I'm here again. I've just re-flushed shr-testing and I'm back to square
one. Is it just me that have problems with these defaults or it's a
widespread issue ?

I've changed in /etc/frameworkd.conf
ti_calypso_dsp_mode = long-aec+nr

and in /etc/freesmartphone/alsa/default/gsmhandset

4:'Speaker Playback Volume':2:115,115   
---- was 127,127 (this affect the handset speaker) 

then following
http://wiki.openmoko.org/wiki/Neo_Freerunner_audio_subsystem#Alsamixer_channel_controls

I've changed :

5:'Mono Playback Volume':1:105
---- was 110

12:'Mono Sidetone Playback Volume':1:5
---- was 7

48:'Mic2 Capture Volume':1:2
--- was 3

My guess is that the two most important defaults are ti_calypso_dsp_mode
and the control 12 as Al J. pointed out. Can anybody confirm this is a
good solution ? I'm made limited tests, but in the next few days I'll
ask friend about the quality of the sound... It would be great if we can
fix these settings once for all. Few months ago, before reflushing in late
december, I didn't have any problem. I guess we lost good defaults along
the way.

:)
