That would be a perfect solution, but I'm not a C developer and have no idea how to approach it.

BTW, it would be nice to support more advanced syntax in profile file like this:

> front-left,front-right,none,none,none,lfe
This would allow to avoid moving LFE to wrong position too without code changes.
