First good experiences, except for the microphone

[hartrumpf]

Hi all.

I bought a Neo Freerunner some days ago, installed
the latest SHR without any real problems
(after flashing, I had to boot twice instead of one boot;
that was ok for me).
The Freerunner is much more usable than I expected;
thanks to the community!

Currently, I know only one annoyance:
the microphone does not work well (hardware or software, I have no idea).
On the receiver side, there is some noise (up to 20 or 30% of the voice signal,
I would guess)
that makes it hard to understand the person with the Freerunner.
(The other direction is fine, i.e. good audio output
on the Freerunner side.)
Any known solutions, yet?

Greetings
Sven

Do you have an A6?  If yes see buzz fix in the wiki

Yes, but I am still hoping that I do not belong to the 2% unlucky ones,
let's see what others think ...

Thanks, I found:

http://wiki.openmoko.org/wiki/GSM_buzz

It contains the following link for explanation, but this
link does not work anymore:

http://lists.openmoko.org/nabble.html#nabble-td1509627|a1509627

Can anybody fix this link, please?

Ciao
Sven

It depends what kind of noise you have.

If it's a constant buzzing you might consider having a look at the hardware
buzzfix just like rakshat mentioned.

If you experience a rustling noise, check your gsmhandset.state file ( in
/usr/share/shr/scenarii/ ). The "Mono playback volume" may be overdriven a
little bit. The easiest way to adjust it is to log in into the phone using
ssh, open alsamixer, start a call and find out the best values. After that,
make them persistent in the gsmhandset.state file. Be aware that the ranges
might differ in alsamixer (0 - 100) and the file (0 - 127). You will have to
adjust them properly.

Hope this helps.
Michael

No, it was more like noise from a very crowded place.

I have decreased this value by 20 -
now the noise has disappeared (almost completely).

Yes, thanks!
