[pulseaudio-discuss] Pulse Audio 4.0 gets killed by 300 Hz tone...never recovers

[Robert Krakora]

OK, I took the 300HZ.wav file and retested locally with Asterisk 11.4 out
of the equation.  It is sampled at 44.1K and motorboats with
'resample-method' set to any value.  If I convert the file to 8K it then
plays fine with 'resample-method' set to any value.  I am confused.
