Trouble with WDM Realtek digital output

[DruiD]

The important thing is that buffer size must be 256 or 512 or 1024.

WDM Default in VM is 512... so leaving at that...

And you need in windows sound prefs enable exclusive mode and both option in the exclusive area need enable in realtek spdif output. maybe you need reboot, because another program that use sound forbid that WDM switch to exclusive mode.

A bit clearer here please, do you mean ALL your output devices to be configured as exclusive (only), or just A1 (as VM bases of A1), or just the virtual VM input that you set as default sound etc.?? I have 5 output devices, only 1 of them is SPDIF\Optical out (my amp \ gaming headset), rest of the A2-A5 outputs are either analog or USB.

In VM system settings\options
All outputs are showing as correctly open, up to 8 channels, 48khz and except for the RIFT and USB interfaces, are driven by Realtek drivers.

'reviolent' said that uninstalling the "realtek"
application from (control panel > uninstall programs) solves the issue and I can confirm. I just did this and it works to the point that I now have a 512 buffer size with 48000Hz and crystal clear audio that is higher fidelity than normal stereo. I can not tell the difference between the audio I am getting now than using just the realtek driver as the default playback to work around the issue before.

I then used ASUS GRID to reinstall the latest REALTEK driver and it continued to work for a couple minutes but reverted back to the issue itself. Uninstalled the driver/application again and presto! Problem goes away. The only issue is that for things like Dolby Atmos, it wouldn’t/couldn’t recognize any audio devices without having the driver installed.

The short; REALTEK DRIVER seems to be the issue. Whether it’s a communication issue between VMB and Realtek I couldn’t say. Just my .02.

Very interested in these "hacked" realtek drivers that a) seem to work b) provide dolby live and DTS Etc.
