OS X 10.9.2 Cannot work after long sleep
Closed this issue · 1 comments
Headphone(sometimes internal speaker) doesn't work after long sleep. No sound and no auto detection. Just turn off screen(go to Apple menu and select Sleep… wait for 5 seconds and press any key on the keyboard), log in again, all thing goes to work. These can be fixed? Thanks for your efforts.
Unfortunately, no...I have no way to resend the verb because by all symptoms EAPD is enabled, while in fact it's not. This is one of the reasons I had to make it constantly monitor the power state of the codec (second is the loss of jack sense after second PIO) so that Apple-Sleep could be used as a workaround.
EAPD reports it's state as enabled based on IRR response, yet it's not, because codec sits in a Low Power state after long sessions of sleep and doesn't allow for sound to pass. This is part AppleHDA 2.6.0 part codec fault. Some codecs do this when you reboot from Windows to OSX - the internal node associations get stuck and you need to completely power cycle the codec to make it work properly (for my ALC269VB headphones will be detected, but audio won't pass through).
