Not able to make out the labeling on the port nor see the port below.
On the controller (not the box) is there a 3.5 mm female port for audio? Or any other port for that matter?
The question is really a matter of identifying the options available (i.e., real working output ports - not placeholder "dummies"), determining if you can configure them for audio either directly or indirectly with some adapter perhaps.
What does your User Guide/Manual say? If you do not have a manual go online and downlown the manufacturer's manual for your model number.
Edit Correction: Actually Need 2.5 mm male to 3.5 mm female and not that specific Cablemart adapter. The one solid piece is the real message - apologies.
I would probably go with the first one just as a matter of keeping the adapter sort of "inside" and protected. But the 90 degree bend and dangling cable can be problematic as well. More to get pulled, break apart, twisted. Do not go with the lowest price but a higher price is no longer any real guarantee either.
