I'm having some issues with PiFm on the raspberry pi zero - I found this thread but nothing to alleviate my problem. PiFM not working for me

I installed PiFm on a raspi-zero and it seems to be nearly working. I can get only a single tone (or sometimes random sounding noise) on the frequency that I have chosen but nothing is intelligible. I am able to adjust the frequency, so that suggests the hardware is working to some level. I can get some change in the tone based on adjusting the sampling rate but I've ensured I'm matched up with the sampling rate at the high and low end for various sounds.

I'm guessing it might have something to do with the pi-zero vs the regular editions. I am away from home right now so I don't have an o-scope handy or my micro-hdmi to test the regular audio. Just seems like I am missing something fundamental here any near term help would be most appreciated.

I've played the sounds (wav and mp3) on my pc and they seem fine, also i've checked the permissions, gpio status, etc as others have suggested.

Thanks in advance to any suggestions.
