    Hallo,
    gibt es eine Möglichkeit, diesen pcm2704 usb dac irgendwie zu integrieren? Bei piCore oder dem bisherigen squeezeplug-image funktionierte alles bestens.

    Weiß jemand Rat?

    Hallo rel,
    Du kannst versuchen bei “Raspberry Einstellungen” die Option “USB-DAC” zu wählen bei Soundkarte auswählen. Diese Option aktiviert den allgemeinen Treiber von Raspberry Pi für USB-DAC’s.

    Danke, Heiner. Hab ich natürlich probiert, klappt nicht.
    Kann man die Treiber irgendwie nachinstallieren?

    6. November 2015 at 16:13 #16794

    Das könnte eine Möglichkeit sein. Um dies herauszufinden, tun Sie bitte folgendes: Wählen Sie sich bei Ihrem Gerät über die Konsole ein (Bildschirm und Tastatur oder Putty, user: root pw: max2play), stecken Sie den DAC ein, geben Sie “dmesg” ein und klicken Enter. Der ausgegebene Text wird uns weiterhelfen Ihr Problem zu lösen.

    Hallo rel,

    es sieht so aus, als würde immer noch ein IQaudIO-Dac als Soundkarte voreingestellt sein. Folglich kann auch dein USB-DAC nicht betrieben werden. Welche Einstellung kannst du unter Raspberry Pi Einstellungen sehen?
    Welchen Raspberry Pi nutzt du? Es sieht so aus, als wäre es kein Raspberry Pi 2? Volle Unterstützung können wir nur dafür gewährleisten. Ich empfehle, über einen Umstieg nachzudenken und das USB-DAC damit zu betreiben. Stelle deine Frage noch zusätzlich in einem Raspberry Pi-Forum und erkundige dich nach der Kompatbilität des DACs mit deinem Raspi.

    Hallo Maximilian,
    die Sache lässt mir keine Ruhe. Ich habe den Pi samt des USB DAC pcm2704 vorher ohne Probleme mit squeezeplug genutzt, da konnte man den DAC auswählen. Das Gleiche sollte jetzt natürlich auch mit Max2Play klappen.
    Ziel ist es, an einem Pi2 3-4 solcher USB-Dac anzuschließen und darauf über Multisqueeze mehrere Player zu simulieren.

    Habe jetzt alles auf einem Pi2 installiert, den USB DAC pcm2704 angesteckt und bekomme folgende Ausgabe bei dmesg:

    Ich hoffe, es gibt hier eine Lösung…vor allem, weil es bei Squeezeplug ohne Probleme mit diesem DAC funktionierte. Danke.

    REL

    28. November 2015 at 15:14 #17057

    So, habe eine Lösung gefunden:
    Max2play auf dem Pi2 installiert, dann unter dem Reiter “Raspberry Einstellungen” unter “Wähle Soundkarte, die beim Start geladen werden soll” als Soundcard folgendes eingestellt: USB Soundcards (Northstar Essensio, Hiface and others)
    Dann Multisqueeze als Plugin installiert, dort unter “Status instance” und “Erweiterte Optionen” die Soundkarte “default – USB Audio DAC, USB audio” eingestellt, bei der zweiten Instance das Gleiche mit Card=DAC_1 am Ende.
    Reboot. Fertig.

    Jetzt laufen auf dem Pi2 gleichzeitig 2 separate Player über zwei recht günstige USB DAC pcm2704 in ansprechender Qualität.

    REL

    PS: Einen 3. USB-Port habe ich ja auf dem Pi noch frei (2xDAC, 1xUSB-Stick mit MP3), ich werde also noch einen USB DAC anschließen und eine 3. Instanz ausprobieren.

    31. May 2016 at 12:46 #20415

    Hallo,

    Ich sehe, Sie haben Erfahrung mit pcm2704.

    Haben Sie haben es geschafft, das Ganze zu laufen?

    Die Klangqualität ist gut?

    Ist es möglich, mit dem Equalizer zu handeln?

    Wie haben Sie Instanzen installiert?

    Vielen Dank für Ihre Austausch
