DSD over PCM (DoP) sound ticks

Origin
1

Hello!

I nave Topping D10s DAC connected through USB to my MacBook Air M1 with macOS Monterey and Audirvana Origin 1.0.3.
The problem is: when I trying to play any DSD files (64 or 128) using DSD over PCM 1.0 or 1.1 method, sometimes I hear ticks in sound (like when you listen vinyl and hear needle ticks). When I use Convert to PCM methods, the same files sounds good.
How to fix this problem, does anybody know? I want to listen DSD files :slight_smile:

Try to reduce pre-load cache to 4000MB.

I experienced similar problems on topping D3+ pro while playing DSD on M1 macmini. But now I switched to S.M. S.L M500 and problem gone DSD plays no problem. So I guess is a dac problem rather than M1.

4

How to do it?

5

Found, not helped.

6

Try with “convert to PCM” option, just to confirm that it’s not a throughput problem.

7

I tried. “convert to PCM” sounds great, no any problem.
Also, when selecting “DSD over PCM”, there is a quiet noise (tshsssssss) for all tracks. With “convert to PCM” no such noise.

8

Well, the only remaining thing that comes to mind is to check if there is a newer firmware for your DAC. Beyond that, there’s not much you can do.

9

FWIW, this does not happen with my two DACs. Sounds like this could be isolated to your particular DAC unfortunately.

Updating firmware is a good suggestion by bitracer.

One more interesting question: why sound level on DSD much higher than on PCM? All filters disabled.

There’s 6dB boost option you can toggle in the settings.

12

This option is available only for convert to PCM option. But I want to decrease the level for DSD, because it seems to me (based on what I hear on very expression scenes), that DSD sound level is too high (over high).

13

Ahh sorry, I thought you were still converting to PCM.
