I like Stanley's approach. Otherwise, Justin will have to figure out
where to put all the new settings:
Output 1-channel audio to:
2 channels (stereo L+R)
4 channels (Ctr-FR-FL-Rear)
5 channels (Ctr-FR-FL-RearR-RearL)
...
Output 2-channel audio to:
2 channels
4 channels
5 channels
...
And, we still have to factor in the existing "Independent Muting of Left
and Right Audio Channels" (for those with dual-language broadcasts).
All this can be done in ALSA's configuration with translation tables...
After all, it is a configuration that's tied specifically to audio
output hardware (card and speakers and, perhaps, A/V receiver), so in my
mind, it's an audio hardware (ALSA) configuration thing.
Sure, the current situation isn't ideal, but instead of putting code in
Myth to do ALSA's job, I think we just need to improve Myth's support
for ALSA (and, perhaps, other audio output classes). For example, one
approach would be adding some code to Myth's playback groups for
selection of audio output devices. Another might be allowing users to
select output devices during playback (kind of like changing aspect
ratio during playback). Adding both might be nice, too.
