It is not good idea to break existing applications even if they 
are closed... And there are some open source meego/nemo 
pulseaudio modules which using cmt speech (but audio quality is 
worse).

Anyway what is /dev/cmt_speech doing? If it exports gsm voice 
call data, should not it have alsa snd interface?

V4L2 interface is not for video/camera/capture/tv cards?
