Now that would be shocking I'd say. Since Suse 8.0 the ICE1712 was
always the most reliable chipset one could possibly find for Linux. So
that would be a major regression and should be a show-stopper for alsa.

BUT: the link points to a bug that affects puls audio and it affects it
with a EWS88MT wich is one of the not-so typical ICE1712-cards like the
EWX or the MAudio Audiophile and Delta-Series.

So how about these cards and alsa/jack? Any trouble out there with
bleeding-edge distros?
