Commit 57e5c63007955838043e34c732d224b2cbbb128f "emu10k1: allow to disable the SRC" force hardware use only one rate (48000 hz), but EMU have support two hardware sampling rates (44100 and 48000 hz).
The commit serves for its purpose: it restricts the sample rate only when user specifies to disable h/w resample. Emu chip is driven in 48k rate and other rates are the result of resampling.
In other words, if user doesn't specify the flag, all sample rates are still allowed.
