[Asterisk-Dev] Alsa driver doesn't initialize

[Adnan Shah]

I have just installed the Alsa drivers
for my 2.4.18-14 kernel. I have configured
the sound card ok with alsaconf and tested
with the aplay , works fine. But when I run
asterisk it says..
-------------------------------
[chan_alsa.so] => (ALSA Console Channel Driver)
Apr 20 18:28:34 ERROR[8192]: chan_alsa.c:339 alsa_card_init:
snd_pcm_open failed: No such device or address

Apr 20 18:28:34 ERROR[8192]: chan_alsa.c:474 soundcard_init: Problem
opening alsa I/O devices

  == No sound card detected -- console channel will be unavailable

  == Turn off ALSA support by adding 'noload=chan_alsa.so' in
/etc/asterisk/modules.conf

------------------------------
any ideas ?
