[WINDOWS][PATCH]Bitstream output of HD audio formats

(2012-04-28 21:41)Streamerke Wrote:  Unfortunately this is not working at all for me...

I have an Onkyo TX-SR707 capable of every HD audio format and this was already proven with my Popcorn Hour player. I have played movies with DTS-HD MA and TrueHD.

Unfortunately when I enable the addtional settings supplied by the patch then I get a movie in slow motion and no sound as soon as I run a movie with TrueHD or DTS MA. At the bottom the error message "Failed to initialize audio device - Please check your settings".

I have the same Onkyo unit, no issues. I've seen that message before a long time ago, though. I can't remember exactly, but I think I didn't have the HDMI output on the HTPC enabled through Windows. Setting it as default didn't make a difference for me, as XBMC will allow me to choose the HDMI output so long as it is enabled.

Oh, and if you have an ION GPU or GeForce 9400/9300, you're out of luck.
Anyway, perhaps of no help, just chiming in.

Have you update your GPU driver? Did you select the proper HDMI audio output in Windows 7 control panel? Did you select the proper HDMI audio output and select "WASAPI: Onkyo (High Definition audio......)" in XBMC settings/system/audio output? Did you enable DXVA2 and select DXVA as Render Method in XBMC settings/video/playback?

I have the latest GPU driver installed. Yes I have the correct HDMI output in my VISTA control panel. Yes I did choose the correct HDMI output in XBMC. When I play a TrueHD movie and I unflag the setting "TrueHD capable receiver" then I do get output.

No I did not enable DXVA2 as it creates problems on playback of some of my content.

I'll do a test again tomorrow to make sure I try all possible settings and I'll come back after that. Thanks for your help so far!

You need to make sure that you selected "WASAPI: TX-SR707 (High Definition audio......)" in XBMC settings/system/audio output

After you selected DXVA2, did you selected DXVA as Render Method in XBMC settings/video/playback and disable everything else in it?

If the video playback is unstable, you can disable "Use fullscreen window rather than a true fullscreen" in XBMC settings/system/video output....

Not 100% convinced that HD Audio bitstreaming works with Vista. Unflagging the setting, provides decoding by xbmc with the LPCM track being passed to your receiver (the exact same output, just not bitstream and won't light up your receiver to show TrueHD). Unchecking the DTS option should provide similar results but on DTS core sound only.

Vista SP1 can bitstream as it supports Wasapi exclusive mode. Sounds like the GPU is the limitation if your settings are otherwise good.

I used to be able to bitstream HD audio with my previouse Vista machine....

Bow to your superior knowledge - seem to recall having an awful time with Vista and a 5450 card and never quite managing to get it to work.

However I don't think the poster has enlightened us to the rest of his hardware - only that he has a receiver which supports bitstreaming, so your assumption is likely correct that it is a limitation of his GPU.

Hi DanielaE

I noticed you're using the AMD Fusion E-350 platform... me too, I have an Asus E35M1-I DELUXE.

I've had success bitstreaming HD audio with both your patched XBMC and also XBMC AE.
I see you have tested with both Realtek HDMI Audio driver and AMD Catalyst HDMI audio driver.
Is there any benefit with using the Realtek HDMI Audio driver over the Catalyst driver?
Also are there any XBMC settings that are recommended to be used with the E-350 platform?

I'm running Win 7 x64 with AMD Catalyst 12.4 drivers.

Thanks

Jerry
PS Thanks for the great patch!

First of all I must say this is a great patch, I have been using the HDAudio patch for a month now and it has been flawless!

However I ran in to a problem today when I received my pulseeight cec adapter which doesn't work with xbmc's official builds (at least not when you have a receiver between the tv and the htpc).

would be awesome if the cec patch could be integrated into these builds
https://github.com/xbmc/xbmc/pull/887

otherwise I think I will have to live without the cec adapter until XBMC official builds get the HD audio working, which seems to take a while...
