alsa will nicht mitspielen ...

[Nemesis]

hi,
ich habe seit gestern das problem, dass ich in totem eine fehlermeldung bekomme, wenn ich etwas in ihm abspielen möchte:

The audio device is busy. Is another application using it?

bisher gings immer, ich hab auch nichts am system gebastelt, das einzige ist, dass ich skype installiert habe.
nutzen tu ich normal alsa, ich habe auch alles auf alsa/aplay gestellt, xmms tut, gaim spielt sound.
wenn ich totem aus der konsole als root starte, habe ich gerade festgestellt, dann funktionierts, mache ich selbiges als normaler user, dann spuckt er folgendes aus:

audio_alsa_out: snd_pcm_open() of iec958:AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2 failed: Invalid argument

an was könnte dies liegen?


thx

edit:
jetzt gehts als root auch nichtmehr, ich habe in "Bearbeiten -> Einstellungen -> Audio" von dem voreingestellten stereo auf AC3 Pass-Through getellt,r jetzt gehts nichmehr, wenn ich wieder auf stereo zurück stelle, kommt trotzdem derselbe fehler

er gibt dann auch wieder die selben fehler aus:

load_plugins: plugin a/52 will be used for audio streamtype 00.
