Local sound may be fixed by alsamixer setup resp choosing right 
version/editing of handset.state file in /usr/share/openmoko/scenarios.
Far end noise seems somewhat dependent on FR's local GSM service provider and 
actual basestation, more than on alsamixer settings. We are still 
investigating this.
The issue doesn't seem to depend on sw-image largely.
