FR audio subsystem: gsmhandset ... files
Hello, Is there still someone out here in the Openmoko list who could explain and/or discuss my questions concerning the FR audio subsystem? See also http://wiki.openmoko.org/wiki/Neo1973_audio_subsystem http://hnet.endofinternet.net/elektro/Freerunner/ALSA/sound_setting.html I'd like to have a general understanding and in detail how the gsmhandset (...) files are used in the FR, for example in the SHR distribution.

Before you answer or make a call you do: alsactl -f gsmheadset.state restore and after hanging up do: alsactl -f stereoout.state restore I don't think there's any magic involved there...

There you will find for the GTA02: [alsa_control_speaker] speaker = Headphone Playback Volume microphone = Mono Playback Volume microphone_mute = Mono Mixer Sidetone Playback Switch This are the three controls which libphone-ui will adjust for speaker/microphone volume and muting the microphone (you will also find them with alsamixer). regards, Simon -- Simon Busch - http://mm.gravedo.de/blog/ ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
