Hopefully you can make some sense of what I wrote hereĪnyways, that's all I got. Repeat the procedure for the input audio device settings. A common mistake is unknowingly having a Bluetooth device connected, so audio plays to that instead of through your Mac’s speakers. Click the correct output device for your audio. The HDMI audio support is built in now, I think, but it didn't used to be, and you'd have a heck of a time getting it workingĪnyways, that's all I got. Go to the Apple menu and choose System Preferences. Click the Output tab, then select the built-in speakers. From the Apple menu, choose System Settings (or System Preferences). If you hold down the option key and click on the speaker icon at the top of your screen, it'll show you all audio (sound) inputs and outputs in 1 list. First, disconnect any cables from the USB, Thunderbolt, or 3.5mm audio ports on your Mac. If I do plug something in, Digital Out changes to Headphone, but Internal Speakers is still not listed. The only option I now see is Digital Out, but I have not plugged anything into the output jack. You could try running Audio MIDI setup which would allow you to set the audio inputs and outputs for your MacBook pro. When I open the Sound Preferences Control Panel, my MacBook Pros internal speakers are no longer listed as an output device. Much of the time, this takes care of the problem by. The safest way to do that is to simply run a jack in and out of the port a few times. Weird, huh ? Apparently it depends on the country you live in, or where you bought the monitor, because in Canada, they don't include it.only in Canada, eh ? Apparently the USB-C standard does support audio and video, so you'd have to tell your macbook pro to do audio out via the usb port. The solution is to force the sensor to do its job. They throw in an HDMI cable and a full size DisplayPort cable (no miniDisplayPort, though)-not a real deal-breaker, but no usb-C cable, even though that's one of the cables you need to fully use the monitor. that is-LG is kind enough to include a usb-C to A gender changer, but no USB-C cable is included. I have an LG Monitor as well, the 43 incher (yeah, I know, haul out the world's tiniest violin for me, right ?) and I had the same initial problem you might have had.
