help
Say Y here to include support for Emagic Audiowerk 2 soundcards.
Supported features: Analog and SPDIF output. Analog or SPDIF input.
Note: Switch between analog and digital input does not always work.
It can produce continuous noise. The workaround is to switch again
(and again) between digital and analog input until it works.
To compile this driver as a module, choose M here: the module
will be called snd-aw2.
