[Gwc-general] Re: problem getting gwc to use alsa

A bit further. It works a bit better if you use "plughw:0,0" for the "Audio 
device" setting. Mostly it plays back for a few seconds (up to about 20 
seconds) before going into the loop (like below). And it recovers if you stop 
the playback. There is no regularity in it, sometimes it plays seconds, next 
time it directly loops.

This is -barely- usable, so I guess I'll continue like this for the moment.

Johan
