Record sound from PC and send as voice clips?

are there any ways of recording sound from your pc(not from mic) and sending it through voice clips?

no, unless you somehow record using the Line In port

If you have a working ‘Stereo Mix’ or ‘What U Hear’ input in your sound card drivers, you can set Messenger to use that input the Tools, Audio and Video Setup wizard.

Personally, I use Voicemeeter for this sort of thing, and just set the A/V wizard to use the Voicemeeter input.
