Comment (by ignissport@…):
I've just run through all the tests myself on v0.26.1-7-gdc1d80 and
v0.27-beta-89-gfb1a3c5.
All tests played back perfectly in both versions. My AV receiver reported
input sample rates that matched the input files, and it changed with the
tracks.
The only thing I noticed was playing a raw 5.1 DTS file in the music
player - it played back fine, but in the past it would perform a DTS
passthrough, where now it appears to decode it to multichannel PCM. AC3
passthrough still works fine from Live TV and the video player for streams
with DD/DTS audio. It's just the music player that decides to decode it to
PCM. The MythMusic audio device is set to 'default', so I'm not sure why
it behaves different to the other modules. That said, it's no big deal -
it doesn't really matter whether the PC or my AV receiver does the DTS
decoding as the end result is the same.
Actually, disabling AC3 passthrough in MythMusic would allow the
visualizations to work with DD/DTS content. However, it seems that nothing
gets passed to the visualisation at all with multichannel audio - it just
flatlines (this can be replicated with any 5.1 FLAC from my test suite).
Let me know if you think I should raise a different ticket for that one.
Oh, and thanks for looking into it. It's in a much better state now :)
P.S. PulseAudio - Not even once. alsa:hdmi all the way.
