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.

Hi Kim,
the format has been already commented, no result.
My impression is that there should be some issue in ALSA mixer, as I found on
Google that the warning messages
cannot get ctl value: req = 0x83, wValue = 0x201, wIndex = 0xa004
are related to it. But I don't know how to check this....
Thanks again
Ciao
Bruno

I tried to play it via S/PDIF, and it sounds correctly. I have music files both standard and high sample rates (e.g.
44,1 - 96 and 192 kHz) but none of them play via USB output but only via S/PDIF output. I now will try to leave the
O.S. on the USB stick (the CD live version) and configure it to see if in this way it sounds via USB also after
reboot. I will let you know.
I have no idea why. But since you can play via S/PDIF from the DAC, this means mpd is able to send USB signal to the
DAC.
At last, check the following /etc/mpd.conf to remove "format" line so that it
detects the bit-rate correctly:
audio_output {
type "alsa"
name "My ALSA Device"
device "hw:0,0" # optional
# format "44100:16:2" # optional
# mixer_device "default" # optional
# mixer_control "PCM" # optional
# mixer_index "0" # optional
}
