I'm having the same problem and I've spend hours with Dell tech support to
understand and resolve the issue...bottom line is they say that for Vista,
Microsoft has basically 'disabled' the ability to listen the what you are
recording WHILE you are recording it. However, this seems inconsistent with
various Vista help text what seems to indicate such a simple task (that
worked find in XP) is possible.
My problem is I don't HAVE any selection like 'Stereo Mix' or 'What U Hear'
on the Recording tab, I only have Micorphone, Rear Mic and Line In (which is
selected).
At first, Dell said if I got a Sound Card that supported 'Stereo Mix', I
could hear while recording, then they said no sound card manufacturers have
developed the drivers. But then I see Vista help text under the definition
of 'Duplex Sound Card' that seems to indicate that if I only had a duplex
card, I could hear what I'm recording while recording.
I would appreciate any clarification or guidance. If I have by buy a new
sound card, fine, but I'd like to have some level of comfort that it will
work.
Thanks in advance
