DoP is "DSD over PCM", see for example
https://en.wikipedia.org/wiki/Direct_Stream_Digital

In your case, your TEAC may support this, so if you have DSD format music
you might want to give it a try.  I am not sure if DoP support is in all
recent versions of MPD so you might want to investigate that as well to
make sure that your version supports it.

Sure. It's actually the same as yours, modified for this environment:

audio_output {
enabled "yes"
type"alsa"
name"TEAC USB"
device  "hw:3,0"
mixer_type  "disabled"
auto_resample   "no"
auto_channels   "no"
auto_format "no"
dop "no"
}

By the way, what does the 'dop' parameter do? I couldn't find any
references in the man page.

USB always uses digital data.

The output is called "Analog" because that's what is at the other end.
It would be called "Digital" if it were an S/PDIF output.

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.

Bob, what connects your computer to your TEAC?  A USB cable?

What music player do you use?

What is the output of "aplay -L" in a terminal window?

Sorry, forgot to say that alsamixer just shows a single playback
