Angry [Q] CM and CM based rom bluetooth sound quality

All CM based roms from around 4.1.2 to 4.4.2 all seem to have the same folly. On certain bluetooth devices the playback of audio is slowed down sounding lower pitched, and it is choppy with skips.

Going from a clean CM, to trying a more rounded Liquid Smooth there is no difference.

Flashing to a stock ROM clears this issue.

Now, the problem is that 4.4.2 is much much much much much more pleasant to utilize from the eye candy, to it's features (most importantly the dialer), and customizable settings. Let's face it, 4.3 is crap in comparison.

Is there hope that the CM source that the other roms use will be fixed to eliminate this bug? Can the old blueZ stack be baked into the roms? There is thought that the old stack offered better sound quality.
