Is your mic creating a buzz, issue resolved

[Udayan]

I had a very feeble buzz noise coming up when i record via mic. I emailed Notion Ink support and i got a reply immediately, Yet to test if this fixes the issue. Will try this out. However i thought it might be useful to put it here so that others will find it useful.

"Dear Sir,

Doesnt work, I already tried!

That screeching/buzzing noise is the dimmer on your screen. Any such update they send will never actually remove it. They're just trying to include some more noise cancellation software in hopes that your mic will stop picking it up. Hasn't worked for anyone on the conclave yet either.

[Udayan]

It did not work for me as well.

Is this persistent across all ROMs ?

What may be related, the mic in my observations is extremely hot - as if the gain control is maxed out. The mic picks up movement on the surface of the device, making speech-to-text entry very difficult if you are holding the adam in your hands or moving it around.

I am guessing they have yet to optimize the best gain/boost settings for the mic under it's current placement. Are there any apps out there that allow mic settings to be viewed, if not adjusted?

[Udayan]

Oh that is quite informative. Let us hope NI sees this and fixes this. The gain coul certainky be a possibilty.

Good for you! I have just updated my Adam from EdenX to HoneyComb! Not sure how to remove ClockworkMod which probably is creating few issues with FCs.
