Oh323tut is getting quite old but here are some tips to get and set the Audio Driver and Device Name

Get the drivers PStringArray names = PSoundChannel::GetDriverNames();

Get the devices PString DefaultAudioDriver = names[0]; PStringArray playDevices = PSoundChannel::GetDeviceNames(DefaultAudioDriver,PSoundChannel::Player); PStringArray recDevices = PSoundChannel::GetDeviceNames(DefaultAudioDriver,PSoundChannel::Recorder);

Enumerate the devices for (PINDEX i = 0; i < playDevices.GetSize(); i++) { cout << playDevices[i] << endl; }

To set the driver call these functions PBoolean H323EndPoint::SetSoundChannelPlayDriver(const PString & name) PBoolean H323EndPoint::SetSoundChannelRecordDriver(const PString & name)

To set the device call these functions PBoolean H323EndPoint::SetSoundChannelPlayDevice(const PString & name) PBoolean H323EndPoint::SetSoundChannelRecordDevice(const PString & name)

Hi,

I have downloaded the source code of "h323plus core"(version:1.23.0) and "PTlib"(version:2.10.1) from the link:

http://www.h323plus.org/source/

on my X86 Desktop system running ubuntu 10.04

I have followed the tutorial given at link

http://toncar.cz/openh323/tut/index.html

I am able to compile both the source codes without any problems.

Then I have downloaded and compiled "oh323tut" (version 1.1-1) source code from the link below:

http://toncar.cz/openh323/tut/files.html

I have got simph323 installed on my system using

$ sudo apt-get install simph323

Now when I try to run oh323tut application and simph323 application (in separete terminals) using the commands below:

$ ./oh323tut -f audio.wav -n -u 320 $ simph323 -n -u 321 320@127.0.0.1:1820

I am getting the following problem:

H323> Could not open sound device Default - Check permissions or full duplex capability.

Can anybody please help to  solve the above problem.
