Hi Peter,

I recently bought a RME ADI-2 FS Dac, because it had great reviews. It is a 32Bit 768KHz DAC)
It has no possibility for the use of Kernel streaming. However I CAN play music via XXHe, but only 16 Bit files, not higher. And only then when I switch off the fx button and leave the Output Sample Rate slider in the left corner (in the Settings I choose: Analog (1+2)(RME ADI-2 DAC))
3 Questions:
- How come Foobar2000 gives me no problem at all in playing all sorts of files, thus also 24Bit files?
- How can I activate WASAPI again? By choosing Engine#3, yes, but how?
- If I want to leave the settings mainly as like now (thus Kernel), what do I have to do to be able to play 24Bit and 32 Bit (and why can't I use the Upsample Slider?)
Best Regards, HW

Hey RW,

My first advice would be : bring it back. It seems that it will hunt you with oddities forever. Additionally, I think (not sure !) there's some Chinese XMos driver in order and they don't shine for "compatibility". Tweaking, yes (you won't like that).

https://www.forum.rme-audio.de/viewtopic.php?id=26980
Reading through that, tells me enough. Do notice that the most "severe" problem is the sampling rate which won't change automatically, which is why you probably won't understand what is happening. I did not sort it out, but think like : always first set the sampling rate in the control panel (be sure it took the change) and then next start playback which matches that sampling rate. And 384 is max, as it seems.

The fact that Foobar works does not tell a thing because it can work with WDM and as far as I recall also in non-exclusive mode (the good old not bit perfect resampling mode). Read : In Foobar it still does not work, but you don't notice that the used sampling rate is different from what you "set".

Summarised, to me (and at first glance) it looks that the RME is too much of a Pro device (using ASIO and everything works).

Lat thing : A DAC which does not support Kernel Streaming does not exist in my book. So this could be a matter of installing the proper driver. Maybe you can ask on that forum.

With changing the 24 bit / 32 bit setting you may see some success suddenly more success (see screenshot below, the DAC Needs section).

WASAPI is available when you did not shut off the WASAPI Services. See second screenshot.

I hope you can get it done, but remember, it will always annoy you because the sampling rate won't change automatically.

Kind regards,
Peter

Thanks, Peter. I already pulled all the handlesl and pushed all the buttons, but nothing worked properly. Also the latest drivers were installed
 The DAC is sent back
