[pulseaudio-discuss] RTP output time between packets

Hmm, didn't find the latency setting. 

On the receiving end I have a small embedded system with a Stellaris Cortex M3 LM3S9B96, and it seems to have problem to receive two packets very close to each other. So if it would be possible to get a more equidistant sample stream, at least during development, that would be nice.

This is the result of vlc sending chunks of audio at a time, probably due to a large buffer from pulseaudio. Perhaps requesting a lower latency helps. (The easiest way to test that is just to open up

As long as the receiving end has a big enough buffer, the delivery of rtp packets in batches should not matter much though, assuming low-latency is nog a requirement. How is the receiving end configured?
