How to play 24bit-192khz FLAC using USB to DAC?

You have to downsample it to 96kHz or less.

192kHz over USB can't be done from what I know.  Perhaps in the future.

 

Edit: fix'd, lol

At least E-MU 0404 USB can do that.

 

USB 2.0 Hi-Speed
			- Full 24-bit resolution at all sample rates - 4in/4 out channels from 44.1-96kHz - 2 in/2 out channels from 176.4-192kHz

If there isn't a dedicated WDM driver available for the DAC model then, it's possible that the Asio4All uses some generic one which does not support higher samplerates than 96kHz (isn't the Asio4All a WDM wrapper 'driver' ?).  

 

Have you tried if 192kHz works w/o Asio4all (Direct Sound or Primary sound driver (set the DAC become default output device) in Foobar (or Null output))?

Doesn't 192kHz work in other software either (try as WAV as well) (Qtime, etc.)?

The Microsoft Windows usb driver only supports up to 96k. If you want higher, you need a custom driver. These are usually supplied by the soundcard or dac maker if their product will play higher than 96k. It's possible your dac (like mine) only supports 192k from the coax/toslink (s/pdif) input and is limited to the native <=96k speed thru usb. ASIO4ALL bypasses some layers of windows, but still uses the standard usb driver. One way around this situation is to get a usb to s/pdif converter (transport).

Yeah. You don't give the make or model of your DAC but like people have said if it uses the class compliant (generic windows) drivers it will not do 192.

 

You could try the manufacturers website and see if there is a suitable driver available but in general 'audiophile' grade devices don't supply bespoke software. It's cheaper and writing software isn't a core competency.

 

Most pro-am grade audio interfaces (Focusrite, E-MU, MOTU, RME, TC-Konnekt, Presonus etc etc) will handle multiple channel 192 no problem. Along with many other real world advantages not least ultra low latency. These devices are often used with Digital Audio Workstation (DAW) or other sophisticated audio programs and the manufacturers supply bespoke drivers as a matter of course. You pay extra for better supported drivers - RME has the best reputation - but these devices offer extremely good value for money compared to 'audiophile' grade equivalents so it's not a problem.

Another option is to use a USB to coax like the m2tech hiface. Goes to 192 but does use a custom driver. Many USB chips are sourced by TI and tenor and stop at 48k or go to 96 but don't support 88. Going to coax a) allows all frequencies over spdif with fewer caveats, to the limit of most dac inputs.
