I tried updating the modem firmware as explained at https://lists.launchpad.net/ubuntu-phone/msg08514.html, but no apparent change. I, too, previously had the more recent radio image M9615A- CEFWMAZM-2.0.1701.07 until I flashed the m9615a-cefwmazm-2.0.1700.98 image. I'd be willing to play around with alsa-mixer settings, but I don't know how to do it on the phone at this point.

Several people can confirm that there is a noticable difference in terms of sound/microphone quality between Android and UT in phone calls. With UT, my voice gets distorted to an extent that person at the other end have real difficulties to hear what I am saying, while with Android call quality is much better with no distortion. I have had a suspicion for a long time that this might be a software and not a hardware issue. After trying Android and Ubuntu on the same hardware I believe this suspicion is proved correct. This issue has persisted in all the builds I have tried since at least the beginning of the year, but probably longer. I am now at r17 of Utopic.
