recording seems to be working OK but:

I vaguely remember something about full-duplex on sounblaster not
being very good, i.e. there's something wrong when using it but don't
remember what (bitrate being forced to be very low or something along
those lines).
Which soundblaster? The "original" ISA soundblasters were like that, and the
"soundblaster PCI" cards with the ens1371 chipset have asymmetric sample
rates for playback/capture, but I can overdub with my SBLive platinum and it
sounds normal.
I don't remember what I read exactly (and google didn't help) and
which card exactly it applied to. I have soundblaster live! platinum
(with live drive). What software do you use? Anything specific that I
need to set?
However I
can't find any information on that subject now (I tried
google and creative site), does anybody know details and/or have some
pointers to relevant docs?
system: debian unstable, 2.6.5 kenrel (with alsa), sounblaster live
platinum (with live drive).
How do you have the mixer set up?
Which input are you recording from?
What mixer app are you using?
Line LiveDrive, Line LiveDrive Capture,
Line2 LiveDrive 1, Line2 LiveDrive Capture 1
are all the way up, guitar pod (line6) is connected to two rca
connectors on the live drive. However I was recording mono only (in
audacity) so I guess only one of them was recorded.
when recording only (no playback at the same time) the recording is
OK, when I play click track at the same time the recording is very bad.
I was recording at 44kHz, thought that might be a problem so I
switched to 48kHz but then there's no full-duplex at all (i.e. the
already recorded stuff does not play when I record).
is this a problem of my setup or audacity? (I can't get muse working,
it hangs whenever (trace reveals it's reading from some pipe) I try to
save (which is required to create audio track)). Any other simple
recording programs (that would make it possible to play the previously
recorded audio (aka full-duplex aka overdubbing)?
