Sure, I would be glad to tell you what I have done so far.

First, I am using Debian so I did an apt-get install alsa-oss. I 
then placed the attached asound.conf in /etc. Then I recompiled 
the kernel and took out the two OSS entries, rebooted and I can 
now do the following:

aoss ogg123 myfile.ogg and while that is running I am able to do 
things like:

aoss saytime

And I can hear both audio streams. I have not yet been able to 
get it working with zinf though.
