alsaconf tells me no soundcards found. But, as I said earlier that the sound works when I play a CD. So I suppose the sound card is configured. It seems to be a wierd problem. dmesg shows this Advanced Linux Sound Architecture Driver Version 1.0.4 (Mon May 17 14:31:44 2004 UTC). ALSA device list: #0: ALI 5451 at 0x8400, irq 5 Any suggestions please.
