Here's an odd one: I'm building a computer for a friend and put Mdk 9.0 on it. Finally got the modem to work, but the sound card, while recognized, doesn't play any sound. I've checked all the obvious things: the speakers are on and connected to the right jack, volume turned up, but still nothing. The sound card is built into the motherboard (AC97) and lspci -v shows that it's there (IRQ 18). Kcontrol (Information -> Sound) recognizes it and arts seems to be set up correctly. There was no nasty error message when KDE started, saying '/dev/dsp not available' or anything like that. As far as I can tell, it is enabled in BIOS--what gives??? :Peter
