[Freeswitch-users] No audio after upgrade to F17

Well this is odd, after I installed F17, I don't get audio to or from the pstn line (via a spa3102 ata) once the call is answered. I do get ring tones, and Fs generated voice messages, and can leave or retrieve vm. I've tried a couple approaches so. When I installed F17, I copied the FS installation directly Booting back to F14, every this works as expected, so it's not the spa3102 or config files. Thinking there might be a incompatibility issues, I recompiled FS under F17, no change in operational behavior. Ideas where else to look ?
