I'm afraid that's all I can think of. You may be right about the problem being
with the driver. I had to switch from using my expensive PCI card to using the
built-in sound because the driver would not record in stereo.

You could try building the latest driver - details on the alsa website [1].

Perhaps other people will have some ideas.

Good luck.
