You may be able to use the "/usr/share/openmoko/scenarios/voip-handset.state" profile. Otherwise, it's a matter of studying the WM8753 diagram as shown on the "Neo1973 Audio Subsystem" wiki page and setting the appropriate mixer controls to route PCM audio to the speaker and to route the mic2 audio into the ADC. Note that the Freerunner has different audio wiring (and a different amplifier chip) than the Neo1973, but I don't think there's a dedicated wiki page for it yet. In addition to xoscope I have been using the 'jaaa' spectrum analyzer from http://www.kokkinizita.net/linuxaudio/ (which includes a sine-wave or noise generator). There's a bitbake recipe for it in the org.openmoko.dev branch of the Openmoko git repository. > 2. a) A bluetooth headset is mentioned as a possible workaround, has > anyone tested this, I've tried but failed to get a Plantronics 220 to work.

GPS, VMWare and question about bluetooth headset
Hi there, First off I just want to say thanks to the guys who figured out the SD card effect on GPS. Tested this and TTFF was 72 seconds while walking to work this morning (there aren't enough hours in the day, so some things need to happen in transit). I only got the physical device yesterday, and was able to setup the USB and get USB networking going in a Ubuntu VMWare Image. This worked well, except for the fact that I lost the USB connection when Windows power saving kicked in, so keep that in mind if you are going to use VMWare to run opkg etc. Note that I haven't tried flashing using this method yet, I want to see that it is stable enough first. I am really determined to use the Freerunner as my phone for everyday use. I believe that this is the only way to make sure that the phone is usable and that application interfaces are practical. At the moment that is a bit tricky because of the echo and interference when making phone calls, but I believe that these issues aren't insurmountable. The reason I got an open phone is because when issues like these creep up I have the option of getting in there and trying to sort it out myself. It is with that in mind that I will be installing XOScope to do some tests of my own. Questions: 1. In ticket 1267 the following statement is made: *"With a few mixer tweaks it is possible to send a 1 kHz PCM tone out through the call speaker"* Can someone ellaborate on what these tweaks are? 2. a) A bluetooth headset is mentioned as a possible workaround, has anyone tested this, b) does it get rid of the echo as well as the interference c) and is there a BT headset that anyone recommends if I am going to test this myself? Rock on developers! J ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
