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 :-)
