There is great support from Domenico, just wait and see (no intention to advertise, no need anyway)

Have added my name to the GB3.
Hope it is not too late.

added myself too for one USB to I2S

Driver 1.0.56 fixes the channel mapping for DSD
I am using firmware prior to September 18

RL channels are correct for:

Direct Sound (PCM)
Wasapi (PCM)
foo_dsd_asio (PCM, DSD)

No need to invert the channels with a custom channel map

DSD64 is fine, either native or converted with foo_dsd_asio.
With foo_dsd_asio cannot get DSD128 work.
Also I have some problem with 32/384.

Both DSD64 and DSD128 works in my setup. However, I can't lock to 384K (could be the reclocking)

I don't believe you spoke too soon as I have been finding it difficult to get consistency in results?

what firmware have you got in fifo? or you mean your point to point reclocking? 384 needs firmware version 3.3 or later and displays as 192 on the LEDs

(I am somewhat ashamed to say :-) that) the FIFO is not in the system. How would I be able to switch between PCM and I2S?. That is why I asked Ian if he plans to update the firmware to allow DSD compatibility. The amount of data in DSD 64 is the equivalent of 2x44.1 and DSD 128, the equivalent of 88X2, so there should be sufficient FIFO memory...

still?

well no you cant, but there is more to the problem than memory size for working with DSD. DSD is essentially an analogue waveform represented in a 1bit stream, the FPGA in fifo is not set up for 1bit..is it?

needs a different module, not just different firmware. myself I dont see whats so special about DSD so far in my system

maybe if there was more variety of music available...
