[Voyage-linux] mpd.conf and DSD files

[Demian Martin]

I have not played with it much since I got it working. Jurgen Kramer is the
guy who put it together. I have not heard many complaints but that may be
due to the real lack of content for the format. He can be found on the mpd
dev mail list:  musicpd-dev-team-request at lists.sourceforge.net  . The few
times I tried it I did not see that behavior.  What platform/motherboard and
what DAC are you using?
