In einer früheren OSX-Version alt-cmd-P-R
ertönt die wieder aktivierte Kombination nach einem Neustart, jedoch nicht in Yosemite.
In einigen OSX-Versionen sudo killall coreaudio
funktioniert der Befehl auf einem MacBook Air von Mitte 2013, jedoch nicht in Yosemite 10.10.3. Dieses Problem trat auch in Yosemite 10.10.1 beim Upgrade auf die neue Version auf. Ich habe es geschafft, durch die obigen Prozeduren Geräusche zurückzubekommen.
Ich sehe keine Audioquellen in den Soundeinstellungen, nachdem dieses Problem aufgetreten ist, auch nach diesen beiden Versuchen, dieses Problem zu lösen.
Wie können Sie Sounds in OSX Yosemite 10.10.3 zurücksetzen?
Ich kann kostenlosen AppleCare-Support erhalten, wenn dies die einzige Lösung ist, da ich eine 5-Jahres-Versicherung habe. Ich möchte es jedoch nicht tun, wenn es keine andere Lösung gibt.
Veranstaltungen 23.5.2015
Apple brachte neue Updates in den App Store, mit denen das Problem vorübergehend behoben wurde (3 Stunden):
Ich habe mein Macbook Air 3 Stunden lang benutzt, habe angehalten und das Macbook wieder geöffnet - das gleiche Problem ist wieder aufgetreten. Ich verstehe den Grund des OSX-Fehlers nicht wirklich.
Der Befehl cd /System/Library/Extensions/AudioAUUC.kext ; ls -alt
gibt

die sind eher neu.
Der Befehl kextstat -b com.apple.driver.AudioAUUC
gibt
Index Refs Address Size Wired Name (Version) <Linked Against>
was bedeutet, dass das Audio-Ding nicht wie mit @danielAzuelos besprochen geladen wird.
Daniels Befehl /usr/bin/sudo kextutil -t -v 6 -b com.apple.driver.AudioAUUC
