[pulseaudio-discuss] AMD chipset HDMI and SPDIF outputs lack surround sound modes

[Yfrwlf]

Hello,

     I'm running Ubuntu 12.04 with two computers both with AMD video 
chipsets.  Both of the sinks I need to output sound on have no mode 
setting in Gnome sound config.  The analog outputs show surround options 
available, but S/PDIF and HDMI options only offer stereo output.  Is 
there some way in which I can contribute to enhance Pulseaudio so that 
future versions will have this corrected?

     On a separate topic, is there a way to force it to output with more 
channels until a patch is applied?  I've tried messing around with pacmd 
and can't figure out how to set the channels.  Does this need to be done 
through editing one of the config files?

Thanks!
