xv6800 no sound on phone

[Gurny]

Just cooked up a nice ROM (based on 3.35.NO2.5060, radio 3.27.00) using the BuildOS tool. Unlocked my xv6800 with Olipro-2.40 The only issue I have is that after a build and deploy (and hard resets), I never get any sound. Particularly the phone during a call doesn't have any sound; I can't hear the other person and the other person can't hear anything I'm saying either. (and yes I checked the volume - it had to be said). I'll also try to play a wav file or just try to test a notification sound and nothing comes through.

I've tried multiple roms (No2Chem's Titan 5060 and 5054's) and get the same sound issue. However, when I flash an older rom (eg. dcd_titan_kitchen_2.3.2) I get the sound back. Is there some setting that I can look at?

Thanks,

Gurny
