I have a panasonic TV/VCR combo. The VCR records the video but not the audio.
The audio that plays is from the previous recording. Any suggestions?

You are on the wrong system. In the USA, you should be on NTSC 3.58 or 4.43. In the UK and South Africa, they use PAL-I. Some countries use PAL-DK. France uses Secam. If you are on the wrong setting, your sound will not work. Go into your menu and try that.
