You could try upgrading only the libsdl packages to the Intrepid version. Note that we don't know exactly where the bug/fix is (which is why it's invalid and not fix released), so it's really just trial and error. No guarantees that it will work, or that it won't break your sound either.
1) Change your sources.list to use intrepid instead of hardy
2) Update libsdl1.2debian (1.2.13-2ubuntu1), which should also include libsdl1.2debian-alsa (please don't update your whole system)
3) Change your sources.list back to using hardy
Only try this If you're comfortable with modifying your sources.list and you understand the implications of having non-hardy packages installed. Let me know if this fixes the problem.
