Replaced my old Dell 700MHz Lab machine with a Dell Model 4500 (2.0GHz) and to save money went for the integrated sound board (using it as a server not much need for audio) It is an Intel chipset (Analog Devices ADI 198x Integrated Audio) based sound card that uses the SoundMax drivers. You see them alot on all level Notebooks, all level business machines and low end home desktop systems. The drivers are out for all MS OSes, easy to find. But in the Linux world this driver does not yet exist. Did my searching Latest Redhat and Mandrake do not have the driver, lots of asking for it but no solution. I'm running Redhat 7.3. Audio Chipset Vendor says "what you see is what you get", Dell says nothing at all. More the fact that I have a component without a driver is more annoying to me than it really affects my ability to use the machine without sound. But until Linux has better support from the hardware vendors for these drivers, it will have a hard time getting main stream. The real moral of the story is that I shouldn't have skimped on the $20-$30 and should have gotten a regular SB PCI card. I skimped on both video (Rage ATI 128 with 32MB Ram) and audio to keep the price down (remember lab server, 512MB ram more important than anything). If I goto comp-usa I may see if they have a cheapo SB clone Sound card and may put it in and see if it works???
