Hi there,
I just found this post:
https://tango.0pointer.de/pipermail/pulseaudio-discuss/2011-March/009291.html
Is this relevant to HDMI passthrough to receivers IE: so the NVIDIA
isn't decoding the audio stream, allowing the receiver to get DTS-HD MA,
True HD, FLAC etc encoded streams and do the decoding on the receiver??
Because at the moment I only get PCM on my receiver from the NVIDIA,
where as in Windows 7 I can use powerdvd which passes through the signal
for the receiver to decode, in Ubuntu I have no options to do that.
The a52 sink is not in Ubuntu for patent reasons [1], but that's only
about encoding.
Passthrough is, unless Arun corrects me, about having already compressed
data being decoded in the receiver. Ubuntu 11.10's pulseaudio has
support for that, but the rest of the pieces aren't there - in
particular, no client application supports PulseAudio's passthrough API
yet.
