Can't confirm on Delta 1010 series, but this is/was working on Terratec 
DMX6fire and STaudio DSP2000 (other ice1712 cards) since at least about Alsa 
1.0.12.  More people have the 1010's, so I would expect it has been working 
on those.  However I do seem to remember some relatively recent changes 
related to external wordclock on the 1010; maybe it has been broken?

@Jonas - are you using 'envy24control' to toggle the settings?
