Liebe Leserinnen und Leser, ich benötige Hilfe, um einem Acer Switch 10 (Intel Atom Z3735F Baytrail) Töne entlocken zu können. Ausgabe von uname -a:

Der Benutzer tobias ist in der Gruppe audio

tobias@antigone:~$ groups tobias
tobias : tobias adm cdrom sudo audio dip plugdev lpadmin sambashare

aber aplay gibt eine Fehlermeldung aus:

tobias@antigone:~$ aplay /usr/share/sounds/alsa/Front_Center.wav
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Verbindung beendet

aplay: main:788: Fehler beim Öffnen des Gerätes: Verbindungsaufbau abgelehnt

Pulseaudio ist installiert, aber startet nicht:

tobias@antigone:~$ ps -C pulseaudio

tobias@antigone:~$ dpkg -s pulseaudio

Was kann ich tun, um auf dem Rechner Klänge abspielen zu können? Vielen Dank für hilfreiche Hinweise im Voraus!

Schmeiß das einfach mal bei Google rein, kommt genug ...

Mal im Terminal

alsamixer

aufrufen und die Soundkarte (bytcrrt5640) (F6) auswählen und sehen wo die Regler stehen.

Ausgabe von

pactl info 

cat /var/log/syslog | grep 'intel\|bytcrrt5640\|pulse\|alsa\|byt'

zeigt was?

Vielen Dank für die Rückmeldungen zu meinem Acer Switch ohne Töne! Mit alsamixer erhalte ich diese Ausgabe für "Speaker":

Entsprechend der Meldung des fehlgeschlagenen pulseaudio-Starts ist das entsprechende Symbol des Klangreglers im Panel ausgegraut.

Dein Kopfhörer im alsamixer mal einschalten,steht ja auf Mute (MM) mit der M Taste unschalten. Dann auch die Regler mal hochziehen (Pfeiltasten) Im Terminal dann eingeben

speaker-test

Ausgabe ist?Ton zu hören?

Vielen Dank an Kellerkind und Hakel! Die Wiedergabe von Klängen funktioniert jetzt. Das Rumexperimentieren mit alsamixer hat mich darauf gebracht, mit den Begriffen "bytcr-rt5640" und "hdmilpeaudio" im Internet zu suchen, und ich bin darüber auf https://github.com/plbossart/UCM/issues/18 gestoßen. Danach handelt es sich um eine bekannte "PulseAudio issue with HDMI", die sich bei mir so wie unter https://github.com/plbossart/UCM/issues/13 von F5LVG am 18. Februar 2018 beschrieben mit den entsprechenden Dateien von https://github.com/plbossart/UCM/tree/master/byt-rt5640 lösen ließ.

👍 Prima. Hast du HdmiLpeAudio in die Blacklist eingetragen oder musstest du es nicht?

Ich habe in /etc/modprobe.d eine Datei namens blacklist_snd_hdmi_lpe_audio.conf mit der Zeile blacklist snd_hdmi_lpe_audio angelegt und die Dateien "HiFi" und "bytrt-5640.conf" von https://github.com/plbossart/UCM/tree/master/byt-rt5640 in den von mir angelegten Ordner /usr/share/alsa/ucm/byt-rt5640 kopiert.

Alles klar 😉 Manchmal ist es erstaunlich,da die Änderung in der HiFi.conf schon 4Jahre alt ist und selbst in der 19.10er Version immer noch nicht geändert/übernommen wurde 😕

In der Version 19.10 sieht die HiFi.conf so aus

Hi Tobias!

ich habe hier einen Acer Aspire Switch 10 E auf dem Ubuntu 19.10 läuft und ich habe ebenfalls keinen Sound. Karte scheinen wir dieselbe verbaut zu haben, doch leider höre ich noch immer nichts, nachdem ich dies gemacht hab, was du im Zitat beschreibst.

cat /proc/asound/cards 
 0 [bytcrrt5640    ]: bytcr-rt5640 - bytcr-rt5640
                      bytcr-rt5640-stereo-spk-in3-mic

Weiß jemand weiter?

TobiasH: welches Gerät wird dir unter den Klangeinstellungen angezeigt? Bei mir heißen sie nur "Speakers".

ich zeige euch mal einen Ausschnitt der Ausgabe von "sudo pulseaudio -vvv", der mir merkwürdig erscheint, weil hier von einem Dummy-Audiodevice die Rede ist. ist das normal?

I: [pulseaudio] sink.c: Created sink 0 "auto_null" with sample spec s16le 2ch 44100Hz and channel map front-left,front-right
I: [pulseaudio] sink.c:     device.description = "Dummy-Ausgabe"
I: [pulseaudio] sink.c:     device.class = "abstract"
I: [pulseaudio] sink.c:     device.icon_name = "audio-card"
I: [pulseaudio] source.c: Created source 0 "auto_null.monitor" with sample spec s16le 2ch 44100Hz and channel map front-left,front-right

Hier noch der Output von "aplay -l":

~$ aplay -l
**** Liste der Hardware-Geräte (PLAYBACK) ****

  Sub-Geräte: 1/1
  Sub-Gerät #0: subdevice #0

Ich habe nachgesehen, im Gerät ist laut Hersteller eine Realtek Karte verbaut. Sollte die nicht auch als solche erkannt werden?

EDIT: Ich häne mal den Output von alsa-info als .txt hier an, vielleicht kann jemand von euch etwas damit anfangen.

Hallo Leute!

Entschuldigt bitte das Doppelposting, aber ich bin wirklich ratlos. Über Google komme ich mit den Suchbegriffen "Intel HDMI/DP LPE Audio" und "bytcr-rt5640" immer auf dieselbe Lösung, die auch für den Kollegen TobiasH funktioniert hat. Und da ich ja auch dasselbe Gerät habe wie der Kollege, frage ich mich, was ich übersehe. Hier scheint das Blacklisten des HDMI/LPE devices im Kernel zum Erfolg geführt zu haben. Die anderen Konfigurationsdateien wurden offenbar direkt von github runtergezogen über die paar Kommandos oben. Es hat also dieselbe Lösung geholfen.

EDIT: Dieser Thread hat "Magic Scripts" verlinkt, die ich mir nicht mehr herunterladen kann, sie wurden anscheinend gelöscht. Es wird dort such gesagt, dass man sie minimal tweaken muss, aber nicht genau wie. Ohne diese Scripte will ich mit dieser Anleitung nicht mit Punkt 3. "pulseaudio" weiter machen, denn es fehlt ja ein entscheidender Schritt. Oder sollte ich? Ich weiß eigentlich nicht, was ich da tun würde. Was meint ihr?

LG und danke, A

cat /usr/share/alsa/ucm2/bytcr-rt5640/HiFi.conf: Datei oder Verzeichnis nicht gefunden

GLG, A

Hattest du nicht geschrieben das du dich an diesen Thread gehalten hast?? Es ist nichts davon zu sehen. Nur in meinen Augen recht

merkwürdige Ordner – z.b. /usr/share/alsa/ucm/bytcr-rt5640-mono-spk-dmic1-mic

Wie soll es also weitergehen?

Hallo Kellerkind!

Ja, ich hab mich an diesen Thread gehalten. Das heißt konkret, dass ich genau das gemacht habe, was der Kollege getan hat und was ich in meinem Eröffnungsposting auch zitiert habe, nämlich

in /etc/modprobe.d eine Datei namens blacklist_snd_hdmi_lpe_audio.conf mit der Zeile blacklist snd_hdmi_lpe_audio angelegt und die Dateien "HiFi" und "bytrt-5640.conf" von https://github.com/plbossart/UCM/tree/master/byt-rt5640 in den von mir angelegten Ordner /usr/share/alsa/ucm/byt-rt5640 kopiert.

Dieser Ordner existiert auch nach wie vor, die Files ebenso. Mehr war auch im Sinne des sich an diesen Thread Haltens nicht zu tun, oder hab ich da was nicht mitbekommen?

GLG, A

Edit: Dieser merkwürdige Ordner den du als Beispiel anführst betrifft glaube ich das eingebaute Mikrofon.
