Say Y here to include support for Ensoniq SoundScape PnP
Say Y here to include support for Ensoniq SoundScape
soundcards.
The PCM audio is supported on SoundScape Classic, Elite, PnP
and VIVO cards. The MIDI support is very experimental.
To compile this driver as a module, choose M here: the module
will be called snd-sscape.
