There is no loss of quality over the USB connection. However, there is (or may be) on the way from XBMC through the OS stack onto the sound card, which can be avoided in different ways, one of them being ASIO. What I want to know is if and how XBMC already tries to achieve this, and how this possibly will change in the future through the AE effort that this thread is about..

WASPI is how I'd roll for bitperfect reproduction through a high quality DAC. If you're getting distortion, I'd point blame at the DAC's drivers.

In DTS Audio files (.wav), It looks like the speakers are not mapped correctly.
I get what seems to be the LFE channel in the rear left speaker...
Can anyone confirm this ?
(receiver is Onkyo 807 and shows "Multich", HTPC is ASROCK Vision 3D with Ubuntu Natty)
I checked using test files from here : http://jkft.info/xbmc/testfiles/channelid/Audio/
In all the 6 channels files + .dts + .ac3 (didn't try 8 channels),
It confirms that there is a problem with speaker mappings :
Front Left channel -> Front Left speaker
Front Right channel -> Front Right speaker
Center channel -> Center speaker
Rear Left channel -> Rear Right speaker
Rear Right channel -> Subwoofer (barely audible)
Subwoofer (LFE) channel -> Rear Left speaker
Do anyone else has this ? please check the test files

@nirmv, and EVERYONE ELSE testing with PAPlayer (audio), its incomplete, channel re-ordering is broken there for the current time. If anyone would like to fix this... see the warning in the log about GuessChLayout and go from there. If not, just wait .

Just started testing this version. Just did a build for windows. I thought I had everything setup. I have a 7.1 audio system, was testing with two different files that both had dts-hd in them. I set the output to HDMI, and turned it on exclusive mode and changed the speakers to 7.1. I get no audio when I play either file, and the video playback is all jumpy. If I turn the output device to analog, or spdif I get audio, but on my receiver it just says DTS, no dts-hd.
Am I doing something wrong in the setup here, or is it not outputing actual dts-hd yet? I figured it would need to be set to HDMI to get that, but like I stated, on that setting I get no audio.
Oh, am using a Nvidia GT430....

Is anyone testing AE with a Yamaha receiver? I tested my system as per the thread on NVNews and got a positive result. I would be very interested to see if any other Yamaha users have had success.
Here's a my debug.log
Checking ALSA hw_params shows something happening but the AVR reports 'No Signal'
When playing video with AE, normal DTS/DD passthrough is working fine, but DTS-HD and TrueHD produce no sound.
Sometimes I get smooth video playback and sometimes I get choppy video playback. When I do get choppy playback, I get a lot underrun errors. I'm wondering if the
I'm using a an Atom 525 based HTPC with an ION2 (GT218) GPU, Ubuntu 10.04, kernel 2.6.38-10-generic, latest ALSA 1.0.24 from git.
Thanks and hope I'm not making noise in this thread.

Sorry if this question is answered elsewhere, I did search -
The AE branch - is it based on dharma 10.1 (i.e. the point at which the branch was taken), plus AE specific changes ? Or is the branch constantly updated from trunk ?
And likewise, is trunk updated periodically with changes from AE branch ?

AE branch is just a export of some way older xbmc GIT revision newer than Dharma older WAY older than current, that is not been updated in a long time even if AE code has the revision of xbmc has been left in dust.
I imgine the idea is to mege AE into master by eden release or xmas time or new year as is around the time xbmc comes out marked as stable and outed.
