This patch adds support for audio part of the Ensoniq SoundScape VIVO cards. The MIDI part is not supported.

Signed-off-by: Krzysztof Helt krzysztof.h1@wp.pl ---

This patch requires the previous sscape patch (extension to new settings).

I created waiting loop and the previous magic write after the code in the OSS driver. The whole detection is magic from the OSS driver.

The MPU is not created on VIVO cards as it does not work.

The linear frequency setting for the AD1845 does not work for me (the frequency is incorrectly set). IMO, it is better to move extended AD1845 support into the CS4231 library.
