If you’re trying to use your HDMI port and there’s no sound coming out, don’t worry – it’s a common problem. Here’s how to fix it. First, check that your HDMI cable is plugged in properly. If it is, then the next thing to do is go into your System Preferences and find the Sound settings. In the Output tab, make sure that your HDMI device is selected as the default output device.
If you still can’t hear any sound, try restarting your computer. If that doesn’t work, you may need to reset your PRAM or SMC. To do this, shut down your computer and unplug the power cord. Wait a few seconds, then plug it back in and turn on your computer. If you’re still having trouble, there may be an issue with your HDMI port. Try using a different HDMI cable or port, or try connecting to a different device. If none of these solutions work, you may need to get your Mac serviced.
