Thank you for the answer. I would never have bothered the list without going through the source :) The 'silencelevel' and silencetimeout settings have _no_ effect. I should have mentioned that in my posting.
It also still leaves the question, that I am able to set the codec <microphone [..] > <method name="_makeDevice"><![CDATA[ var dev = super._makeDevice(); [..] dev.codec = 'Speex'; [..] ]]> </method> /microphone> ... but all other settings (i.e. dev.setGain, dev.setRate) will compile but not render the Flash. I might be overlooking something, so any push is appreciated. Michaela
