Dual Soundcard - No Output
Author: Yggdrasil    Posted: 2004-04-20 05:34:47    Length: 18,608 byte(s)
[Original] [Print] [Top]
Hello all,

I've just installed Knoppix without any hint of problems as a dual boot with WindowsXP. I've been a Windows tech support guy for several years now, and currently exploring Linux. I now seem to be having problems playing sound in Knoppix. Both the soundcards (via82cXXX) and Hercules Fortissimo II seem to be detected OK, I've checked the sound in Kmix, and it is not muted. Also Mpg and AVi files have no output, and as I have an external mixer (JBsystems), I can see there is no output signal. I've also run a chmod 666 on /dev/dsp and /dev/audio. I've tried both Alsa output, and OSS, and tried switching aRts soundserver on and off.

Both the soundcards work ok under winXP.

As per forum advisories, I'll put the output of cat /proc/pci; cat /proc/modules; cat /etc/modules.conf and ls -l -L /etc/dsp* in this thread. Any help would be greatly appreciated...cheers
