I just installed MX 25.3 Infinity on a Dell Chromebook 3120. I have sound when I pull up YouTube on Firefox, but when I try to run an emulator (tried RetroArch and Mesen), I get no sound.

I've tried adjusting settings and making sure nothing is internally muted. Both apps show up on the audio mixer playback tab, but they just show "Silence."

Any help would be appreciated.
