Hopefully using the firewire snd driver will be fixable.

Thanks for that tip! I have it working now with plughw as well...

I took a quick look at the code, it seems it supports the pre-1.0

OK I just test the new code, unfortunately it does not work for me
either. It fails to setup ALSA. I tried both through the firewire driver
and through a SOtM usb-to-spdif converter.
Mytek DAC through firewire snd driver:
Mar 23 12:28 : output: Failed to open DAC [alsa]: Failed to configure
DSD-over-USB on ALSA device hw:1,0
Through SOtM usb-to-spdif converter:
Mar 23 12:32 : output: Failed to open sotm [alsa]: Failed to configure
DSD-over-USB on ALSA device iec958:CARD=S20,DEV=0
@Max can you shed some light on this? Are there any configuration
options I need to try/add?
My mpd.conf enty for the SOtM is:
# Entry for SOtM dX-USB HD - USB to SPDIF/Toslink/AES-EBU
audio_output {
typealsa
namesotm
device iec958:CARD=S20,DEV=0
use_mmapno
mixer_type disabled
dsd_usb yes
}
I have also tried with use_mmap yes.
With my old code is opens the ALSA device with:
Mar 23 12:38 : output: opened plugin=alsa name=sotm
audio_format=176400:32:2
Mar 23 12:40 : output: opened plugin=alsa name=DAC
audio_format=176400:32:2
These work for my installation.
BTW would it be doable to enable dsd_usb for pipe output? That is really
handy for debugging output of the decoder.

This means support for v1 will be a fairly easy addition. We only need a way to select between v1 en pre-v1.
