[Asterisk-Users] Asterisk ALSA module not working

[Moshe Yudkowsky]

Asterisk doesn't work with the latest CVS of ALSA (2003-06-24) . The 
module chan_alsa.so won't load even if the oss module, chan_oss.so, 
isn't loaded. There are no error messages.

I've been chasing ALSA/Asterisk/client problems in one form or another 
for some time now. In previous versions of Asterisk and ALSA -- i.e., 
last week -- I could load either chan_oss.so or chan_alsa.so; as of this 
morning, only chan_oss.so will load.

The symptoms are very straightforward: If chan_alsa.so loads, no 
subsequent module loads. An outward sign is that "show dialplan" will 
have just a few items and not the entire dialplan because pbx_config.so 
doesn't load, and important functions like "stop now" do not exist at 
the console.

There are no error messages, and just the ordinary debug messages. I 
haven't had any success deciphering the problem -- I'm still figuring 
out its extend and ramping up on new sections of Asterisk code.

I am using the latest (2003-06-24) CVS of asterisk.

Question: Is anyone using Asterisk's chan_alsa.so and ALSA version 0.9.4 
from a later CVS? I like to know if it's some problem with my local 
configuration or a bug I haven't found.

Related question: Are OSS and ALSA mutually incompatible? I would think 
so, but there's nothing in the documentation. If they should *not* be 
loaded simultaneously, I will submit a few lines to patch modules.conf.
