Thanks, we'll look at it. @gkkpch what do you think?
Yes, I saw that last Friday. It's already done in our volumio version of the tinkerboard kernel. (This is temporary solutuion, we will eventually change this back to the official Asus after Michelangelo and I have tested & verified the Rockchip fix for the sampling frequency issue. As this will take a while, we will update our own kernel so a new Image can be built (approx. 2 weeks from now)
Per backport in Tinkerboard's debian kernel repo. Request to update the fix into Volumio tinker board image as well

Eliminate noise at the start of DSD playback. ALSA: usb-audio: Eliminate noise at the start of DSD playback. Copy mainline DSD playback pop noise fix
torvalds@0120073#diff-cc9fc192670bbec31122ad6874641755
[Problem] In some USB DACs, a terrible pop noise comes to be heard at the start of DSD playback (in the following situations).
[Cause] At the start of playback, there is a little silence. The silence bit pattern "0x69" is required on DSD mode, but it is not like that.
[Solution] This patch adds DSD silence pattern to the endpoint settings.
