It's not really that there's a battle and audio is losing, it's that browsers still have pretty poor audio support, so there's far less features that can be done on audio than on artwork. We're aware of many of the issues and it's been on our todo list to fix them for a while (lots to do as always).
BTW you can play sounds in the project bar by right-clicking and 'Open'. You can also play random sounds with the 'play (by name)' action, e.g. "mysound" & floor(random(10)).
