Chrome is right now , the most recommended browser for html5 games , and probably the answer to your question ... Also , I've been using Chrome for quite a while and nothing happened , so nothing to be scared off !
@Whiteclaws: Chrome is OK but not "THE" solution. FF is more than capable, and OGG format comes from free source softwares like FireFox.
@Astrosus: Post your capx and the sound you're using so we can try and have a ear by ourselves. Make sure all your drivers are up to date as well as your version of FireFox (17.0.1 at the time of writing).Kyatric2012-12-30 00:22:04
