I've just finished the first year of a four year degree in music but I pretty much spend most of my time programming games

It sounds like you have great potential as an audio programmer.

when I come out of my degree I won't have any qualifications to saying I can actually program apart from the projects I have produced in my free time.

I don't think this is necessarily a big deal. In my experience, good demo projects are worth far more than qualifications when it comes to demonstrating your programming ability. The exception may be working with large companies and recruiters, who may look for qualifications as an easy way to filter a long list of candidates into something more manageable. So apply directly to small and medium sized developers, include your hobbyist experience in your CV, and where possible bring your demos and show them off!
