I am glad to say that with linphone-3.2.99.7 I can now register with
ekiga.net correctly and I can also exchange video by calling
address@hidden

Audio transmission and reception also works correctly if I plug in an
external microphone. However, linphone-3.2.99 will not pick up my
netbook's internal microphone. All other programs requiring capture
input will detect when an external microphone is present or not,
including linphone-3.2.1, but linphone-3.2.99 will not do this.  I
notice also that the first few lines of the debug window after starting
the program have this:

The fourth line says "Could not attach mixer to card: Invalid argument".
This may or may not have something to do with it, but as I say an
external microphone works fine, including the capture volume, as does
the received audio.

I am using the ALSA HDA Intel interface (ie neither OSS nor pulseaudio).

Thanks for all your work on this.
