Strange question here, but I am hoping someone understands what's happening and
can save me hours of debugging.
The application interface I'm writing uses the threaded mainloop. I
asynchronously read into a ringbuffer from which I can synchronously read from
in specific frame blocks. Being a so
I ran into this issue also. Once a buffer underrun occurs, you won't get any
more write callbacks until you satisfy the prebuf attribute value. Setting it
to 0 certainly will work around this if you don't need a playback buffer.
However you can use the buffer underrun callback to write the requi
ff data between read and
write callbacks, things are running smoothly.

All,
I'm working on a basic asynchronous read/write program to understand the API
before applying it to another piece of software. On a read callback I create
(or add to) a buffer, and then on write callback I write back as much of it as
allowed. The code follows pacat.c and several examples I'
Switched to using tunnel mode on the local machine and I am unable to reproduce
the problem. This is definitely a pulseaudio bug using a direction connection
with simple API over a network.
I will file a bug report.

while running the SDR application... after a few seconds of stuttering I get
nothing but full volume white noise.
Unsure of what other tests to run at this point.
Thanks,

All,
I've been trying to pin down the cause of an audio issue with pulseaudio and an
application called Quisk. This is a software defined radio application that
uses I&Q sampling (L&R channels) via a sound card. The SDR radio has both audio
in and out going to a Wolfson pi audio card attached t
