The lag or delay you are experiencing with the microphone input on Windows 7 when connecting your electric guitar's amp is likely due to the settings related to audio input processing. Here are a few steps you can take to try to resolve this issue:
Adjust Audio Settings:
- Check Latency Settings:
- Open the Sound settings by right-clicking the speaker icon in the system tray and selecting "Recording devices."
- Choose your recording device (microphone in this case) and go to Properties.
- Check the "Advanced" tab for any latency settings and try adjusting them to reduce the delay.
[]Driver Updates:
- Ensure that your sound card drivers are up to date. Outdated drivers can sometimes cause delays...
