Portaudio doesn't really work, use ALSA and set the device with PH_FORCE_AUDIO_DEVICE. Search for it in the wiki. Improved audio support will be available with wengophone-2.2 too.

Re: [Wengophone-devel] Linix: portaudio link problems
I posted something on 6/28 that may address this: avcodec_version is in libavcodec.so ( or libavcodec.a ), which comes from the ffmpeg project. I had this problem a few days ago when I was trying out the latest version of ffmpeg with wengo. The problem is prob. one of the following: 1-You're somehow not linking with the libavcodec.a library. Possibly because you have the wrong settings for FFMPEG_OLD_VERSION in $WENGO/DefineWengoOptions.cmake or the wrong settings for FFMPEG_INTERNAL in $WENGO/libs/3rdparty/CMakeLists.txt 2-You're creating shared/static libraries but the linker is looking for the opposite kind. 3-You're using a version of ffmpeg from the ffmpeg site, which has a header ( avcodec.h ) which does not do 'extern "c"'. Because of this the C++ compiler can't find the name, because it is expecting the name to be mangled. -Dan Alec leamas wrote: I'm running into problems with the current head of 2.1 when trying to build with the libportaudio option enabled.

[Wengophone-devel] Linix: portaudio link problems
I'm running into problems with the current head of 2.1 when trying to build with the libportaudio option enabled. The problems are invariably unsatisfied references to the ffmpeg av* libraries. On 32-bit suse the problems disappears if I enable the internal ffmpeg library. If I try to use the external libraries (which are installed) I get link errors in the final link step with the unsatisfied references above. On 64-bit Fedora I get the same link error when trying to use external libraries. Trying to use the internal ffmpeg I get make[2]: *** No rule to make target `.. /libs/3rdparty/ffmpeg/libavcodec/libavcodec.a', needed by `libs/owwebcam/libowwebcam.so'. I am able to build without the portaudioption. However, no sound on Fedora ;-) So I thought I should give libportaudio a chance... Is this known bugs, is it like it's intended to be, or am I just doing something stupid? Any clues out there? --Alec ___ Wengophone-devel mailing list Wengophone-devel@lists.openwengo.com http://dev.openwengo.com/mailman/listinfo/wengophone-devel
