Hi, currently I have Dell G7 7588 running Hackintosh (Big Sur 11.3.1, OC 0.6.9) connected to a Dell Ultrasharp U2419H using Type-C to DisplayPort cable. This monitor has a 3.5mm jack audio out and I use it normally on Windows with an external speaker. But on macOS, I dont see this monitor in Sound device output. The internal sound on the laptop or if I put the 3.5 jack directly to the laptop, everything is okay. So is there any solution to fix it? I already had hda-gfx=<onboard-1> property, also I tried to change other layout-id or use FakePCIID + FakePCIID_Intel_HDMI_Audio but seems not working. [link] [comments] |
