This is a new ALSA driver driver for Rockwell WaveArtist RWA010 chips found
on some (rare) ISA sound cards, such as DCS Multimedia S717.
I wasn't able to get the old OSS WaveArtist driver to work with my card but it
was a great source of information about the chip (as the full datasheet is not
available - only a brief one and a design guide).
However, the OSS driver only supports few of the mixer registers so I had to
install the card in Windows and dump mixer registers while changing the mixer
settings. Then tried what the rest of the registers do and the result is a
fully working mixer which even supports more controls than the Windows driver.
Someone with a NetWinder can add support for it to this driver and then remove
the old OSS one.
