Lossless sound question (solved)

I've had a little trouble finding what I am looking for in regards to HD sound in linux. XBMC recently updated to 13.0 Git (standard install with Arch stable) and I lost the DTS Master Audio and Dolby True HD because of issues with pulse audio.

I am considering a couple of options here, and would welcome feedback:

1. Convert HD sound formats to flac, but still not clear if I'll get the same sound quality or what settings to use.

2. Get rid of pulseaudio, without getting rid of Gnome

3. Get rid of Gnome altogether, which I am otherwise a big fan of.

4. Find some unknown workaround.

Something else that I found interesting is that even when the receiver shows DTS HD or True HD, when I look at the signal information for audio input it still shows 48,000 kHz. I pay a great deal of attention to sound quality, and I still "think" it is playing in the HD format, but I want to know for sure.

Your issue is a bit odd since XBMC 13 has full pulseaudio support now. Really odd.

I wonder if there is another reason for your problems.

Dramatic Audio Engine Improvements

The Audio Engine introduced with XBMC 12.0 “Frodo” has been reworked to be simpler, faster, with better quality and less likelihood of breaking in XBMC 13 across all platforms. You may also notice that some users will need to reconfigure their audio settings. This is caused by the audio improvements and restructuring of the settings systems. However this should be more intuitive and user friendly than it was in XBMC 12 thanks to improvements in Settings.

On Linux there is additional good news for Desktop users who don’t use XBMC as a standalone HTPC through OpenELEC or XBMCbuntu. XBMC will now cooperate nicely with the pulseaudio server and will provide real pulseaudio support. This is a behavior change, make sure to read the PulseAudio XBMC wiki page to learn more.

I'm not sure then. That link links to this

of.http://wiki.xbmc.org/index.php?title=PulseAudio#PulseAudio_Output_Configuration

which shows passthrough for the HD sound formats disabled with pulseaudio. That was the information that I had been going off of the get the standard definition passthrough working again. Before the update the option for HD passthrough was there, and now I don't see it.

Switched back to XBMC 12-2 and got the HD passthrough working again with no issues. It's not clear to me what the problem was but with this version doesn't have them.
