[Voyage-linux] USB DAC problems with Voyage 0.8 and new Voyage 0.8.5

[Kim-man 'Punky' TSE]

Hi Bruno,

I read your mails again and questions:

1. What ALIX board do you have?
2. You repeatedly say you can play through S/PDIF.  Do you mean S/PDIF on ALIX board or on your Calyx DAC?
3. show me the output again for the following commands:
     a) cat /proc/asound/cards
     b) mpc outputs
4. attach your /etc/mpd.conf in reply mail.
