I have no problem with the sound using Fraps, and I have a very exotic sound system, the KX Driver. I think with some investigation you will be able to fix your sound problem.

Mick I sent 2 mails to Fraps and recieved 2 replies, the last of which said that the lack of sound could be cured by downloading the new Realtek drivers.I checked the Realtek site and found I already had the latest drivers but not the latest "audio codecs".I then uninstalled Fraps, installed the new audio codecs, went into Realtek and tinkered with every setting I could find, all to no avail.I just looked at the KX Project site, and even if I could understand what it meant, it appears it only applies to the States.As a true Brit I know I should be a fighter, but on this occasion I think I will hang my head,admit defeat and chuck Fraps in the Recycle Bin.
