Every day there seems to be something new to troubleshoot (in general in my FS9 setup - not all with FDC/PF3 of course!!). Actually this is not so new - it's been a week or two, and before that I had the problem very occasionally, so I didn't bother too much about it then: I held off posting about it now until I was sure it wasn't a one-off, but it's starting to happen most flights now, so I'd appreciate some help.
At some point during a flight (not sure yet if it's confined to just certain aircraft, though I don't see how it could be), the sound of the FDC pilot and co-pilot suddenly starts stuttering, breaking up and becoming distorted - what I can only call 'hyper Dalek-like'. The problem comes and goes as I fly on but some phrases are so stuttery they are pretty much missed entirely.
I would put it down to a PC issue, and maybe wouldn't post here (I have so many threads here already, I'm starting to feel bad about posting any more), but the thing is that all the other sounds, FS9 and all ATC communication in PF3 continue quite normally whilst the FDC voices are breaking up. The wav files themselves are OK as far as I can tell, as next time in FS9 the same sound files may show no such playback problem (and the few I have tested are OK in a media player too).
Anyone else encountered this? Any ideas what the problem might be? Thank you.
