I don't think it has anything with your UDEV rules. If i remember
right the /dev/dsp /dev/sequenser and /dev/mixer is devices used with
OSS and I don't think OSS has been used in a default settings with
Kubuntu for several versions. If you still want to use OSS you can
load the drivers:
snd_seq_oss
snd_pcm_oss
snd_mixer_oss

or run the program with the alsa "aoss" tool.

Good luck!
