[Musicpd-dev-team] DSD over USB
Hi , I've been testing the latest git with DSD over USB support this morning. I'm using an XMOS UAC2 board with modified firmware supporting v1.0 of the dCS suggested standard. https://www.xcore.com/projects/dsd-audio-over-usb OS is ARM linux. So far I haven't gotten it to work. I noticed that you make mention of: http://www.dcsltd.co.uk/page/assets/DSDoverUSB.pdf Have you applied the marker bytes as described in the PDF or the updated marker bytes refered to in the latest v1.0 spec below? http://www.audiostream.com/content/usb-link-dsd-audio-pcm-frames-andres-koch Thanks -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Musicpd-dev-team mailing list Musicpd-dev-team@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/musicpd-dev-team
Re: [Musicpd-dev-team] DSD over USB
You can enable it by adding to the ALSA section in mpd.conf: dsd_usb yes Obviously, it is important to have bit-perfect 24 bit playback on the wire. A conversion will be destructive in any case. dmix must be disabled. It's experimental so we don't now if it works or needs works. Please provide any feedback!

I took a quick look at the code, it seems it supports the pre-1.0 version of the standard (0xAA markers). I'll give it a test tomorow. My DAC supports both version 1.0 and pre-1.0.
