[SFLphone] Making it work out of the box

Thu Jun 25 10:59:32 EDT 2009

Hi Andres,

We really appreciate your interest in SFLphone. 

Could you please specify what SFLphone version you are testing ?

From our own tests and all the feedback we have been able to gather, the
Pulseaudio interface is known to work well. We made some modifications
recently though, that unstablize the audio layer. 

From what I see on your debug message, it seems that an underrun occcurs
and after that, you have no sound anymore, am I right ? Do you have a
custom Pulseaudio configuration on your system ? Can you see anything
weird with the pavolumecontrol tool ?

We'll do our best to make it work for you.

Emmanuel
