Hey guys,
Wanted to share my project with you. I recently added a Raspberry Pi2 and RuneAudio to my Apple iPod HiFi.
I'm really happy with the result! It works and sounds great!
The only issue I had with it was getting Rune Audio working on a Raspberry Pi2. However after trying a build someone from the forums posted, it now works great!
You can check it out on my blog:
