|Music On Console (moc) no longer starts on both my 32-bit and 64-bit aptosid machines. I found a fix here:
https://bugs.debian.org/cgi-bin/bugrepo ... bug=740612
I can't be without sounds until there's a proper fix, so issuing the following command as root brought the music back for me:
root@audentity:/var/cache/apt/archives# dpkg -i librcc0_0.2.9-3.1_amd64.deb
I'm guessing that 32-bit users should change the package name from _amd64.deb to _i386.deb, but sadly my 32-bit machine didn't have the old package still lying around.
Disclaimer: I'm ready to be corrected if that's not a safe way to downgrade a package.
