Your spectrum looks extremely noisy. Wide FM requires relatively high SNR to produce good audio, but even if your SNR is high enough you are probably having a lots of noise distorting the signal. You can compare to this broadcast spectrum I captured using the HackRF Jawbreaker about a year ago: https://www.youtube.com/watch?v=6M4s73M1k4w A few things you can try: Reduce the gain. Move the antenna away from electrical appliances (preferably outdoors). Use a USB cable with ferrite.
