Snips / MPD gleichzeitige Soundausgabe

[Che007]

Hallo zusammen,

bezugnehmend auf meine Nachricht hier: https://forum.fhem.de/index.php/topic,89548.msg948407.html#msg948407 habe ich leider noch das Problem, dass Snips und MPD auf einem Satelitten nicht gleichzeitig funktionieren.

Setup:
2x Raspberry Pi
1. FHEM
2. Snips mit MPD Server für Radio

Ausgangspunkt war sobald ich per Sprachkommando das Radio gestartet habe, gab Snips seine Antwort aus, jedoch wurde das Radio gestoppt und konnte so nicht aktiviert werden.

Anbei die configs:

# file:// protocol) or streaming files over an accepted protocol.

music_directory         "/var/lib/mpd/music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.

playlist_directory              "/var/lib/mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to

# files over an accepted protocol.
#
db_file                 "/var/lib/mpd/tag_cache"
#
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog, otherwise logging is disabled.

log_file                        "/var/log/mpd/mpd.log"

# This setting sets the location of the file which stores the process ID

#
pid_file                        "/run/mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before

# This setting specifies the group that MPD will run as. If not specified

Hi,

ich häng mich mal mit ran, ich hab ein ähnliches Problem bzw hatte da ich es aktuell quick n dirty gelöst habe, evtl gibts da ne besseren Ansatz.

Kurzüberblick:

- MPD und Snips gehen zeitgleich, Snips ist aber leiser als MPD, entweder ist das Radio viel zu laut oder Snips nicht zu verstehen
- Snips reicht seine erkannten Kommandos an Talk2fhem, dort wird dann alles (Snips und Telegram) ausgewertet und verarbeitet
- Ablauf:

z.B. Radio läuft

Kommando Hey Snips, über DOIF wird dann das Radio gestoppt und die Lautstärke am Snips PI erhöht um Snips zu verstehen, nach 15 sekunden Lautstärke wieder runter, nach 20 sekunden Radio wieder an - klappt ganz gut unschön ist nur folgendes:

Anschalten des Radio über Snips:

- Hey Snips....Radio an
- Radio beginnt kurz, Snips will aber das Commando bestätigen
- Radio stoppt
- Snips bestätigt
- 20 sekunden später Radio läuft wieder an

Eine Hardware (wie z.B. Soundcarte) kann nur von einem Programm exklusiv genutzt werden. Ihr müste also von der direkten Ansteuerung weg und über einen Sounddeamon gehen (wie z.B. PulseAudio).

Da ich Snips nicht kenne, kann ich dort keine Hilfe geben. MPD läuft bei mir über PulseAudio

[Che007]

Mit dem Software ALSA Mixer komme ich nicht wirklich weiter.
Hast du freundlicherweise die configs für Pulseaudio und mpd?

[Wernieman]

Ich lasse pulseaudio über den mpd user laufen .. wie ich das eingerichtet habe, ist eine guuuuute Frage ...

in mpd selber:

Code Auswählen Erweitern

audio_output {
        type            "pulse"
        name            "My Pulse Output"
#       server          "localhost"             # optional
#       sink            "remote_server_sink"    # optional
        mixer_type      "software"
}


Bei mir brauchte ich den Schalter mixer_type wegen der Hardware, besser wäre es, wenn es ohne geht.

[Che007]

Vermutlich liegt mein Problem auch daran, dass ich damals für den Snips den folgenden Eintrag in der Datei sudo nano /etc/systemd/system/multi-user.target.wants/snips-audio-server.service
machen musste um den u.a. Fehler zu beheben.
Eintrag:
[Service]
Environment="PA_ALSA_PLUGHW=1"

Ansonsten hatte ich bei der Audio Ausgabe von Snips diese Fehler:

Portaudio ist auch ein Sounddeamon .. ich weiß aber nicht, wie mpd dazu überredet wird, mit portaudio zu laufen ...

Scheint wohl nur mit externen Lautsprechern zu funktionieren und nicht  mehr der analogen Klinke.

ALSA kann verschiedene Quellen gleichzeitig abspielen. Dazu gibt es dmix, was die Signale zusammenführt und auf der definierten Soundkarte ausgibt. Man darf die Karte nur nicht direkt aus den Programmen ansprechen. Dann blockiert sich alles gegenseitig.
Die Configs habe ich bei mir erfolgreich im Einsatz. https://forum.fhem.de/index.php/topic,89548.msg945876.html#msg945876
Snips scheint generell "playback" als Ausgang und "capture" als Eingang zu verwenden.
Beim Raspi von Che007 sind nur die Bezeichnungen anders. Für "ALSA" kann man in der asound.conf auch "hw:0,0" schreiben.
Man möge mich berichtigen, sollte ich mich irren.

Am Ende des Monats kommt mein USB China Lautsprecher dann werde ich es noch einmal probieren. Denke auch, dass es gehen muss, aber entweder hängt sich der MPD Server auf oder der exlusive Soundkartenzugriff blockiert.

Ich werden es für die Übergangszeit wie CBSnake machen. Alles zurück zum Urspungszustand. Die Snips Ansage stoppt das Radio. Ich werde über FHEM eine Pause einbauen und das Radio einfach verzögert, quasi nach der Snips Ansage, einschalten.

Sorry, ich habe mich doch geirrt. Habe die Konstellation nachgestellt und festgestellt, dass der Analogausgang vom RPi dmix scheinbar nicht unterstützt.

Nun habe ich ein Seeed-6Mic-Array und es erst nicht parallel mit mpd zum laufen bekommen. Nach Herstellerinfo:

Limit for developer using 6-Mic Circular Array Kit(or 4-Mics Linear Array Kit) doing capture & playback the same time:
-1. capture must be start first, or else the capture channels will possibly be disorder.
-2. playback output channels must fill with 8 same channels data or 4 same stereo channels data, or else the speaker or headphone will output nothing possibly.
-3. If you want to play and record at the same time, the aplay music file must be mono, or you can not use this command to play.

habe ich die Channels und die Bindings gelöscht, sowie eine Samplingrate von 44100 eingetragen.

# The IPC key of dmix or dsnoop plugin must be unique
# If 555555 or 666666 is used by other processes, use another one


# use samplerate to resample as speexdsp resample is bad

Hi Jens,

konnte jetzt auch mit USB Lautsprechern nachstellen, dass deine asound.conf funktioniert.
Danke dafür.

Kleiner Typo bei dir:

ctl.smips - < das m
