As I wrote in my previous post I already managed to use windows driver. But it did not work as I wrote.
But ok, I did another try different way.
I switched off DAC, uninstalled everything from RME - Digicheck, USB driver - it was 6x in installed programs, 3 was possible to uninstall, 3 oldest versions not possible to uninstall.
Rebooted. In Device Manager show hidden devices. Uninstall all RME devices again.
I checked all files in filesystem with rme in name. Nothing found.
Rebooted again. Checked Device manager hidden devices - no RME. That is correct.
Switched on DAC. MS USB 2.0 driver installed for AD-2 DAC, 1 unknown device - probably SPDIF input which has no driver installed.
Tested windows device Analog12 - it played, possible to set target SR for mixer to 32/* up to 384kHz.
Tried to play from Foobar latest version. No DSP or other plugins.
WASAPI all possibilities - does not work - unsupported device format.
Default windows output via mixer worked.
After switching Foobar output from 24bit to 32 bit because I saw in windows sound device setting there are only 32bit sample rates.
16/44, 24-44, 24-88 worked with no problem.
24-48, 24-96 and anything higher including all DSD did not work - SR was switched correctly but sound was interrupted several time per second like there is small buffer or something like that. When switched from WASAPI event to push it was even worse.
Interesting that 24/44 worked, 24-48 not, 24-88 again worked
Then I tried MusicBee - all PCM SR worked, but DSD was resampled to PCM.
Tidal with force volumes and exclusive - everything was output in 384kHz which is set in windows settings, no SR switching, looks like going via mixer.
Windows 10 v2020 with latest updates, Intel NUC 10 gen 6 cores 12 threads up to 4.7GHz and 16GB RAM.
So I spent again several hours today to make MS WDM correctly working with DAC but it was again waste of time as usual.
The only possibility is to use RME ASIO, this is the only thing which really works and use WDM for other players with bad windows resampling.
I regret users who do not have enough sw experience, it must be pain to try to solve it for them.
