What about to create the missed file?
My 'dsp' actually looks as follow:
Code:
crw-rw-rw- 1 root audio 14,  3 Apr 15  2001 /dev/dsp
The 'c' at the beginning state it's a 'special character file', which require to be created with the 'mknod' command. Never created this kind of file before.
Another way to create it could be to copy it after booted the live cd.
Notice that the owners are the 'root' user and the 'audio' goup.
