[Freeswitch-users] no audio from portaudio in conference

I have audio playing into the MIC (capture) on my sound card. The device is "/dev/dsp" I know there is audio being played into the sound card because when I run: sox -t ossdsp -w -s /dev/dsp ./tmp.wav and listen to tmp.wav, I hear the audio. When I call a conference using "/dev/dsp" no audio is being played from the capture into the conference. If I use freeswitch-1.06, portaudio seems to work. I'd like to use the latest FS version for many reasons. Any ideas what has changed in mod_portaudio? Maybe something broke? It doesn't seem like many people use this module and may not be maintained or bugs may not be submitted for it. I'll do any debugging necessary and any advice would be appreciated. Thanks.
