[asterisk-dev] Using dmix plugin with chan_alsa.so

[Nick Lewis]

I vaguely remember having a pig of a time getting alsa mixing to work.
Spent much time figging around with various alsa config files such as
asoundrc etc. In the end I think I upgraded alsa and used the config
files from the upgrade without modification. The alsa interfaces named
"default" then seemed to include dmix and dsnoop implicitly (they could
be avoided by using alsa interface "hw:0,0" instead). I made no changes
to chan_alsa.c (not for this anyway). Looking at a machine on which it
is working I see that there is /lib/libasound.so.2.0.0
/lib/libasound.so.2. I regret that my memory of this is very flakey but
it may be worth giving an alsa upgrade a try.
