View submission: Question about BH1415F Pre-Emphasis
I wouldn't bother myself, you could change the caps on pin 2 and 21 but this chip still doesn't really have the performance to make the work with it in my opinion. I do think removing them entirely isn't a solution, no where in the data sheet does it show them just floating.
If you actually want good audio quality get a transmitter you can feed an external MPX into, not ones using this chip.

It doesn't show the pins unconnected, but I don't think it matters, the caps partially short the audio to ground, so I don't think replacement is needed (nor possible, those are SMD)
Also, if you know a cheap, functional and one in a case without the BH1415F please let me know
