[Linphone-developers] "Must catchup" Warning

[Guillaume GOURAT]

Hi,

I have an arm 920t platform (samsung s3c2410) with the last version of alsa
but I use OSS emulation because i have an issue when using alsa native
interface. I have compiled linphone, it work but i have some problems :

I have a lot of "Must catchup" Warning. What is the cause of this warning ?
It appear randomly during the call, or systematically when playing ring or
dtmf.
