yes im aware alsa needs the nodes in that folder which would be fine for one of the devices i am developing for (nokia n810) whoes audio codec creates said files but the other device - nokia n800 does not as although alsa detects the audio system it does not create pcm devices as i think everything has to go though the dsp to get sound on the 800 ?
