Thanks, I hadn't seen that so clearly stated before!

OK, but do you need to be so imprecise about this? What can't there be a definitive solution? > "Hiss and Etc" I didn't hear about, but I don't think kernel or hardware > world can cover for any of it on existing device.

I must admit that I've never heard the "hiss" either, so I don't know exactly what it means... but someone that I called a few days ago said there was a strong hiss on the line. (In retrospect, I should at least have tried calling again, as maybe it was just a line issue.)
