>Description:
	$ repeat 100 cat xxx.au >/dev/audio.
		or
	$ repeat 100 cat xxx > /dev/dsp.

	They work well, but 

	$ tracker str32.mod

	It works well at the first time, but I get kernel messages
	at next open of /dev/dsp.

		isa_dma_acquire: channel 5 already in use

	$ xanim sound.wav

	It works well at the first time, but I get kernel messages
		as following repeatedly(continues to play sound).

		isa_dma_acquire: channel 5 already in use
		Sound: Reset failed - Can't reopen device

	dma16 chanel number is 5, that of dma8 is 1.
	I guess it's because of Confusion between dma8 and dma16 chanel.

	I have not seen such errors till 2.2-SNAP1014.
	Then Jumping to Beta, I get the errors
	I import /usr/src/i386/isa/sound from 2.2-SNAP1014,
	but can't resolve.
