I'll try that out tonight. > also, could you check multiple playbacks? I'm getting some interesting results with this :-) I'm booted into KDE and I have artsd running... As KDE starts up artsd plays it's audio file fine, with all four speakers. If I set xmms to use the OSS output plugin, the mp3 I'm playing starts up fine with all four speakers... Somewhere along the way, the rear channel drops out completely. It seems to be hit or miss. Sometimes I can actually get through the file without any problems. Sometimes it drops out nearly immediately. A sure fire way to duplicate the problem, though, is to start up alsaplayer with another song.. Both songs will now play on all four speakers. So now I have artsd running, xmms running with the OSS plugin, and alsaplayer is running :-) If I quit alsaplayer, the rear speakers will cut out for the song playing on xmms. If I then hit "x" to restart the song, it begins again with all four speakers :-) > > In addition, alsamixer shows a new option "4ch Duplication" so, in theory, > > I can turn it off and have two alsaplayers going, one stream on the front > > channel and a different one on the rear channel.

The only reason I mentioned it this time around is because I thought it was nice that it was still possible to do this by muting that switch :-) Adam _______________________________________________________________ Have big pipes?
