The default sound system is ALSA and /dev/audio or /dev/dsp (OSS interfaces, deprecated in Linux) is only an emulation layer over ALSA -- and not even a fully functional one, at that. The default ALSA device is "default", and if you install mpg123-alsa, it should Do The Right Thing without requiring any options.

snd_pcm_oss provides the /dev/dsp and /dev/sound/dsp stuff. Blacklisting those modules does indeed remove the devices. alsa-oss is simply a program that hooks calls to e.g. /dev/dsp and emulates the OSS api using alsa. In that case you do not need /dev/dsp, etc.

This will map the /dev/audio or /dev/dsp file to the new Audio Server system. Fire up the terminal and get into root mode with sudo su. Then, I'm going to cat /dev/urandom and pipe the output into padsp and use the tee command to send the data to /dev/audio. You'll get a ton of garbage in your terminal, so you may want to redirect to /dev/null.

sudo cat file.wav > /dev/dsp. The reason you continue to get "permission denied" is that your shell first tries to open the /dev/dsp device for output, before running the command (which is sudo ). To have the shell open the redirection with root privileges, you would have to do something like: sudo sh -c 'cat file.wav > /dev/dsp'.
