I am not sure what the accent of なんの意味もない would become.

I would guess it would be な\んの・い\みも・な\い. Because なんの is [な\んの by
itself](https://ja.forvo.com/word/%E3%81%AA%E3%82%93%E3%81%AE/#ja) (see
comments for this particular audio).

  * In [this audio](https://vocaroo.com/1h1MOG0pQjDx), I think it becomes なんの￣・い\みも・な\い.
  * In [this audio](https://vocaroo.com/1flqpCauW4u6), I think it becomes なんの￣・い\みも・な\い
  * [This](https://vocaroo.com/164dAE5yGJGq) sounds different, but I would still interpret it as なんの￣・い\みも・な\い

Does this happen or am I mishearing those?

answer
なんの is pronounced as なんの【HLL】 when it means "of what", but as なんの【LHH】 when
it's used as a [negative polarity
item](https://japanese.stackexchange.com/a/16060/5010) meaning "no(thing)".

  * なんの【HLL】話ですか？  
What are you talking about?

  * なんの【LHH】役にも立た **ない** 本  
a completely useless book

Similarly, だれの/どこの can be read as だれの【LHH】/どこの【LHH】 when it's a negative
polarity item.

  * だれの【HLL】帽子？  
Whose hat is this?

  * だれの【LHH】せいでも **ない** 。  
だれの【HLL】せいでも **ない** 。  
This is no one's fault.

  * どこの【LHH】国のものでも **ない** 不思議な言葉  
どこの【HLL】国のものでも **ない** 不思議な言葉  
a mysterious word used in no country
