I can confirm this issue (on Jessie), and would like to add that I'm
experiencing it in the opposite direction from the other posters (i.e. I
already had libaudio2:amd64 installed, and run into the conflict when trying to
install libaudio2:i386). This is to be expected given the nature of the
conflict, but thought I'd contribute anyways in the event it's useful:
Preparing to unpack .../libaudio2_1.9.4-1+b1_i386.deb ...
