Ich habe heute einen Intel NUC mit CentOS7 neu installiert und beobachtet, dass etwa 5 Sekunden nachdem die Audiowiedergabe stoppt – beispielsweise VLC – die Lautsprecher extrem laut zu brummen anfangen, so als w\u00fcrde man das Klinkenkabel nur halb einstecken.<\/p>\n
Meine Vermutung, CentOS schaltet die Soundkarte ab, war dann auch tats\u00e4chlich richtig, der Workaround ist hier:<\/p>\n
Um das permanent zu bekommen, packt man das in die Datei \/etc\/rc.local und vergisst nat\u00fcrlich nicht, die auch gleich noch mit chmod +x Ausf\u00fchrbar zu machen.<\/p>\n Die Methode, dem Intel-Soundkartentreiber in \/etc\/modprobe.d Parameter mitzugeben funktioniert bei mir \u00fcbrigens nicht, der Treiber ignoriert diese.<\/p>\n","protected":false},"excerpt":{"rendered":" Ich habe heute einen Intel NUC mit CentOS7 neu installiert und beobachtet, dass etwa 5 Sekunden nachdem die Audiowiedergabe stoppt – beispielsweise VLC – die Lautsprecher extrem laut zu brummen anfangen, so als w\u00fcrde man das Klinkenkabel nur halb einstecken.
