Hi Colin, I must admit I've not looked much at our PulseAudio implementation but i really thought it supported multichannel directly. I tried to test it last night, but I was unable to configure pulse for a profile of more than 2 channels in pulse settings (stock lucid version). I figured that had to be done first. When that didn't work I didn't even try anything in xbmc. Should that be required first? Any hints on how to get pulse to recognize all my analog outputs? I'll try to stop by #pulseaudio tonite and we can see if we can make sure it works. Would be nice to make sure before we release our next release. /Joakim > -----Original Message----- > From: Colin Guthrie [mailto:gmane at colin.guthr.ie] > Sent: den 14 oktober 2010 19:23 > To: General PulseAudio Discussion > Cc: Joakim Plate > Subject: Re: [PATCH] AC3 passthrough support > > 'Twas brillig, and Joakim Plate at 14/10/10 13:40 did gyre and gimble: > >>> To use this feature from other frameworks (gstreamer, etc), we will > >>> need a tagged release to #ifdef code related to AC3 passthough for > >>> backwards compatibility.
