Hi Bram, thanks for useful information. I executed pa_devs.exe on my machine and in pa_devs_out.txt I've all devices. I think if I use Pa_GetDeviceCount in my project, it will list correctly devices. I'm working on softphone GUI, on Visual Studio C++ 2005; in my project I call libpjproject-i386-Win32-vc8-Debug.lib, compiled in my machine on pjproject-1.5.5. To use Pa_GetDeviceCount, I must re-compile libproject with SVN trunk ? I probed this: #include <portaudio.h> ..... count = Pa_GetDeviceCount(); but VS2005 say : "libpjproject-i386-Win32-vc8-Debug.lib(pa_win_ds.obj) : error LNK2019: s?mbolo externo __imp__GetDesktopWindow at 0 sin resolver al que se hace referencia en la funci?n _InitOutputBuffer" Please, thank you for help and sorry for A: my bad english B: my poor C skill Gino. >Hi, > >Gino Maffeo wrote: >> I cannot enumerate audio devices on my machine. >> pjmedia_snd_get_dev_count() always return 0. > >I've had a similar problem on an Asus EEE PC 1005P with Ubuntu 9.10.

You can use the Portaudio function Pa_GetDeviceCount to see if the problem is in there. Do other programs using Portaudio (e.g. Audacity) detect your sound cards? > >I fixed it by compiling PJSIP with the PortAudio libraries installed on the system (the version shipped with Ubuntu) instead of the version that ships with PJSIP. See ./configure --help on the --with-external-pa option. NB: this option is currently only available in SVN trunk, not in 1.5.5. > >Regards, > >Bram -------------- next part -------------- An HTML attachment was scrubbed...
