Thanks, Joerg - I hadn't noticed that comment. Hmm - would it be possible to add a note at the top of the file itself indicating this? I found a post by you in the community list indicating that this was the 'real' state file to use, and so have been using it. I didn't think to check the comments on the associated issue. And frankly, my audio quality with it is better than with any of the other state files I've tried - much less buzz. Is it possible that the changes in the -a7 file reduce the impact of the buzz? I'm probably going to keep using it until I get the buzz fix operation performed. Warren On Tue, Jun 9, 2009 at 9:14 AM, Joerg Reisenweber jo...@openmoko.orgwrote: Am Mo 8.

Maybe this is something different than the Buzz Issue, but it improves sounds for the other party a lot. I've experienced that on some settings the background noise of my environment (=cars / computer fan / air conditioning / ...) is amplified a lot when I'm silent and the person I'm talking to can hear it. It isn't easy to recognice what's the source of the noise but I'd say there's some tunign to do to make this work.

After reading that less than 5% of the owners are hit in practice by the Buzz Issue, I was pretty surprised to be one of them. But now it seems the noise is not due to the Buzz Issue? reducing mic gain and/or mic volume might cause some of the many sound improvement circuits involved in carriers' exchange (here: half duplex echo cancellation, kind of a two-way noise gate) to cut out buzz during periods of no voice transmitted. Nevertheless the S/N ratio *during talking* (S=your voice, N=buzz) can NOT be changed by alsa settings any way whatsoever. So this change of control.5 may improve some of the subjective audio sensation for far end, only if you got slight buzz that becomes unnoticeable during actual voice. Severe buzz rendering voice illegible can NOT be cured this way, not even a little bit. btw you can get same result (without lowering volume of your voice for far end, and without relying on carrier's/far-end's EC meassures) by setting AT%N noise gate value of Calypso to a level that effectively stops buzz during periods of no voice (aka silence) Official recommendation is: If you got Buzz issue, try to get bigC-buzzfix. cheers jOERG signature.asc Description: This is a digitally signed message part. ___ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support

Hi Joerg, I certainly don't mean to downplay the research you did - I was just trying to explain the experiences I've had. When I set control.5 to about 85 I no longer heard a buzz when I called myself on a phone - A few people complained that I sounded a bit muffled, so I reset it to the 101 (same as gsmhandset-a7.state), and since then it seems pretty good - my wife has complained once about some intermittent minor buzz, but I've had a number of phone conversations where people said I sounded fine. I've still seen varying opinions on these mailing lists ranging from 'only 5% of people need the buzz fix' to 'everyone with an A5 or A6 needs the buzz fix'. Is the official line that everyone with an A5 or A6 would benefit from the buzz fix?

I've still seen varying opinions on these mailing lists ranging from 'only 5% of people need the buzz fix' to 'everyone with an A5 or A6 needs the buzz fix'. they're not really varying -- it's like learning to swim: if you are absolutely sure, you'll never get into deep water, there's no need to spend time learning how to swim. but if you're unsure, you better do it. it's the same with the buzz fix: if you don't experience it and if you are absolutely sure, the location and conditions your fr works under will never change, no need to fix. technically, though, the buzz is there and you might experience it when you expect it the least. so, if you got the opportunity to get the fix applied, use it -- better safe than sorry. ___ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support
