Yes. The connectors are of the same kind that comes with the headphones. I checked the cable with a technician and it was OK. Nevertheless, I'm told that when the cable is plugged into the line-in jack and the other end of the cable is unplugged, I should ear noise when touching the connectors of the latter end with a metal probe. I don't ear that noise (out of the columns nor the headphones).
Actually, the thing seems to work now with another O$, but not with linux (it wasn't so before, can't figure what changed).

I meant I connected the headphones to the walkman (or to the TV) with the said cable in the middle, for testing purposes (the cable is actually a male-female extension connected with a male-male one; I checked both pieces).

I have analog (3-pins) cables from the (internal) analog connector of the drive to the corresponding internal connector in the card. I use Kmix for mixing, and also tryed smixer.

I'm beginning to think that this is a driver problem. I would try alsa if I knew whether it's supposed to work with Audigy2 (I couldn't get any clear information about this, and uninstalling alsa in case it doesn't work is a real pain, not to mention the time KDE needs to compile...).

Thank you for your help,
