That's true, but it should be possible to configure alsa mixer settings in such a way that the GSM audio is routed both to the speaker and to the ADC converter of the soundcard. It shouldn't be too hard, I guess you just need to study the mixer settings a bit: http://wiki.openmoko.org/wiki/Neo_1973_audio_subsystem http://people.openmoko.org/joerg/ALSA/doc/WM8753_control_diag.pdf Greets Richard > > Cheers, > Mike. > > _______________________________________________ > Openmoko community mailing list > [email protected] > http://lists.openmoko.org/mailman/listinfo/community _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
