Hi @kennyb123 - I too have noted issues when using “Roon server with HQPlayer” with my CX / EX combo, specific to DSD upsampling, (no problems apparent with PCM upsampling). DSD Upsampling has been the primary setup and best sounding in my system, with minringFIR-lp as the filter I always used prior to AMSv5. It worked great in v4.4, but since v5 there have been issues with DSD playback. I’ve shared the below details via email dialogue with @MarkCole but I know the Antipodes team has got their hands full at the moment.
The CPU Usage in my case for DSD upsampling is about 10 - 15% higher than with v4.4, (hovering around 60-70-%), and the Core Temp is higher as well by 10-15 degrees vs v4.4. I’ve stopped upsampling to DSD until further notice.
Issue description:
When using HQPlayer with Roon Server, and with Roon set to DSD Conversion, the final signal rate output is actually PCM according to what is displayed in Roon and on my DAC…
With the Sample Rate Conversion set to DSD it seems to my ears that either: (A) the final output is actually DSD but what is being displayed in Roon and on my DAC is the PCM setting from HQPlayer… or, (B) it literally is converting to DSD but then a final added output conversion step to PCM is happening (which is being displayed as such in Roon and on my DAC).
I’ve included some screenshots with details labelled to provide added context for:
- HQPlayer Settings - PCM vs DSD
- Roon Signal Path - Sample Rate Conversion set to DSD
- Roon Signal Path - Sample Rate Conversion set to Max PCM rate
