ya, for some reason, at first boot when the phone comes up, sometimes the volume will show mute. Just up the volume. Always fixes it for me. Something in the provisioning cab causes it as it doesn't happen when i cook the carrier files in. For my next update these are going to be a few things to expect: MMS settings included in carrier cab so no other cab needs to be installed, volume mute at first boot fixed, upgraded manila, you think the manila has been fast so far in my roms, just wait
