PPCGeeks - View Single Post - Bluetooth headset volume low unless I plug in my wired headphones first!?!?

I have done tons of research and testing and I am still coming up empty.

I would like to ask a favor, I need someone who has a Bluetooth headset and a stock wired stereo headset.
First install acbToggleBT, this program allows you to open a connection between your headset and your phone. You can skip this step if you already have a toggle program.

Next, play an .mp3 using windows media player or your favorite player.
Leave the stereo wired headset unplugged and run acbToggleBT, this will connect your phone to your headset. You should hear music through your Bluetooth headset. Make a mental note of the sound quality and volume. Run acbToggleBT again to turn off the bluetooth connection. Plug in your wired headset so you hear the music. Now run acbToggleBT agian.

Is the sound quality much better? Is the volume twice as good?

I have been playing with the AudioPara.csv file but the settings don't seam to help. I found the Speakerphone uses the settings in rows:

A12,CE_PLAYBACK_HANDSFREE
F26,CE_PLAYBACK_HANDSFREE
I found the HeadPhones use the setting in the rows:
A17,CE_PLAYBACK_RESET
F25,CE_PLAYBACK_HEADSET

I also figured out Column 4 affects the volume. I tried coping row F25 into F26 thinking that the bluetooth was using the Headphone settings when the headset is plugged in. I also copied the rows into the bluetooth row and it didn't make any difference.

I have one of those little mini usb to 2.5mm stereo adapters. If I plug the adapter in before I activate my bluetooth is sounds great.

I have come to the conclusion that I need an application or program that can enable the headset profile before toggling the bluetooth connection. Effectively making the mini usb trick unnecessary.

One final though, I am using a plantronics 510. Maybe its the difference between a stereo connection and a mono connection. Maybe plugging in the stereo adapter fools the bluetooth to think it should connect in stereo. Is there a trick to make the phone think the bluetooth headset is a stereo device?
