[PROBLEM] Latency reduction when using audio/video player as input

[Tim Curtis]

There is no built in audio capture feature in moOde so I can't speak to that flow but wrt to the default MPD audio flow with no DSP or Loopback it looks like below.

MPD -> ALSA COPY -> plughw or hw -> device

This flow is implemented in the file below.

Code:

/etc/alsa/conf.d/_audioout.conf

If you want to bypass the ALSA COPY part for testing then manually edit /etc/mpd.conf and set device to ""plughw:N,0" or "hw:N,0" where N is the card number of your output device then restart MPD via systemd. 

Code:

# mpd.conf
.
.
audio_output {
type "alsa"
name "ALSA Default"
device "_audioout"
mixer_type "hardware"
mixer_control "Digital"
mixer_device "hw:0"
mixer_index "0"
dop "no"
stop_dsd_silence "no"
thesycon_dsd_workaround "no"
}

# Restart
sudo systemctl restart mpd

Note: Don't make any changes to MPD ir ALSA settings in the WebUI because they will overwrite manual changes to mpd.conf.
