>Description:
	The audio subsystem is hostile to writeonly devices in two ways:
	- it requires that you create dummy functions for the read direction
	(audio_hardware_attach()) check that they are present)
	- it allocates the read buffer unconditionally

	For the 2nd complaint, swap read and write in the above text.

>How-To-Repeat:
	see src/sys/dev/audio.c
