Re: [Linphone-users] Please include native support for PulseAudio

[Simon Morlat]

Thanks for your help Chris.

Apparently by magic after restarting my pc pulseaudio is now working

I could finally test my pulseaudio support, and it is now working fine,
with a very reasonable latency.
Everyone can now use it by checking out the lastest git sources.
