Freerunner audio channels

I think you're all missing the point.

David's initial post is a breath of fresh air into a long debated but  
(AFAIK) non-resolved issue.

I deeply welcome his investigation into this subject, and support his  
questions (which I also would like to see answered).

Although the issue of low playback volume is rather well controlled in  
our FRs, the issue of low recording volume for GSM transmission  
remains - with callers still complaining and going "what? I didn't  
hear you..." now and then, especially in (even slightly) noisy  

The whole "audio settings for GSM" issue is _not_ cut and dried, in my  
view. I still have to go into frameworkd.conf every time I flash the  
phone and set the DSP to "long-aec" to avoid echo and sporadic audio  
clipping, as well as raising the volume in playback and mic in  
gsmhandset.state... and I'm still not satisfied with audio quality.

So, can someone please humor David and me and explain this sidetone  
channel business?
