I see that the drivers getting loaded are the ALSA drivers. You are trying to create the nodes which usually the OSS applications use to talk to the OSS audio drivers. Unless you have the OSS emulation enabled in the kernel/user space, you can't use the audio device through these nodes. Use some ALSA application. Refer to ALSA website for creating your own sample application. Also you will need to create the device nodes for ALSA and also place the config files accordingly. Please someone correct me if I am wrong.
