Alsa settings for qtopia on freerunner

[Christoph Siegenthaler]

Hi

The default alsa settings in qtopia 4.3.3 pretty much suck - at least on  
the freerunner. I was able to get rid of the ear-busting (caught me on  
surprise) echo noise by disabling sidetone in the gsmhandset.state file.  
What are other good settings? I don't really want to spend a lot of time  
calling myself to tweak my FR2

Best regards, Christoph

P.S.: Any news on when to expect qtopia 4.4?
