[CLAM] ALSA, AudioIn & dropouts

[David García Garzón]

The dot indicates an xrun. AudioManager and AudioOut, are obsolete, and we are 
not testing them at all, it is possible that we might introduce some 
regression. You should use instead an AudioSource inside a network with a 
PANetworkPlayer. Take a look to this example:

share.upf.edu/wikis/clam/index.php/Constructing_and_playing_a_simple_network

I don't know for sure whether this will solve the xrun problem but it could. 
Anyway it is the way to go. Tell us whether the network approach works, 
please.

David.
