[Windows] AudioEngine testers - Windows platform only

**DDDamian** · 2012-04-02 23:28

@HeresJohnny - that error is coming from Windows - according to MSDN (Microsoft Developer Network) it occurs when:

Code:

The method failed to create the audio endpoint for the render or the capture device. This can occur if the audio endpoint device has been unplugged, or the audio hardware or associated hardware resources have been reconfigured, disabled, removed, or otherwise made unavailable for use.

I typically have noticed it if WASAPI is not actually in Exclusive Mode - can you check your Windows audio properties and ensure that in the last tab (Advanced) the two checkboxes are both ticked? "Allow applications to take exclusive control of this device" and "Give exclusive mode applications priority"?

Windows volume must be at 100% in this mode, and any enhancements in that tab turned off. All of these are required for WASAPI bitstreaming to work.

Thanks! Just to clarify, it's not a problem of 96/24 dts on the NVIDIA ION platform, but any DTS will fail at this time.

Thx - think I found the issue to both DTS on your ION (AE uses a more descriptive and newer WAVEFORMATEX_IEC61937 header as opposed to the older WAVEFORMATEXTENSIBLE header, but may not be as compatible) and the double sink opening glitch I referenced earlier - should have another build up in the next day or two - stay tuned!

Anyone else got feedback (with logs if a bug) on their systems and this build? What works, what doesn't, what hardware?

If anyone else can chime in on the sync it would be great (as well as any other comments good or bad)

I've experienced the 24hz av sync issue on all builds I've tried previously, I used to make do by adding a 250ms delay. However in the latest AE build the sync appears to be perfect as far as I can tell. I've tried DD, DTS, DTS-HD MA & TrueHD and so far so good.

As for hardware I'm running:
AMD A6-3500
ASRock A75M-ITX
4GB memory

Thanks so much for your hard work on this, I'm sure it will be appreciated by many!! Big Grin

Really looking forward to it! Hopefully updated from master and with double sink fix!! Big Grin

Good man.

DDDamian, could you find any hints in my log file that might be in relation to the "switching bug"?

Maybe I just have to buy a different amp... Rolleyes

Hey Chris - yep, I think that what I'm calling the "double-opening" glitch is the root cause - it appears that some receivers are more affected by that and I believe it's just setting up a loop. So some ride through it, others kick it out and force a re-open which just re-starts the issue.

I'm hoping that's the case (it's just a logical extension as I can't reproduce on mine) but I have a good feeling that's the problem.

Almost done latest tweaks - should be able to up a new build after some testing tonight or tomorrow!

I will be off for a short vacation over easter. I'm gonna leave in about 24 hours, but tonight I could
still do a little testing if you put on the new build. If not, I will test it next monday.

Thanks again for your work,

Chris
