There are no other programs running. Even if there were, my symptoms would then not be localized to playback, but would also show when recording, right? This is very, very consistent. Have you tried recording a long single tone into your Phone-Recording-C item and playing it back through the modem to see if it breaks it up (stutters)? Is no-one else seeing this? If someone will try this and tell me they don't see this, I'll be glad to try a full reload of my PeeCee. But if other people are seeing this modem-playback stutter, then it's probably not my PC, saving me a lot of work in a reload that won't help. > Ingo Dean wrote: > > > > I'm still having problems with ECS 4.0 stuttering when playing a > > Phone-Recording-C to the modem. > > > > What's odd here is that playing the same Phone-Recording-C file to the > > soundcard (Play->VC) sound perfect.
