[QtMoko] Freerunner making a squealing noise
Hey all, Has anyone else ever experienced a loud squealing or shrieking noise on their Freerunner that begins some amount seconds (varies) after starting or receiving a phone call? The noise rapidly gets louder once it starts and within about a second is much louder than the voice. Both parties can hear the noise and it makes communication very difficult. I first noticed it on the 18th which was a few days after I updated from QTEI to QTMoko (FSO variant 20090707). This Freerunner has not been buzz fixed, but this is not a buzzing issue. The noise sounds like no kind of RF interference or feedback that I have ever heard - the pitch is not fixed and the closest thing I can think of to compare it to is the wind whistling through some trees, but much louder and quite a bit harsher. -I -- http://darkstarshout.blogspot.com/ -- On the day *I* go to work for Microsoft, faint oinking sounds will be heard from far overhead, the moon will not merely turn blue but develop polkadots, and hell will freeze over so solid the brimstone will go superconductive. -- Eric S. Raymond, 2005 -- Please avoid sending me Word or PowerPoint attachments.

I get a similar sound when using the Freerunner near an external mic or speaker system.

Re: [QtMoko] Freerunner making a squealing noise
I had this problem with QtEI - I think the issue was related to the speaker phone mode being turned on incorrectly and generating some kind of feedback. Since I didn't use the speakerphone mode, My solution was to just copy the alsa state file for handset use overtop of the speakerphone alsa file.
