Some codecs (like mine ALC268) just unable to do echo in hardware. For 
some others, with recording from playback mixer, snd_hda just unable to 
configure such echo. Last could probably be fixed by adding some more 
logic to the parser, but I just don't see good reason for this, except 
probably just singing karaoke, which I don't like. :)
