No, I checked that--I opened kmix, cranked the volume up on just about everything, and still didn't get any sound. Here's the weird part: if I pop in an audio CD, I can play that just fine. But if I want to play an mp3, wav, or other audio file, it doesn't work. Furthermore, when I restart arts, I get the '/dev/dsp busy, using null device' message. This is true for both root and an ordinary user. I tried to see if Knoppix would behave, but it gives a device error; I don't have it loaded now, but it was something like, '/usr/lib/...path_to_kernel_module/via_ac97.o device not found' or something like that. In other words, Knoppix was able to detect the sound card--otherwise how could it have known that it requires the via_ac97 (or whatever it is) kernel module--but when the kernel module attempted to access the device, it didn't work. This is rather perplexing. The system detects the sound card, lsmod shows a slew of drivers for ac97, so drivers are getting loaded, but it doesn't work. I don't think there are any IRQ conflicts, since lsmod shows it as IRQ 18; what are some ways I could find out if it is a hardware problem or a conflict with another device? :Peter
