I have certainly already thought about that. I very much want to ditch the BC127 at this point, but I also don't want to have to roll my own audio support circuitry. That's one of the reasons I went with that Sparkfun board was because it had all the audio stuff built in. It's hard to find anything else with the audio part built in. If you find something, definitely let me know.

In case the problem is the sparkfun board itself and not the BC127 chip, there's this but it's 250 Euros and no guarantee it'll fix the issues.

Like the new pic, by the way.
