N100DC-ITX kein Sound

Angeblich wurden keine Ein- und Ausgabegeräte gefunden. Nebenbei auch IOMMU nicht. Bei diesen SoC Plattformen gibt es immer wieder Probleme.

So sieht der Abschnitt im Infozentrum aus:

            rt.prio       = 88

		module.version = "1.4.7"
		nice.level = "-11"
		rt.prio = "88"

Module #2
	Name: libpipewire-module-protocol-native
	Argument: {
            # List of server Unix sockets, and optionally permissions
            #sockets = [ { name = "pipewire-0" }, { name = "pipewire-0-manager" } ]
        }
	Usage counter: n/a
	Properties:

		object.serial = "2"

		module.version = "1.4.7"

Was lässt sich da tun ?

Früher ließ sich das Problem lösen, indem unter xorg.conf.d in einer Datei

BusID “PCI:0:2:0”

eintrug. Leider startet dann der X-server nicht mehr.

Vielen Dank. Ich habe den Fehler gefunden. Es ist die Hardwareerkennung. Die Buchsen erkennen, ob Lautsprecher eingesteckt sind. Es waren keine eingesteckt.
→ die Lösung waren die alsa-utils, auf die ich erst durch den Post gekommen war. Die zeigen vorhandene Realtek ALC897 an. Dort werden auch die Kanäle gezeigt, die von KDE nicht angezeigt werden.
