Judging by the error message, it's a known limitation. You are welcome to work
on a fix, or pay the develoeprs to fix it, or offer a bounty that might
encourage someone to work on it, or wait until it gets  fixed.

Meanwhile, convert the file to mono and try again.

Sox should be able to do this, for example.
