Hello, I installed FC3 a month or so back and have no sound on it the whole time. The current system is a Presario 1621, 233mhz, AMD 64, with an ESS1869 sound card. The computer previously had Win 98 and XP and the sound worked. I try to detect the sound card, and &quot;no sound card is detected&quot; I have looked at the BIOS settings, and they are DMA 0, DMA 1, IRQ 7.... I had 2 modprobe files and one was .conf and the other was .conf.dist. The .conf had only one line of code in it, whereas the .dist file had what appeared to be the default files. I am not sure what to do in order to get this to work. Any ideas? Thanks, TOM
