i'm using reaper to record my band. it's been working fine until recently when it won't pick up my playing. i'm running a microphone -> mixer -> mic input on my laptop but no sound is coming through. it's also not working on my other recording softwares (kristal and audacity). when i checked the control panel, a strong signal was coming through the external mic. help?
Sounds like a driver issue.

If you're plugging into your Laptop's microphone; not the best method may I add! Make sure the driver is set to your computers sound card, which is usually a Raeltek I believe...
