SIMONE280303 Posted December 3, 2020 Share Posted December 3, 2020 hi guys, a few days ago I decided to install os high sierra on my computer to have my graphics card working too (I'm a beginner). all good but the sound of the speakers does not work. (speakers are connected to tv, so hdmi audio doesn't work) my motherboard supports ALC887. i tried to change id but nothing. what could I do? thank you so much my pc: gigabyte b250m-ds3h intel i5 7400 ram hyperx 8gb msi gtx 1050ti 4gb Quote Link to comment Share on other sites More sharing options...
NBABASKETBALL Posted December 3, 2020 Share Posted December 3, 2020 If you are sure that this your audio codec try all these layouts: 1, 2, 3, 5, 7, 11, 13, 17, 18, 20, 33, 40, 50, 52, 53, 87, 99 till sound works. For example alcid=20. Are you using clover or Opencore? Quote Link to comment Share on other sites More sharing options...
SIMONE280303 Posted December 3, 2020 Author Share Posted December 3, 2020 I've tried all these layouts already. I'm on clover. yesterday i tried to patch apple hda with layout id 5. you could see the audio image (not obscured as always) but the audio from hdmi doesn't work Quote Link to comment Share on other sites More sharing options...
NBABASKETBALL Posted December 3, 2020 Share Posted December 3, 2020 the problem could be that applealc does not support HDMI audio from your gpu. but I am not sure. Does onboard audio work? Quote Link to comment Share on other sites More sharing options...
SIMONE280303 Posted December 3, 2020 Author Share Posted December 3, 2020 if I connect the speakers to the pc, the audio works. (only with the vodoo kext installed which I have already tested enpejso also with apppe hda with layout id 5) Quote Link to comment Share on other sites More sharing options...
