Hallo Entwickler,

ich wollte mir heute mal seit längerem wieder ein Musikstück auf meinem Linux Desktop anhören, aber es kam nur knacken und Soundschnipsel raus.
Ich habe jetzt den Sound schon länger nicht mehr genutzt, aber soweit ich mich erinnere funktionierte er zumindest vor 2 Wochen noch (ich mache mindestens wöchentlich ein Upgrade aus dem Testing Repository).
Auch musste ich feststellen, dass Filme komisch ruckelig ablaufen. Das ist mir ebenfalls neu :-)
Eine kurze Internetrecherche hatte dann ergeben, dass es Probleme mit dem Intel HDA Treiber und shared Interrupts geben könnte . Ein "cat /proc/interrupts" ergab dann auch, dass sich der intel_hda und der sata_nv einen Interrupt teilen.

Code:
            CPU0      CPU1     
  0:        129          0  IO-APIC-edge      timer

Laut der Internetquelle soll man das ganze lösen können, indem man in die Datei "/etc/modprobe.d/alsa-base.conf" die Zeile "options snd-hda-intel enable_msi=1" einfügt.
Nachdem ich das probiert hatte ist mein System beim Booten mit einem Bildschirm voll "intel-hda: Spurious Interrupts" hängen geblieben. Neu starten konnte ich erst, seitdem ich im BIOS den Soundchip abgeschaltet habe.

Mit gelöschtem "alsa-basic" und wieder aktiviertem Sound-Chip gibt "lspci -vnn" folgendes aus (gekürtzt, wegen des 10k Zeichen-Limits für Beiträge):

Aber vielleicht hat mir trotzdem einer einen Tipp, wie ich den Sound wieder zum laufen bekommen könnte.

Filme laufem übrigens bei abgeschaltetem Sound-Chip wieder ganz normal, nur halt ohne Ton :-(
