Um. Try playing an mp3 using mplayer, make sure you install Johnx's a2dp package and enable a2dp. See what output mplayer produces, it will either spit out some info about the stream type (if the DSP is working) or it will say something along the lines of "falling back to sw method" (if the DSP fails). Alternatively, look at the output of "dmesg" just after trying to use the DSP task, and it will say something about having loaded the task, or about not having been able to do so iirc. I don't have my headphones here so I can't check I'm afraid, and I won't be able to check till Sunday. Sorry, Simon
