The Xonar Essence STX Q/A, tweaking, impressions thread
Feb 15, 2012 at 1:57 PM Post #2,956 of 5,721
I'm still having issues with 88.2 KHz files. I'm running what I think are the latest drivers (7.12.8.1794) : Foobar WASAPI -> STX. It always crashes with any 88.2 KHz file.

Does anyone have any ideas about what's causing this? I was under the impression that this issue had been fixed a while back with a driver update.

Cheers

Alright then.

Thanks for the clarification and the help. I'm a total no-nothing when it comes to WASAPI and ASIO. I'll just run it as ASIO to avoid unrecoverable playback errors.

Cheers

Yeah, those resolutions where added later with the update of the ASIO driver...IIRC.
Just use ASIO and all should be good.
 
Glad I could help.

Sorry I didn't see your post edit: I'm not sure I have any 176.4 material to test it with.

I've never used ASIO before but it seems to work just as well. The only thing I notice is that if I set the buffer length too short I hear a background ticking noise.



Now I just have to track down and eliminate the perpetual, ongoing bane of my computer experience - coil whine.

It doesn't matter, IIRC both those resolutions are only available through ASIO.  You can test with WASAPI if you want but you will probably just get the same crash.
ASIO is very similar to WASAPI in the way it operates.
You don't need a really low buffer just set it as low as you can without any negative effects.  That's the way most people I know set the buffer.
Good luck.

MusicBee outputs both 88.2 and 176.4 through WASAPI (configured not to resample) to a D2X using Unixonar 1.51. On the Same computer Foobar gives an error playing the same thorugh WASAPI 2.1 plugin.
I tried on a friend's PC J River MC 17 with an Asus ST and both WASAPI and WASAPI Event Style could play perfectly those resolutions whereas Foobar, again, couldn't giving the same error.
Looks like not all WASAPI outs are created equal.

Yes, I use 88.2 and 176 via Wasapi and KS through the ST with no problems using JRMC and unixonar drivers.
 
Here's a question though: if the ST/X analog out has controllable volume (and not bypassable as far as I know), then
analog out can't be bitperfect, right? 
 
Also I thought I read that 88.2 and 176 were downsampled from 96/192...

That's what I was wondering as well.  I thought Xonar did not have 2 separate clocks for both 88.2/176.4 AND 96/192, thus only natively supporting the latter.  If firmware update "fixed" the 88.2/176.4 support, are they just using the one clock they have and resampling?

What firmware update??? I don't think the ST or the STX are firmware updatable.
 
Many sound cards and USB DACs have a single clock and synthesize both frequency families (44.1 & 48) from it.
 
Funnily I have a problem with ASIO and 88.2 & 176.4KHz files, if I play any cuh material first I only get noise but if then I play for a couple of seconds a 96 or 192KHz file and return to the former it then plays fine, as if the PLLs had got stuck and needed a little push to start going again. Don't know if I got a faulty ST or if this is a common issue. I have another Xonar (D2X) which doesn't suffer from this using excatly the same drivers and player/OS configuration.

ASIO should bypass the volume and any effects at the card itself.
