Thanks PIH - made a note to investigate. Things like that are exactly what we're looking to discover.

Hey dddamian,

Tested on both on an ATI 6450 and NVidia GT 520. I'm not switching refresh rate or syncing to display for those tests.

TrueHD... intermittently hangs for a short while whilst seeking

DTS-HD... intermittently hangs for a short while whilst seeking

FLAC files appear to be ok.

Not sure why but i can't get it to misbehave whilst in debug, so those logs are standard. Hopefully they will be enough.

Believe there's CAESinkWASAPI errors at the seeks.

Cheers Wink

Thx LiquidSkin76 - when you say hangs intermittently on seeks, is that kind of a lag in the audio starting again after the picture starts?

From the log it looks like the sink gets re-initialized with null values for some reason after a seek, but can you just describe what you did and what you saw for me?

When it seeks ok, yes, there is a short lag in the audio coming back, so video starts for a few seconds without audio.

However the hanging is slightly different. Both video and audio hangs for a short while. Can happen on standard short seeks (30 secs) and MKV chapter seeks, however it tends to be intermittent.

Hope that helps.

Thanks for your hard work. Seriously looking forward to AE hitting the nightlies! gnif has worked wonders, and now it's great he has help on the Windows front. Good man!

Cheers Wink

I made some more testing.
The previous test was made on an xbmc installed on top of the Windows Patch version. This time I uninstalled xbmc and checked the field to remove all settings. Then installed the HE version.
This time xmbc behaved much better. There were occasional audio dropouts, but much less frequent.
I still got the crash when Multichannel LPCM capable reciever was unchecked.
Played an mkv file with DTS HD MA which worked fine.
Played some .ts files with recorded HD TV programs, that also worked fine
To use the "scale" to move back and forth in media with non HD audio works fine, but in media with HD audio there are long delays before picture and audio recover and sometimes audio will not come back at all.

@liquidskin - thanks! I'm trying to help gnif out code-wise (especially Windows side, but core where required) and also trying to condense/analyse some of the feedback and suggestions for him so he can stay focused on core issues. Feedback here goes directly to gnif and the team via our internal forums and IRC channel.

PIH - thanks - notes made. The audio drop-outs have been the biggest issue and I believe we have a fix being tested now. As soon as it seems a sure thing I'll post a note here and upload a new build. Also made note of the multi-channel LPCM setting bug to check it out.

Great work so far guys - the more we can find the better for the merge timeline!

Hi all - I have posted a new build to GitHub - use link on first post and look for newest date of XBMC-AE-20120306.zip

Changes:
- merge with Eden RC2 so library is compatible
- included test fix for audio drop-outs
- fix support for stereo up-mix to all channels

Happy testing Wink

Excellent! Big Grin

Will test tonight and report back.

Uninstalled and installed the new version.
Played some media, but this version behaved similar to the old version and there were dropouts when playing DTS HD MA and Dolby True HD.
The logfile is from playing Dolby True HD.

The speaker settings should be 5.1, but I changed to see if 7.1 was better, but there was no difference.
The dropouts are about the timestamp 20:27.

Hi P-I H, couple of questions:

1) is your M drive a local HDD, a USB drive or a network share?

2) do you have "Sync playback to display" enabled? If so, disable it.

Always try capture the full log - debugging should be on from start to finish. If necessary start XBMC, enable debugging, exit (with it enabled), then start XBMC and reproduce the error. Thanks for your test Smile
