Нужна помощь с MPD

. Я запускаю MPD (v0.21.20) на компьютере с Ubuntu и использую клиент ncmpcpp на той же машине. У машины рабочий звук, поскольку я использую его для других приложений с графическим интерфейсом.

Вот отрывок из mpd.conf, который мне кажется проблематичным:

    audio_output {
    type        "alsa"
    name        "My ALSA Device"
#   device      "hw:0,0"    # optional
#   device "iec958:CARD=Intel,DEV=0"
    mixer_type      "software"      # optional
#   mixer_device    "default"   # optional
#   mixer_control   "PCM"       # optional
#   mixer_index "0"     # optional
}
#

#audio_output {
#   type        "pulse"
#   name        "My Pulse Output"
#   server      "127.0.0.1"     # optional
#   mixer_type      "software"
#   device "iec958:CARD=1,DEV=1"
#   mixer_control   "PCM"
#   sink        "remote_server_sink"    # optional
#} 

Когда я выбираю ALSA, файл WAV начинает воспроизводиться в ncmpcpp, но не производит звука.

Nov 10 17:51 : avahi: Service 'Music Player @ mServer' successfully established.
Nov 10 17:51 : client: [0] opened from 127.0.0.1:44676
Nov 10 17:52 : player: played "1.wav"

Но когда я выбираю ПУЛЬС, ncmpcpp просто остается приостановленным все время:

Nov 10 17:50 : client: [0] opened from 127.0.0.1:44670
Nov 10 17:50 : avahi: Service 'Music Player @ mServer' successfully established.
Nov 10 17:50 : exception: Failed to open "My Pulse Output" (pulse)

Nov 10 17:50 : exception: Failed to open "My Pulse Output" (pulse)
Nov 10 17:50 : exception: nested: failed to connect: Connection refused

Вот результат команды aplay -l, показывающий все аппаратные устройства воспроизведения:

А вот результат mpd --stderr - -no-daemon --verbose команда, которая, похоже, не показывает никаких ошибок, которые могли бы объяснить отсутствие звука:

На этом этапе я действительно не знаю, где искать дальнейшие способы устранения неполадок, чтобы звук работал с MPD, поэтому любой указатели будут полезны!
