I just bought a Delta 410 PCI and I hook my Behringer ub2442 to the inputs, and I run RCA outs to a speaker set-up....

The problem is that some times I get a crackling sound in my recordings, and I thought it was mic placement at first but I ruled that out. I tried recording in a couple different audio programs but still, some times there would be a crackle when the audio played. I come within -10db - 0db in the recorder, and my mixer is set with the channel gain 3/4 the way up, fader level at -10db - 0db, and main mixer volume between -10db - 0db...... I'm barely able to get a good signal without this clipping, but my board is not clipping and my programs are not clipping... is it the sound card? If anyone has some help, maybe just to tell me I need to set better levels, please let me know.

Wich microphone and what do you record?
Have you tried recording a sine wave at 0db?

hey man,... can be lots of things...

...PCI Latency on bios above 32 cycles
..."problem solution" fader on screen setup full to the right (move full to the left)
... IRQ problems ... see on system setup if you have any IRQ shared with another card.
...System sounds enabled... (disable them)
...Under win2000 or XP... maybe you have "optimization for applications" instead of "optimize por background programs"
...Maybe you dont have installed your mainboard drivers

:) Hope it helps :) let us know :)

Alright well I do believe the problem is solved.

I am inexperienced with using my equipment, but what I did was turn the mixer channel gain all the way up, channel fader a bit under 0db and main mixer fader set around 0db... I had to turn the STEREO FX RETURN down to nothing to remove any FX my board would create...also had to compensate for the extra signal db my board EQ creates...

I get a hot signal that doesn't clip, for guitar and vocals, on this setting. The only thing now, is that my Acid Pro program is giving me a bad signal. Cool Edit Pro works beautifully to record, but if I switch programs to record I get that crap sound... which sucks because I use Acid to line my tracks up and record in sync... I have no idea why one program works well and the other is distorting my signal...
