Amazon music player and MC30

I got Amazon music playing using the WDM device to 4 x DSD as well as upsampling - as separate configs, it does sound very good in my setup. The problem I have now though is the sound lag for gaming, it's very bad, I've not tried other sources but I suspect there would be lip sync issues. I've tried adjusting my ASIO buffers to the point I got sound issues. I'm suspecting this is just what happens with layers of upsampling / DSP in between the source sound and the output to the DAC ?

If you're doing a conversion from PCM to 4xDSD (DSD512) on-the-fly while using the WDM driver there's going to be issues with latency for sure, it takes a lot of resources to do the PCM to DSD conversion. So I'd say it's to be expected unfortunately.
Maybe avoid doing the PCM to DSD conversion completely? It's a lossy conversion and there's no actual, real benefit doing so. That might improve latency when using the WDM driver or it may not (it's hard to say), otherwise in my opinion doing the PCM to DSD conversion is a waste of resources.

Only problem is the Windows mixer will be upsampling the 48kHz original to 192kHz before it gets near the WDM driver and MC DSP then upsamples it again from 192kHz to 768kHz. I didn't try re-encoding to DSD as that would have meant no EQ.

How do you go about setting the Amazon to play through the WDM driver? That's what I want also but haven't been able to figure it out. On my laptop (Win 11) it keeps bypassing my Output choices and plays back just the same as from their website (or app).

Take a look at the WDM topic on the wiki. Set it up and test playback through MC from a browser before you set up Amazon.

What I have found to work *extremely* well is to go to the DSP Studio / Output Format and select [DSD in DoP Format] and from the Playback Options mark [Memory Playback] [Load Decoded File Into Memory]. Never saw a need for increasing the DSD resolution, the DSD64 is plenty good and with fewer hickups.
