what are you talking buddy? we can't select a sound device from Sound Preferences.no sound output devices. yosemite not recognize sound card and speakers. i think this is a driver issue.am i wrong?Same answer as in another thread:
ALC892 worked for me after selecting the right sound device in System Preferences. Took me about to find this simple solution
Hope it works for you, too
Yes. Audio is not configured correctly on your system.i think this is a driver issue.am i wrong?
Bad advice. This solution ensures audio failure after each Software Update.Try the old version of multibeast and only select your audio drivers.
