Easy one-line fix: the hifiberry_digi driver is not going down to 32 kHz audio sample rate (the lowest for S/PDIF), however the underlying WM8804 codec driver supports and advertises 32 kHz. This was inconsistant, resulted in out-of-pitch playback with 44.1 kHz because the application was thinking it's playing 32 kHz.
With this fix, such problems are gone, tested with aplay and mplayer, 32 kHz plays well. Below, mplayer does correct upsampling, before it was mislead.
