I have a problem when I try to run ohphone
I get this message

root is calling host 192.168.5.229
Command ? Could not open sound device - Check permissions or full duplex capabi lity.

My gnomemeeting which came with fedora is working just fine audio and video
I am running on fedora3 2.6.9 core
My build options are
PWLIB ./configure --disable-openldap --disable-openssl --disable-sdl --disable-sasl --disable-expat --enable-plugins --enable-alsa
OPENH323 ./configure --enable-rfc2190avcodec=/root/ffmpeg/libavcodec

I solwed the problem

branens@neobee.net

I solved the problem using oss alternative is alsa I didn't use alsa

First I noticed that pwlib didn't build oss plug in there was no sound_oss.o in /root/pwlib/lib/obj_linux_x86_r

My options were for pwlib ./configure --disable-openldap --disable-openssl --disable-sasl --disable-expat --disable-alsa

so I checked the make file in pwlib\plugins And manually altered the file putting ones for oss pwlib and v4l Make file is below

pwlib\plugins makefile

HAS_ALSA = 1

ifeq (1,$(HAS_ALSA))
SUBDIRS += sound_alsa
ifeq (,$(DEFAULT_SOUND))
DEFAULT_SOUND = sound_alsa
endif
endif

HAS_OSS = 1

ifeq (1,$(HAS_OSS))
SUBDIRS += sound_oss
ifeq (,$(DEFAULT_SOUND))
DEFAULT_SOUND = sound_oss
endif
endif

HAS_V4L = 1

ifeq (1,$(HAS_V4L))
SUBDIRS += vidinput_v4l
ifeq (,$(DEFAULT_VIDINPUT))
DEFAULT_VIDINPUT = vidinput_v4l
endif
endif

I bulild pwlib again

Then I made folowing changes in the code ohphone\main.cxx

add this line in the top of main.cxx

#include "/root/pwlib/plugins/sound_oss/sound_oss.h"

and my openaudiochannell looks like this

BOOL MyH323EndPoint::OpenAudioChannel(H323Connection & connection,
BOOL isEncoding,
unsigned bufferSize,
H323AudioCodec & codec)
{

if (isEncoding) {
PSoundChannel* soundChannel = new PSoundChannelOSS("/dev/dsp",isEncoding ? PSoundChannel::Recorder : PSoundChannel::Player,
1, 8000, 16);
codec.AttachChannel(soundChannel);
}

else {
PSoundChannel* soundChannel = new PSoundChannelOSS("/dev/dsp",isEncoding ? PSoundChannel::Recorder : PSoundChannel::Player,
1, 8000, 16);
codec.AttachChannel(soundChannel);
}




codec.SetSilenceDetectionMode(currentCallOptions.noSilenceSuppression ?
H323AudioCodec::NoSilenceDetection :
H323AudioCodec::AdaptiveSilenceDetection);

return TRUE;
}



After this changes sound worked ok

I hope this helps
