My monitor's speakers (Asus VG247QA1) suddenly stopped working. They still show up in windows and the sound bar still moves when something is playing but there is no sound. I tried plugging in other audio devices and they worked when I click the test button in sound settings.
When I test the monitor, nothing happens. I tried reinstalling drivers and it didn't work.

It's less than a year old so it shouldn't just fall apart like this. I also checked OSD and the volume was at 100 and wasn't on mute.

Please help.
