Thanks. Looks interesting but I am not clear how to use it without oss, 
alsaplayer, etc. I just want the hw:0 or other device to be multiclient. In 
other words, I can start up kplayer and hydrogen/jack at the same time and 
flip out :-). Mostly, something is eating the device but not necessarily 
playing and I want something else to play without closing the first 
something.

Do I use the number 5 or number 6 .soundrec? I am not playing anything through 
oss (except Wine and I have not heard any audio coming out of that yet :-) ). 
Does the plugin itself need be installed or is it in alsa (alsa sources with 
kernel 2.6.15 or from Debian Sid)?
