I have a surround receiver that can handle AC3 sound, but not DTS through optical. I understand that XBMC (release candidate 2 frodo) should be able to transcode these files to AC3 without a problem, however, depending on settings, things don't work.
With audio output set to Optical/Coax, And AC3 capable receiver ticked, I get 2.0 sound from files in other codecs. This is the same if the output is set to HDMI.
However if i tick LPCM capable receiver with HDMI selected as well, i get the two surround channels coming from the front speakers and no other sound.
Everything works fine for AC3 files.
Is there a setting in mac os that could change this. The optical cable is connected to the mac using a 3.5 mm toslink adapter if that makes a difference.
Thanks

transcoding from dts/aac to ac3 is broken currently in the new audio engine. We are not able to quick fix this for frodo - we aim 12.1 for this.

I'm unaware that optical can officially handle anything but two channels of audio which includes the fake that allows passthrough of ac3/dts.

It's during the intermediate stage between the decoding to PCM (gets forced to 2.0) and then re-encoding to AC3. Ends up as AC3 2.0 final output.

Both can be safely reverted IMHO.

If this fixes the 1h02min slowdown effect i'd get a laugh flash...
The real fix would be that we need to know if we are ending up in an 2.0 encoded format or not. If not - we need to clamp to 2.0 - if we do - no clamp needed and we would allow the intermediate lpcm state with > 2 channels.
DDDamian - any clue how this detection could be done? (basically we would need to detect the transcoding use case).
