Comment 4 for bug 910940

A check within the Ubuntu Package archive shows that libsdl-sound1.2 has been converted to Multiarch on Ubuntu 12.10.

Since I am not running 12.10 for x86_64 at the moment, it would worth if someone tests this. The aforementioned test with DOSBox can be repeated, applying the following steps:

1. Install DOSBox, x86_64 architecture: sudo apt-get install dosbox
2. Remove DOSBox, but not the dependencies: sudo apt-get remove dosbox
3. Attempt to install DOSBox, i386 arch: sudo apt-get install dosbox:i386

Assuming all relevant dependencies have been converted to Multiarch, no package should get removed on step 3.

P.S. As of 12.10, the libsmpeg0 package (which has also been converted to Multiarch) is not a dependency of libsdl-sound1.2.
