can't find sound device

["Georges BETHENOD" <gbethenod (at) siteli.fr>]

Hi,

 

I am using Fedora Core 3

I use GnomeMeeting to make H323 connection and everything goes well

but when I write my own application with OpenH323, I can't find a sound device

    PSoundChannel::GetDeviceNames and PSoundChannel::GetDefaultDevice return empty string (for player and for recorder)

Does I need to initialise something in PtLib ? to recognize sound device

 

Thanks
