simras Posted February 6, 2016 Share Posted February 6, 2016 Hello, since I changed mother board, I noticed that my sound stopped functioning with “Loudspeaker interns” if for example I launched a video youtube, launched a music, it is completely random. I don't have activate the sleep, it just random when i use it. For the SMBIOS I selected a iMac 14,2 and in “Devices” I have “AFGLowPowerState”. When I also lose the sound in the control panel I always see the connected apparatuses and I know that to make the sound back, I switch on my headphones wireless connected in usb which has its own card sound which work but not my speaker, i need to wait 3 minutes and after the sound come back.
