Yes, a USB cable. I also have a sound card, but want to use the TEAC

I would take this step by step.

First you should use aplay to find out what works and what doesn't.  Find a .wav file of representative music somewhere or create one (use soundconverter for instance).

Run "aplay -l" to make sure that your TEAC card is card 1 (it looks as though it is but check)

Then try playing the resulting .wav file with aplay through the TEAC, like this:

aplay -D hw:1,0 mysong.wav

(this will play at full volume if it works so make sure you have your volume turned way down)

If that doesn't work, try

aplay -D plughw:1,0 mysong.wav

Assuming one or the other of those works...

Second, is the TEAC dedicated to MPD's use, or will you want other programs to use it (like VLC)?

Assuming it's dedicated, then I would configure MPD to talk directly to the TEAC through ALSA, especially if you have music at varying bit rates and you want to pass them through untouched.

I run two music servers in my house, both with MPD and dedicated DACs.  My audio output stanza in my /etc/mpd.conf looks like this:

audio_output {
enabled         "yes"
type            "alsa"
name            "Schiit Bifrost"
device          "hw:2,0"
mixer_type      "disabled"
auto_resample   "no"
auto_channels   "no"
auto_format     "no"
dop             "no"
}

You would have to change the name and the device.

If the aplay experiments didn't work or you don't want to dedicate, then get back to the list.
