RadioFeed 32 bit in Darkice

[N2ZPY]

Have my feed now up and running on a Pi3. It is a stereo feed. I had to move the sample rate up to 48000 to remove a warbling sound in the background. I can still slightly hear it when a transmission is being broadcast but not bad. I can only get the bits per sample field to use 16 on both sections. It will give me an error if I move to 32 bits. Any ideas on this?

Thanks!
