>Description:

	Audio play program cannot control the speaker volume 
	on Ultra 1 using cs4231 driver.
	
>How-To-Repeat:

	play mp3 file with mpg321 or amp with varying volume.

>Fix:
	The reason was that cs4231 driver didn't register 
	audioNmaster, so user-level ioctl() to control volume 
	without specifiying index was ignored by 
	general audio driver.

	This patch solved the problem. I tested with mpg321.
