If you are going to do this repeatedly you probably want to edit /usr/share/openmoko/scenarios/gsmhandset.state or make a copy of this file with a suitable name (gsmstereoout.state is assumed as a new state file name below) and modify it with your preferred text editor. The state file will show alsa controls with their range of allowable values, and a descriptive name. You are looking for controls 74, 75 and 1 respectively, assuming you are using a gta02. For 74 and 75 you want to change 'value false' to 'value true', and for 1 change both value.0 and value.1 from 0 to something much higher, perhaps starting at full volume (255) and reducing it if this is too loud. You can use the state file during the call using alsactl: asactl -f /usr/share/openmoko/scenarios/gsmstereoout.state restore Or you can make the changes individually using alsamixer. This can be a little confusing as there are a _lot_ of controls, and the descriptons are shown slightly differently to those in the .state file. When you have settings you like you could save them using alsactl: asactl -f /usr/share/openmoko/scenarios/gsmstereoout.state store Note that in either case a call state transition will cause a new state file to be loaded, so you need to load and/or save your preferred state during the call. _______________________________________________ devel mailing list devel@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/devel
