No, that was actually really a good advice. You should try to bisect it.
It doesn't take that long (I assume you are cross-compiling instead
of doing native builds), also Linux maintainers are generally doing
a very good job ensuring the tree is bisectable.

I would do it myself, but so far I never have set up my N900 to play
any audio and I don't have any reference points between "good" or "bad".
