Turning down the mic volume doesn't really help with the GSM induced buzz. it makes it quieter for the person on the other end, but it makes you quieter too, so you are just as difficult to understand. A separate problem that is often reported as 'buzz' is clipping distortion caused by incorrect volume settings for the mic. This can occur on phones with or without the buzz fix. The two sorts of 'buzz' sound different though. The buzz induced by the GSM signal happens whether or not you are speaking, as it would if you were standing next to something buzzing loudly. The buzz from clipping distortion happens only when there is sound, usually when you are speaking but possibly when the mic picks up the echo of the other person speaking. _______________________________________________ Shr-User mailing list [email protected] http://lists.shr-project.org/mailman/listinfo/shr-user
