Hello,
When I updated from 10.10 to 10.11 the sound of both mac os and windows disappeared. On both OS the sound devices are there and when I play something on youtube, the system shows that there is output sound, but nothing plays. I already tested the speakers and they are working. When I boot windows directly, without using the bootloader, it is still without sound. I even reverted to my past installation of the 10.10 and it's also without sound, but showing the devices, like the 10.11 and windows.
1. No sound since upgraded from 10.10 to 10.11. Windows 7 that had sound also doesn’t have sound anymore.
I see the devices (preference panes / sound / output) and they seem to work, but no sound comes out of the speakers. Devices showing :1 Internal speakers, 2 Line Outs, 1 Digital Out (this doesn’t work).
2. 10.11.2 / Gigabyte ga z77 ds3h / bios F9 / 3.4ghz intel core i5 / EVGA GeForce GTX 560 SE 1536MB
3. Unibeast / Multibeast 8.0.1 : selected ALC887/888b (see attachment)
11. Speaker: Genius SP-HF500A connected in the back green port of the motherboard
Thanks for the help!
