[Openal] repeated "buzz" while streaming with openAL

[Daniel PEACOCK]

Hi Simon,

It would be useful to know at what stage things have gone wrong ... during
capture, during transmission across the network to the 2nd PC, or during
playback.   This can be determined by writing a wave file to disc at the
different stages - e.g write a wavefile to disc based on what you receive
from the capture buffer on the first PC, and write another wavefile on the
2nd PC based on the audio data it receives.

Rather than using 2 big buffers of 88200 you would probably be better off
using more buffers of smaller sizes, e.g use 10 buffers of 17640 bytes.

Also which OS are you using?

Not that this is a solution, but what happens if you capture and send at
48000 hz?
