are all the way up, guitar pod (line6) is connected to two rca

audacity) so I guess only one of them was recorded.
OK my livedrive is a early revision and the RCA's are S/PDIF,
but I use the 1/4" line/mic in. Set to line it's stereo
Line-Livedrive (record ready - set to unity). It's associated capture
fader is also set to unity. Capture (main) is record ready and at 0
Things that cause distortion/phase cancellation/"howlround" (feedback with
british EQ ;):
Bringing up the main capture fader unnecessarily
Bringing up either of the AC97 faders

I haven't had to do anything special, but the last time I overdubbed a day or
two ago, I had the playback channels both frozen and muted, so I don't know
if I'm missing something about the problem as described by whoever had the
details.

recording seems to be working OK but:
in audacity when I record the track it sounds OK
however if I generate click track and record then (the click track is
playing while I am recording) the recording is really bad (noisy, low
quality).
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. 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? 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.
Where is the click routed?
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,
Well, something to keep in mind is when you add a track the output is summed,
so you might have plenty of headroom until you add the click.
I've noticed a tendency for the SBLive sound to start sucking hard once it's
had a few transients bashed into the ceiling. I could be wrong as to the
particular case, but you should be knocking 3dB off of the source track level
for every track you add to account for the summing when you overdub.
IOW 0dB to the master for 1 track, -3dB to master for 2 tracks, etc.
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)?
Depends on what you call simple. If you were trying MusE, I'll suggest
Rosegarden4. I like Audacity, but the lack of metering really doesn't make it
suitable for recording.
