[Linphone-users] Mediastreamer ring_test messages

[Bob Burchsted]

10 March 2006

I am running on a (HP) Compaq nc8000 laptop with Red Hat Fedora Core 4,
Linux
version 2.6.15. I am running Linphone 1.2.0. I am trying to understand
the mediastreamer interface. When I run mediastreamer/ring_test, I get
the following messages

-----

I had to copy share/rings/oldphone.wav to share/ring.wav to satisfy
the ring_test program input file. I also changed the card number to
'0' from '1' in the call to 'snd_card_manager_get_card', to get
/dev/dsp. (Leaving it as '1' generated no sound). Aurally, it is noisy
and the ringing sound is not correct.

If I set the card number to '2', I get the following messages

-----------

This is also noisy.


Where can I start to look at what is causing the 'Must catchup...'
messages and the alsa-card-write messages? 

Thanks.
