Audio quality on Lollipop topic

Hi

Has anybody noticed degraded audio quality with any of the lollipop roms?

I have a Bluetooth car stereo with a subwoofer and on KitKat (ARHD) it sounded sweet but seems to sound awful on Lollipop.

I've tried ARHD and I'm not on Leedroid and the H/K audio mod has helped but it still sounds poor.

Thanks.
