I'm at about 3 to 4 seconds delay for hearing.  This is after a reboot.

1. enter phone call mode
04-10 10:42:22.937: V/AudioPolicyManagerBase(89): setPhoneState() state 2

2. set audio path to DEVICE_OUT_EARPIECE
04-10 10:42:22.947: V/AudioPolicyManagerBase(89): setOutputDevice() routing=1

But I didn't see audio hardware to configure audio driver. 
Need partner take look first.

Loop Sam.Hua

I think you have updated the modem and nvitem, it may cause mozilla incoming call issue.
You should check it and uplift new pac to FTP.

This issue is fixed on spreadtrum bugzilla, but mozilla should update modem.

Following the STR from Comment 0, confirmed in the latest Tarako build that sound can be heard immediately after being connected.
