Comment 29 for bug 1318360

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.
