But wait, there's more!
I don't have any DSD tracks other than the test tracks I downloaded from 2L.no, etc., and I have not really tested DSD playback since a year ago.
[the following has been edited since the original post]
Things seem to have changed---moOde has advanced considerably and I updated the KTB firmware perhaps 6 months ago. (Easily noticeable became it now presents its name as "Tone1 " instead of "Khadas Tone Control "; the card id is "Tone1" without the trailing space)
Now: moOde 7.2.1 (fresh install), RPi4B, KTB Tone1 DAC.
When I play tracks with Software or Hardware Volume Control selected in MPD config settings:
PCM
- Software VC: normal playback. I have control over volume using the moOde knob in either mode.
- Hardware VC: same
DSD
- Software VC: normal playback. No volume at 0 then 100 percent at any setting from 01 to 100 (just as Tim reports below for his Allo Rev).
- Hardware VC: abnormal playback. I get burbly white noise diminishing in volume as I change moOde Volume from 01 to 99 and then clear playback at 100.
ISTR this is what I used to get with software VC back in the old days (but I'm old so...).
So I'm shipwrecked on Clueless Island. Sorry, I'm not in a position to do detailed testing.
Regards,
Kent
