[Asterisk-Dev] CMI 8738 problems with getting Asterisk to usethe card

[Wade Weppler]

I found the ALSA drivers for the 8738 will enable Full Duplex.  If you're
using RedHat, you can use the RPMs from www.freshrpms.net for easy
installation.  Just follow the ALSA doc's for installing specific drivers.
