I'm using Suse Linux Professional 9.1 on HP D530 Desktop, and I cannot hear any sound. Everything seems OK from the point of view of the hardware; in fact, I tried installing Windows OS on a disk partition of my PC and in this case the sound works fine. I suspect there is a sort of incompatibility between the sound card and the Linux OS, but looking at YAST, the hardware seems correctly recognized and configured. However, if I try to reproduce a sound, even the bell sound, I don't get any error message, but no sound comes out. The name of my integrated sound card are: 82801EB/ER (ICH5/ICH5R) My office mate has the same Linux OS on a HP EVO D310 and he has never experienced problems with his sound card, which is a 82801DB (ICH4). Anybody can help? Thanks, Beatrice
