Moving the settings file worked. Thanks!!

I recently installed updates for my Windows 11 home OS on my MSI PC and downloaded the 5.7.4 desktop software. Now, when I try to start up desktop, nothing happens. I tried restarting and reinstalling HQPlayer desktop. I have been running the previous version of desktop for many months and it has been quite stable. Has anyone faced this issue or can suggest a fix?

No I am running HQPlayer on a windows PC with a Nvidia GPU playing to the DAC through a NAA running on raspberry pi. Input is from another computer (Mac) running Roon. And DSD works fine. It is PCM that is not working. Which is strange and the first time I am having this kind of an issue.

Interestingly, if I set the default output to SDM, but set SDM pack to none instead of DOP so that the DAC (which needs DOP) will fail with DSD and revert to PCM, then PCM plays fine.

I am having a strange problem. I am able to play DSD256 with sincMx filter and ASDMEC5-super on my windows machine to an RME-ADI 2 DAC. However, when I switch HQPlayer to PCM I get a ton of interruptions. I thought DSD was the much harder processing challenge. Any ideas on why PCM fails like this while DSD works fine?

I tried the software on my Mac and tried it with audio routes to HQPlayer with Blackhole. It does change the sample rate but HQPlayer remains at whatever rate I started playing it at. Is there anyway for HQPlayer to detect the input stream and adapt?

Do modulator settings matter when upsampling to DSD with ESS DACs since these DACs seem to be remodulating the input DSD signal anyway?

Should have also mentioned that it is the one with the AKM4493 chip.

The DAC is the RME ADI-2 FS. I am able to play 48k DSD fine with the sinc-M filter. But not the since-L of sinc-Mx filters. When I play 48k DSD, it shows the 12.288M sample rate and the music sounds good. Except for the dropouts when I run with the sinc-L or sinc-Mx filter. I am running HQPlayer desktop on an M1 MacBook Pro and I wonder if the rate is too much at 48x256 but is ok at 44.1x256.

Thanks for sharing your observations. The DAC I am using is capable of doing 48k DSD. So, when it is upsampling 48/96/192 kHz tracks, it is using using 48x256 = 12.288 MHz rate for DSD. However, based on your comment above, I tested 176.4 kHz going to DSD 256 and I didn't have any issues. But, when I try 48/96/192 kHz I am getting drop outs. But, since this is also doing integer upsampling, I am even more confused why this is the case.

sinc-Mx is 16M taps when converting 44.1 to DSD256. Is it also 16M taps when converting 176.4 kbps to DSD256? Or is it four times lower number of taps, I.e., 4M taps? Reason I ask is that I can run sinc-Mx with ASDMECv2 at DSD256 when converting 44.1 file but get dropouts when converting 88.2/96 or 176.4/192 files.

Thanks for posting these curves. What would be the benefit of using the 150 kHz filter instead of the 50 kHz filter since it lets in more noise? Is it better phase accuracy in 20-20 kHz? Also, how much is the attenuation of the 50 kHz and 150 kHz filters and by what frequency do they achieve this attenuation?
