System: NetBSD 1.2 NetBSD 1.2 (COMMA) #13: Mon Dec 2 18:40:23 MET 1996 i386

	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.

	see src/sys/dev/audio.c

Yes, this is a problem.  But there are bigger bugs to fix right now :-)
