Rustling noise on phonecalls

[Michael Zanetti]

Hi everyone,

Lately my Buzz-fixed Freerunner began to make a rustling noise during 
phonecalls. I cannot hear it on my side but I constantly get complains from 
the persons on the other end. Some test calls here confirmed that the noise is 
really here and its really loud too.

It is not the well known buzz. It sounds more like if a small animal were 
sitting in the mic and moving around during the phonecalls. Or if I would 
constantly rustle with a peace of paper against the mic.

I have already opened it and checked if the buzz fix is there how it should be 
but everything seems to be ok. I've also cleaned out the dust from the mic 
hole but the rustling is still here...

Judging from the time when other people complains started I think it happened 
after an upgrade of my SHR unstable. But I'm not really sure. It could also be 
that the GSM firmware upgrade to moko-11 somehow triggered this behaviour as 
I've upgraded it about 2 weeks before the complains started.

This happens now with SHR as well as with om2009-testing5.

I am using the gsmhandset.state file suggested by Jörg.

Anyone has an idea what could be the cause of this. In this current state my 
freerunner is absolutely useless as a phone.

Thank you all,
Michael
