Some part of video has no sound

I have a wedding video made by professional photographer, This tape plays half way verywell and all of a sudden the sound does not come, after 30 min or so again the sound comeback and tape play good. When I play the same tape in other player the WHOLE tape is very good. The first player is DVD/VCR combo made by Philips 1-1/2 Year old. THe second player is TV/VCR/DVD combo made by Panasonic. Any thought and solution for this any one. The second player is T

For a quick fix, try playing it in the second player and recording it on the first one, so copying the tape. This should produce a working copy for the first machine, because it should be able to play what it recorded. If it works fine in one player but not another, this is probably cause by some misalignment on the audio section of the tape. If this it the case, it will be specific to the video cassette itself and not the footage. The newer player will probably be able to play the tape despite the glitch, in the same way some older CD players can't play home-written CDs.
