[Freeswitch-users] Problem in getting digits value in Playback application

Wed Sep 24 19:58:43 MSD 2014

The port audio error seems to indicate that there isn't any kind of sound
card or other audio device. I don't see how installing sound files could
possibly fix that. Port audio requires some kind of hardware - sound card,
USB headset, etc. - in order to function properly.
