[SFLphone] Audio problem with snapshot 20100219

[Albixman]

I'm using Ubuntu 9.04 64 bit and SFLphone nightly to have the
network-manager support.
With the upgrade to snapshot-20100219 the quality of the conversation
decrease suddenly.
I'm able to hear perfect the other person, but my voice arrives at the
other person distorted, with a big delay and with the the word
dilated.
I've tried also an echo test and the problem is still present.
Reverting back to 0.9.7 the problem disappears.
Have you experienced something similar?
Thanks.
