I'm not a Thunderbird maintainer, so I don't know how
feasible this is,
but perhaps we could create a subpackage like
'thunderbird-sound-support' that has the appropriate dependencies on it.
Then at least someone doing a yum search on thunderbird would notice
that and assume they probably wanted it (if they're hitting the same issue).
Just changing the package requires seems far simpler to me.
