I still can't reproduce this, but see the following. Liens begginng with
'#' in the following trace are comments I have added now and not part of
the trace. Also note that this shifted lines of other messages down a
bit.

Also note that orkadio is not installed on the system. In order to avoid
the install cycle, I have:

  oreka$ ls -l plugins/ orkaudio/orkaudio
  -rwxr-xr-x 1 tzafrir tzafrir 542058 2009-09-23 13:37 orkaudio/orkaudio
  plugins/:
  lrwxrwxrwx 1 tzafrir tzafrir 63 2009-09-23 12:17 libgenerator.so -> ../orkaudio/audiocaptureplugins/generator/.libs/libgenerator.so
  lrwxrwxrwx 1 tzafrir tzafrir 49 2009-09-23 12:17 librtpmixer.so -> ../orkaudio/filters/rtpmixer/.libs/librtpmixer.so
  lrwxrwxrwx 1 tzafrir tzafrir 53 2009-09-23 12:17 libvoip.so -> ../orkaudio/audiocaptureplugins/voip/.libs/libvoip.so

I also moved /usr/lib/orkaudio/plugins out of the way to make sure it is
not used.

My config file:

$ sed -e 's/<!--.*-->//' -e '/^[ \t]*$/d' /etc/orkaudio/config.xml  
<config>
        <AudioOutputPath>/var/log/orkaudio/audio</AudioOutputPath>
        <CapturePlugin>libvoip.so</CapturePlugin>
        <CapturePluginPath>/home/tzafrir/Proj/Asterisk/Oreka/oreka/plugins</CapturePluginPath>
        <StorageAudioFormat>gsm</StorageAudioFormat>
        <DeleteNativeFile>yes</DeleteNativeFile>
        <TrackerHostname>localhost</TrackerHostname>
        <TrackerTcpPort>8080</TrackerTcpPort>
        <CapturePortFilters>LiveMonitoring</CapturePortFilters>
        <TapeProcessors>BatchProcessing, Reporting</TapeProcessors>
        <BatchProcessingEnhancePriority>true</BatchProcessingEnhancePriority>   
        <VoIpPlugin>
                <Devices>eth0</Devices>
                <DahdiIntercept>yes</DahdiIntercept>
        </VoIpPlugin>
</config>

This is basically the default (linux) config file, with the following
differences:

1. CapturePluginPath set to some non-standard value. The value
originally set in the file: '/usr/lib', which is quite non-useful.

2. The value for 'Devices' under 'VoIpPlugin' is explicitly set to
'eth0'. In my case the default value (when it was not set) was "the last
network adapter, which happens to be 'tun0' and not very useful.

As you can see, the voip plugin is loaded from
CapturePluginProxy::Singleton()->Initialize() and loaded from the right
path. A bit later on, LoadPlugins() fails to find the plugins directory
I set and tries to use the hardwired default.
