[PATCH] Fix surround playback with pulseaudio

Added by Adriano Moura over 11 years ago

Seems that Audacious pulseaudio output plugin has never set an appropriate channel map. This little patch will use pa_channel_map_init_auto and assume WAVEEX style channel mapping. Audacious can now properly output any 5.1 file I trow at it.

Before:

sample spec: float32le 6ch 88200Hz
channel map: front-left,front-left-of-center,front-center,front-right,front-right-of-center,rear-center
resample method: copy
module: 6
client: 20094 <Audacious>

Now:

sample spec: float32le 6ch 88200Hz
channel map: front-left,front-right,front-center,lfe,side-left,side-right
Surround 5.1
resample method: copy
module: 6
client: 20114 <Audacious>

For correct 4.0/6.1/7.1 surround mappings you will need some pulseaudio patches, but I'm still working on this. WAVEEX seems to be wrongly implemented in pulseaudio right now.
