Hi,

I've got some follow up questions to make sure we're om the same page
and I don't make unwanted adjustments/additions to mpd.

To recap, current svn contains the dsdiff_decoder_plugin/dsd2pcm combo
to: 
1. Read .dff (DSDIFF) encoded DSD files and extra the channel data
2. Convert the DSD data to 352.8kHz stereo PCM in SAMPLE_FORMAT_S24_P32
format
3. MPD converts this down to whatever rate is set/selected audio ouput
is capable of.

My new decoder will
A. Re-uses all of 1)
B. Convert the DSD data to dCS spec DSD-over-USB data in 'PCM'
SAMPLE_FORMAT_S32 (or SAMPLE_FORMAT_S24_P32 if needed)
C. MPD just plays a 176400 PCM stereo stream through ALSA

With this I'd like to:
- expand the dsdiff_decoder_plugin to output to DSD-over-USB PCM data in
SAMPLE_FORMAT_S32 if the user selects it in the configuration
- Add dsd2usb function to dsd2pcm or create a separate dsd2usb module

I you can agree on this approach I can start working on it.

Thanks for your time!

Jurgen
