Lost sound again

Yesterday I had issues with sound on MP3 and found out it was because of the USB thing. That was fixed. Today, I can’t get any sound anywhere. Not even from playback after recording so I don’t know where to cut my songs since I can’t listen to anything.

Please help

Thanks

If your USB thing is attached, then it’s probably the same problem. See here how to fix it: http://manual.audacityteam.org/o/man/faq_playback.html#usb
