If after running alsaconf, you have no audio devices in /dev, then before selecting an option in the myth main menu, switch to another console and then type the following:



and execute the 'snddevices' script at the location found.

This will create the missing dsp, mixer, midi and other devices.

This worked for me in RE50!

Enjoy

any ideas why I would need to do this every time the machine reboots?
if I don't run this snddevices script then I don't hear anything
