Alc887 audio works fine in 10.12, but after a few seconds if there is no audio playback, it is as if it were disconnected, it is heard in the speakers as before starting the operating system. After playing any sound returns to normal, To reproduce .... a few seconds later the same cycle ...help me please ...
Thanks for your time. I remember that changing the definition to MacPro 5.1 does not happen, it works fine. But I will continue trying with iMac14.2 which is the one I believe closest to my configuration.
I have a strange issue with audio on Sierra 10.12.4 . While it works just fine, it seem to strangely stop working every other reboot. So when I turn off my pc after a 'good' session, next one it stops working (in Sys Pref - Sound it shows 4 rows of 'Digital Out HDMI', as outputs, and none works) and I have to reboot once more to make it work again.
Does anyone encountered this thing?
I have Realtek 887 and I installed the correct Voodoo for my device.
