aRts will compose the audio data it gets, e.g. decode compressed data like OGG 
vorbis and then write this to the sound driver depending on its configuration

If ALSA is the sound system which aRts is configured to use then yes.

Hmm, does your ALSA setup allow concurrent access to the sound device? e.g. 
having a card that allows to be accessed by more than one application or an 
ALSA level sound mixer

Check by running to ALSA programs other than aRts
