Badly phrased from me, I guess a better way to say it would be "scratchbox can 
use whatever audio system is present on the host computer".

The version of esound that is shipped with Maemo SDK seems to be like on N770 
defaulting to /dev/dsptask. So it didn't work for me, since the host is 
running ALSA with OSS-emulation (see above :-), and (DSP 
Gateway's?) /dev/dsptaskX directories do not exist there. So I took the 
esound 0.2.35 sources from 
http://ftp.gnome.org/pub/GNOME/sources/esound/0.2/. After installing the 
esound stuff to the SDK from these, esd starts and works.

If I now succesfully compile and test an audio application with this new 
version of esound under Maemo arm-target, what is the likelihood the app 
would also work on the N770? Am I doing something fundamentally wrong here?
