This has been asked again but none of the answers apply because I've tried them all:

  • My MacBook is a 2013 Retina Macbook Pro, so it supports audio through HDMI
  • the HDMI cable is plugged directly into the HDMI port (no adapter)
  • the monitor has speakers, and their volume is to 100% (Asus PA248Q)
  • I've selected the HDMI audio output in the system settings
  • I've tried with a different HDMI cable

But still no audio through the monitor's speakers. What am I missing?

FYI, the audio works fine in any other case.

From what I can tell from reading the Specifications Page, there are no speakers built into this particular monitor. There are however, two different audio outputs: HDMI 1.3 and 3.5mm headphone/speaker jack

The easiest way to test this out is just get a cheap set of speakers or a headset with the 3.5mm jack and plug them in. If it works, you know all is well with your setup - you just need speakers.

    Oh my god thanks for reading that page correctly, it seems I wasn't able to do that. I assumed the jack port meant "audio input" (but it says right there "output"). I just bought jack cable today and tried it out: it doesn't work as an input. So, you are definitely right. In my defense the back of the screen looks a lot like speakers :) Oct 29, 2016 at 17:53

If the screen is connected and switched on, you can select the speakers of your HDMI screen in System Preferences > Sound > Output.

Or if you have the audio volume button in your menubar, you could select it through OPTION + click on audio button. Then select the output device.
