AORUS, ASUS, LG Monitor – HDMI Audio Not Working with PS5? Here's What to Do

The AORUS FO32U2 Pro is a high-end gaming monitor made by Gigabyte, a well-known brand in the world of gaming hardware. Similar issues have also been seen with other premium monitors from companies like ASUS, MSI, LG, Samsung, and BenQ. But in this case, the focus is on a specific problem that many users have faced with the AORUS FO32U2 Pro — no audio over HDMI when connected to a PS5.

The audio works fine when a PC is connected using DisplayPort, but when a PS5 is connected using HDMI, no sound is heard — even after disconnecting the PC and using HDMI alone.

If this issue has been experienced by you, don’t worry. It is usually not a sign of a faulty product, and it can be fixed with the right steps.

What Might Be the Reason?

This problem is often linked to audio compatibility or signal issues, rather than hardware failure. While Gigabyte AORUS monitors are designed to support HDMI audio, some signal format settings used by the PlayStation 5 may not match the monitor’s default setup.

Such issues are not unique to AORUS. Similar audio concerns have been reported with ASUS ROG Swift, LG UltraGear, and Samsung Odyssey monitors when connected to gaming consoles like the PS5 or Xbox Series X.

Steps That Can Be Taken to Fix Aorus Monitor Audio not working

1. Adjust Monitor Audio Settings

Open the monitor’s on-screen menu (OSD) using the joystick or buttons.
Navigate to the Audio settings section.
Make sure that HDMI Audio is enabled and not muted.
If the monitor includes a headphone jack or audio-out port, try connecting headphones to check if any sound is being passed through.

2. Change PS5 Audio Output Settings

The PS5 may be using an audio format not supported by the monitor.

Go to Settings → Sound → Audio Output on the PS5
Set HDMI Device (TV) as the main output
Then go to Audio Format (Priority)
Choose Linear PCM or Dolby (test both)

This setting has helped users with ASUS TUF, MSI Optix, and even BenQ MOBIUZ monitors solve similar issues.

3. Try a Certified HDMI Cable

Make sure a high-speed HDMI 2.1 cable is being used
Try another HDMI port on the monitor if available
Some cheaper or older cables may not support full audio output, especially with 4K gaming

4. Update Monitor Firmware

Go to the Gigabyte/AORUS official website
Check if there is a firmware update for the FO32U2 Pro
Firmware updates can often fix bugs, including HDMI audio problems

This step is recommended for monitors from LG, Samsung, and MSI as well, since audio issues can be resolved through system updates.

Final Advice

It’s normal to feel concerned when a brand new monitor has a problem — especially from a top brand like Gigabyte AORUS. But often, such HDMI sound issues are caused by minor settings mismatches or cable issues. Models from ASUS, LG, and BenQ have faced similar troubles that were fixed without hardware replacement.

If none of these steps work, it’s recommended to contact Gigabyte Support for further help. They may offer extra steps or confirm if the unit needs to be exchanged.
