Sorry to be such a nuisance.
Oh, you're not. If *I* only knew how to help here. And you shouldn't do it on your own either ...
The fact that the dropouts increase at a higher samplerate -as you described it- says enough I think. Do note that the upsampling comes right after XX and is done by the OS. Well, in your Vista case of course.
I'm not sure what to do with it (because it should be the drivers) ... but can you perhaps recognize that the dropouts occur each time at the exact same place (in a track) ? Again, dunno what to do whith it, but who knows something shedds a light ...
nothing on the device manager is actually called a motherboard!
No ... this is about the various chips which are on the mobo, and *they* need upgrading. But I really never done it.
Chances are high that #3 goes around your issue, but then first #3 has got to work at your systems.
Note though that XX itself (which would be the case then) doesn't go higher than 88K2.
Just don't give up. Today I suddenly found solutions (C++) for things which I couldn't find for 4 months ...
