[Asterisk-Users] SPAM MESSAGE - [Asterisk-Dev] warning message (sound card) - when I run asterisk!!!

[Neo Jia]

All,
   After installing asterisk on Linux, I run "asterisk
-vvvc". But I got the following warning message:

chan_oss.so] => (OSS Console Channel Driver)
May 26 00:37:58 WARNING[-1084845952]: chan_oss.c:980
load_module: XXX I don't work right with non-full
duplex sound cards XXX
  == Registered channel type 'Console' (OSS Console
Channel Driver)
  == Parsing '/etc/asterisk/oss.conf': Found

temporarily unavailable
 [chan_phone.so] => (Linux Telephony API Support)
  == Parsing '/etc/asterisk/phone.conf': Found
  == Registered channel type 'Phone' (Standard Linux
Telephony API Driver)

My sound card information:

Vendor : Intel Corp.
Model  : 82801CA/CAM AC'97 Audio Controller
Module : i810_audio

After running 'dial' command under the asterisk
prompt, I got the following message without any sound.

Is there anyone can give me any hints or help?

Thanks,
Neo
