Thanks. I already knew the right click to settings. The list shows 5 options, but instead of the ‘speaker setup …’ option, that you have shown, I show, ‘spatial sound (off)’. However, I have now found a fix. I have connected the speakers to the headphone socket, which work ok. And now I can hear ATC loud and clear. Connecting the speakers to the speaker socket affects the ATC to be very faint, why, is a mystery? Just to say that I found a ‘Asus Republic of Gamers’ sound setting, and that is set to Stereo.
