Port Audio, sound level, and http access to svn ?

[Philippe Torrelli]

Hi Mikael,

What you tell me confuses me, my point is that:

The portaudiodevice.cxx in trunk/libminisip/source/soundcard initializes 
inId and outId in the constructor from the same passed parameter 'Device'
...
Then PortAudioDevice::openRecord .. passes inId as the device to
Pa_OpenStream, 
And PortAudioDevice::openPlayback passes outId as the device to
pa_OpenStream...

Either the code I've compile dis not the right code to build the portaudio
plugin, or I've misunderstood something...

As I've no means now to check the latest versions, all this is probably
irrelevant actually.

Philippe

It's not that old, it contains the gui improvements of audio device 
settings, committed in r2632.
