The Media Source API might give you the control you need:
http://dvcs.w3.org/hg/html-media/raw-file/tip/media-source/media-source.html
This isn't widely implemented yet, but I think it will be.

However, we should not add new APIs to the Web platform to work around
crippled implementations of existing APIs in certain browsers. That makes
no sense at all. If some browser implements <audio> elements in a way that
creates a problem for you, you need to petition that vendor to change their
implementation.

Gentiles lord it over them, and their high officials exercise authority
over them. Not so with you. Instead, whoever wants to become great among
you must be your servant, and whoever wants to be first must be your
slave — just
as the Son of Man did not come to be served, but to serve, and to give his
life as a ransom for many.” [Matthew 20:25-28]
