Hi to all.

I wanto to use my Microsoft Surface Pro as a multimedia player with some high definition video and audio files.

This is my system:

Microsoft Surface Pro -> Mini Displayport to HDMI adapter -> Kenwood 5.1 Home Theatre receiver -> TV

I've configured XBMC to use WASAPI and enabled audio passthrough.

Well, if I open a video file with a dts audio track my recevier show that the audio source is dts and all work well.
If I open a .dts or .wav audio file with a dts stream, i can't hear nothing.

I've caught XBMC trace and there seems to be an error opening WASAPI only whith .dts files, even if the audio streams are similar in both cases.


Trace for working passthrough:

Any ideas?

Seems relevant.

Don't post log snippets as the full debug log is always required, and don't post logs directly into the forum, instead use either http://pastebin.com or http://xbmclogs.com

A sample file so others can test would also be useful.

@madjockxbmc: thank you, i had already read that post but I ahen't found a solution.

@jjd-uk: sorry, I skimmed log file leaving only the significant rows. Here are th full Logs:

working stream: http://pastebin.com/SkLSG7Vy
error stream: http://pastebin.com/qNh2Axs7
here's a dts audio file: http://www.diatonis.com/downloads/diaton...et-her.zip

As showed, audio streams are both recognized by XBMC gotham but when it try to play the audio file, WASAPI initialization failed.
With my old machine having the Frodo release installed, the same files plays good with passthrugh.

Just tried that sample on my systems, it works on both my main rig with passthrough to AVR and also on my test rig decoding to PCM and connected direct to TV, therefore there's an issue with your system.

Your HDMI connection to the AVR is capable of PCM 5.1 so try deselecting the "DTS capable receiver" option to see if the DTS audio can be decoded to PCM, then if still issues then try setting "Output configuration" to "Fixed" and set "Limit sampling rate" to "48.0khz". For reason for this is that the playing DTS and non-playing DTS has different sample rates, the one from the mkv is 48kHz and the problematic one is 44.1kHz, it maybe an issue with 44.1khz on your system.

The other option to ttry is see if there's any different in how it is handled by the default music player "PAPlayer" and the video player "DVDPlayer", do this by opening Context menu with file selected, going to "Play using..." and selecting "DVDPlayer".

Ok, opening the dts file with "DVDPlayer" instead of "PAPlayer" did not change anything..

But I found a .dts audio file with 48.0KHz and it's played well !!

So I think there's something wrong with my Intel HD driver...

Surface Pro come out with Microsoft Video adn Audio Drivers.

I've installed:
- Intel HD graphics Driver [https://downloadcenter.intel.com/Detail_...ldID=23885]
- Realtek High Definition Audio Driver R2.75 [http://www.realtek.com.tw/downloads/down...Down=false]

After installing both Drivers the problem still persist...
