio" but I'm not clear about PCM yet.
Hmmm...ALSA is always annoying me, really easy to install but
very difficult to setup due to lack of easy guide/doc.
The worst thing is that there is no suitable example for Delta 44.

At any rate, you can obtain lots of informations (I hate these :-(:-) here;
http://www.alsa-project.org/documentation.php3
There are many descriptions including mini howto etc.

Are you trying to install ALSA?
Don' waste your time :-)
