I don't think we should alter the $('audio').checked attribute at all, even if
it's not supported in Chrome (unless the spec says so).

Please modify the error messages displayed when invalid constraints combinations
are attempted (possibly try to help the user by stating which combinations are
currently not supported).

Done.
