Fiio K3. DSD over PCM problem

Post by fiftydinar » Tue Jul 27, 2021 4:15 pm

Hello,

When I enable DSD over PCM in DSD128 or DSD64 format, the only thing I hear is the high frequency noise.
Fiio itself claims that Fiio K3 supports native DSD256 so I don't see why it wouldn't work properly.

Configuration & settings:
I use Windows 10 version with:
enabled Exclusive Access, Oversampling to x16 (realisticly x8), Dither enabled with Noise shaping, 64bit audio processing, Audiophile resampling & Parametric EQ enabled with 10 bands.

I usually play 44.1 & 48KHz FLAC files.

Perhaps I need to tweak some settings?

Also other quick queston:
What is MODE: Event in Exclusive Access, what it does & should I enable that too?

Thanks.

FiiO says their USB audio driver is required for USB Audio Class 2 (includes decoding up to DSD256), whereas without USB audio driver, USB DAC functionality is plug and play with decoding/output limited to 24bit/96kHz PCM

The thing is, I use their latest USB driver with the USB 2.0 switch.

Update, I disabled Oversampling, than enabled All to DSD, now it works. I also reenabled Oversampling after that and it works too.
