I installed the ROM on the Y300 as well and have - like others - problems with the audio over a paired bluetooth headset.
** Please note that I am using a Y300 and not the G510 device. Several users wrote already that the G510 works fine with Bluetooth **
I narrowed down the problem to the following:
- Pairing of the BT headset works without problems
- I hear sound notifications (incoming call, dialing sounds) over the headset
- On the call screen, you can select the output device. This is set to Headset but does not work, it uses the normal phone
- Changing the setting to phone and back to headset does not change anything, as it looks like the "output to headset" config is overwritten by the "phone" setting.
Please note that apps like BTmono do not work in any way. I tried them all ;-)
*** Workaround ***: There is a way to make it work though, which is kind of annoying though. During the call, you can go to the bluetooth settings and select your paired headset. It should show the "phone" profile with a checkbox. If you *disable* it and *enable* it again during the call, the audio is directly transferred to the headset and everything is working perfectly.
Do you think there may be any way to fix this behavior?
