hi
I am under KNOPPIX 3.6 (kernel 2.4.27) HD install, debian mode

I though my sound was working fine (it's ok for radio, audi CD, etc) but no sound with rosegarden4 or Muse.


a lspci gives :

I have tried playmidi, but got the following message :
open /dev/sequencer: No such device or address


I have also tried timidity, error also :
timidity: Can't read any configuration file.
Please check /etc/timidity.cfg

any idea would be welcome
