Hello all,

Have a new integrated amp, Denon PMA30, capable of 24/192Khz. Having a little play about, but cannot get windows to output more than 24/96khz.

I'm outputting via optical, but from reading, this cannot support 24/192 and you need to use COAX. But my mobo doesn't have coax out.

Motherboard says it can do 38/384khz
 
While optical would have far more bandwidth than any copper, S/PDIF standard is simply from IT stone age.
Mobo having coax output (using RCA connector) would make no difference to that limitation being only electrical signaling (galvanically not isolated) version of same standard.

Anyway unless you're bat, there's absolutely zero use for 192 kHz.
 
Yeah, I wouldn't expect to hear a difference, just playing with what my hardware can do and understanding things
 
Just tested it on my system which is connected using TOSLINK. 192KHz/24bit output works perfectly.

The marantz AV7701 receiving end confirms. Optical seems to work just fine for this.
 
I'm running 24/192 optical with a Cambridge DacMagic+. I'd imagine the 24/192 may only be possible via USB? My mobo has different limits for USB and optical, think I only got 96 with USB connection...

And no, you probably wouldn't hear a difference anyway. I'm a hifi nerd, and I can't...
 
I'll have to try and find my mobo limits, somehow it should put out 38/384, but perhaps only via usb. My Denon doesn't have usb in though, only the more expensive one does.
 
Well can't find it out at all lol.
Put latest realtek audio drivers on, no change.
My brothers pc and even my old work pc and both do 24/192.
All I want to know is why lol

Edit - speaker out does 32bit/96Khz
Optical out only 24bit/96khz
I guess USB audio might do the 32/284Khz

At least I know now, phew.......

All (or most) newer SoundBlaster cards were upgraded to do 24/192 over Optical, my ZxR is 24/96 so you would need look at your Mobo manual.
 
Use the USB output - Optical typically only supports up to 24/96 ( quality of toslink cable actually isn't too great so 24/96 tends to be the default) - Coax tends to support up to 24/192 - USB on windows 10 supports up to 32/384 with USB Audio Class 2.0 -That should work (I use it myself feeding via USB to a Chord 2Qute DAC

Remember to use WASAPI (a kind of direct Windows interface to the audio device) or ASIO for feeding the digital signal out of the PC - if you use direct sound it uses the window mixer and that only outputs at 24/48 Hz
