+     To over come this, samples are copied into the tram and a special dsp patch copies
+     the samples out and generates interrupts when a block has finnished playing.
+
+  Method 2 : Interpolator bypass
+

+     (including the emu10k2 (audigy)). This allows us to use the regular, and much simpler
+     playback method.

+  In both methods, dsp code is used to mux audio and passthrough. This ensures that the spdif
+  doesn't receive audio and pasthrough data at the same time. The spdif flag SPCS_NOTAUDIODATA
