Audio not working in ES or Emulators

I am trying to run on a Lenovo Legion 5, Ryzen 7, with Nvidia GTX 1660ti. Strangely, the text is not displaying well. (See image)

However, the largest issue is I have no audio whatsoever. Not in ES, or in any emulators. Any thoughts? I've tried re-installing audio drivers - and audio works on everything else I run on the machine.

Thanks

I should have checked this screenshot before attaching it - seems to not demonstrate what I was seeing. Regardless, audio is main concern here.

My dxdiag says I'm running DirectX 12, with no sound issues (checked after seeing FAQ, but FAQ suggests ES sound works, mine doesn't) - however DirectX download link is broken.

Hello

Please add an avatar, and then it will work better

Joke aside, have you try the EmulationStation thing first, or not ?
if yes, can you please try to reinstall VC++ Redistributables x86 and x64 ?

Regretfully, I was so frustrated, yet loving Retrobat so much, that I just started re-installing everything. All audio works now - wish I knew exactly which action fixed. Rendering of fonts is still a little weird in fullscreen - even if I change the resolution to native in retrobat.ini.

Thanks.
