OK, hier ist die Geschichte. Ich habe seit etwa einem Jahr einen JDS Lab. C5D USB DAC und gestern wollte ich Ubuntu 14.04 ausprobieren. Also habe ich Ubuntu installiert, einige Updates durchgeführt und den DAC angeschlossen ( sudo alsa reloadund killall pulseaudioBefehle wurden verwendet).
Nach der Eingabe von "Toneinstellungen" Menü und Analogausgang für C5D ausgewählt, ich habe Testton ausprobiert. "Links vorne" Und "Rechts vorne" Ton erzeugt als "Hrrr, Hrrrr" Und "Hrrrr, Hrrrr". Ich habe sogar versucht, Musik und Videos abzuspielen – dasselbe Ergebnis.
Vielleicht ist es ein DAC-Problem? Also habe ich Windows und dann Kali Linux geladen, es hat in beiden perfekt funktioniert.
Nach der Rückkehr zu Ubuntu habe ich versucht herauszufinden, ob das System DAC richtig erkennt. Dies ist die Ausgabe für einen Befehl:

Also wird der DAC richtig erkannt.
Irgendwelche Vorschläge, Freunde? Und entschuldigt mein schlechtes Englisch ;)

Ich habe keine Probleme mit meinem C5D unter Ubuntu 14.04. Mein PulseAudio daemon.confhat die folgenden Änderungen, die Sie ausprobieren können, um zu sehen, ob diese Ihr Problem lösen:
default-sample-format = s24le
default-sample-rate = 48000
