Thanks! With these tweaks to my current settings, I've successfully for the first time received a confirmation that the receiver of my call didn't hear an echo of her own voice. However, I did tweak "Mono Sidetone Playback Volume" from 7 to 4, since in my own testings with two phones I heard quite a lot of buzz still. That lessened it, and the receiver seemed to hear my well enough anyway. My paranoid / not-knowing-what-I-do procedure is to: 1. change /usr/share/openmoko/scenarios/gsmhandset.state 2. alsactl -f /usr/share/openmoko/scenarios/gsmhandset.state restore 3. alsactl -f /etc/asound.state store 4. reboot I now added a link to your post at http://wiki.openmoko.org/wiki/Freerunner_Hardware_Issues#Poor_Audio_Quality since this is the first time I really achieved some good results. -Timo _______________________________________________ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support
