I'm afraid this is on the hardware side.
I recently tried this card on Windows and encountered very similar
symptoms.

Hi,
I just bought an Audiophile 2496. Unfortunately, it does not work as
well as I imagined. Here are the symptoms :
* Simple listening (no jack, just alsa):
- when I route PCM outs directly to HW outs, I here "cracks" on the
right side (I don't know the precise english word to describe the
noise, see below for example)
- if I switch the RCA cables, the cracks change side
- when I route the digital mix to HW out, I don't hear cracks
* Recording (jack, no xruns):
- I can record my guitar (I use the RCA analog in)
- I still hear the cracks while I play and in the recorded sound
(example :http://manu.mindslicer.com/export.wav). These cracks are
very similar to what I hear when I listen music without jack (with PCM
out -> HW out).
I tried with different sets of cables and headphones.
What do you think ? From what I heard, I doubt it is a
software-related problem. A lot of people use the Audiophile without
problem. Moreover, switching the RCAs switches the side of the cracks.
I just wanted to have your opinion before sending the card back. Could
it be a configuration issue ? Is it a problem with the
chair-to-keyboard interface ?
Thanks in advance for all the advices you can give me.
Cheers,
Manu
