Roger that. My problem was just that the volume level was always "too low"...not imperceptable too low, just too low if outside and there was ambient noise, it was tough to hear. My Motorola Q faired better in this regard, as well as other phones of mine.

Well I've given up...hit a snag, or rather, a thicker layer of clear plastic, that I don't want to force. Here is what I have now, coming from my first attempt posted above:

- I started by trimming away the first layer of "black" plastic, which revealed a thinner layer of clear plastic (left side of the expanded slot)..




- Here is a clearer shot...this is what I was going to leave as added protection, but opted for "full volume".




- Here the tip of the knife is under the thin layer of clear plastic (sorry for crappy shot).



- Here is where I gave up...tip of knife is pointing to thicker layer of plastic, that I don't feel like clearing out...right now. I think I can see the edger of the speaker, based on what the OP identified.





The (2) angled cuts at the top of the last pic are just superficial to my screen protector...hopefully. The cavity bottom is kinda goopy...remenants of the glue that I can't seem to scrape out. All I know is that the volume level is much more "comfortable" now. I can actually hold it 3" away from my ear, and hear perfectly with the TV on.

As always...YMMV.
