129 Say Y here to include support for Emagic Audiowerk 2 soundcards.

131 Supported features: Analog and SPDIF output. Analog or SPDIF input.
132 Note: Switch between analog and digital input does not always work.
133 It can produce continuous noise. The workaround is to switch again
134 (and again) between digital and analog input until it works.
