Hi All,
Hopefully everyone isn't receiving this twice, I think the first
one was blocked due to being to large (I've trimmed the output below,
hopefully not too much though!)
Apologies if this is duplicated.

Hi All,
I've setup pulse audio to stream music from my iPhone (connected
using BlueTooth) and output it, using module-loopback.... This is working
fine, the only issue I have appears to be related the bitrate/timing
etc... The music is very crackly, and is playing back too slowly.... I've
tried changing a number of options, but haven't been able to resolve it.
I've tried lots of different combinations of the 'rate' option, but none
helped... Any help really would be much appreciated, please find debug
output below, along with the script I'm executing:
Script:
#!/usr/bin/pulseaudio -vvvnF
