Increase Bluetooth Microphone Volume
There are many posts and topics about increasing the bluetooth mic volume. As many as there are suggestions, there are also unanswered questions.
It has taken me many many days to experiment with different tweaks in my attempt to increase the microphone volume of my bluetooth headset (it was really soft and sounded very "distant").
Finally I found a solution that works for me.
Many sites and forums I came across sugggest changing values in "RECEIVE_UPLINK_VOLUME", "EARPHONE_UPLINK_VOLUME", "SPEAKER_UPLINK_VOLUME", "HEADSET_UPLINK_VOLUME" to "CC" and adding new entries like "MicVolume" in "AudioGateway" if it doesnt exist and even changing the bluetooth headset channel from "2" to something higher.
It may have worked for some but none of them worked for me. There seems to be much confusion about which controls what. After many tries, I decided to set all values back to the original (I did keep a record of what I changed) and give it one last go and now I am plenty glad I did cos now my bluetooth mic volume is just about as loud as speaking into the device directly.
This is the ONE and ONLY value I changed;
HKLM\Software\HTC\AUDIOGAIN\HEADSET_UPLINK_VOLUME = 10 (DWORD hexadecimal).
(original is "0A". The volume seems to be limited at this level but its good enough for me. I think the "limiter" is preventing it from going any higher)
Things I did...
Changed - HKLM\Software\HTC\AUDIOGAIN\RECEIVE_UPLINK_VOLUME = CC (now reverted back to its original = 00)
Changed - HKLM\Software\HTC\AUDIOGAIN\EARPHONE_UPLINK_VOLUME = CC (now reverted back to its original = 19)
Changed - HKLM\Software\HTC\AUDIOGAIN\SPEAKER_UPLINK_VOLUME = CC (now reverted back to its original = 10)
Changed - HKLM\Software\HTC\AUDIOGAIN\HEADSET_UPLINK_VOLUME = 10 (Keeping only this setting)
Added - HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\AudioGateway\MicVolume (now deleted)
Changed - HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\AudioGateway\capability = 74 (now reverted back to its original "37")
Hope this helps anyone who has been trying to bump up the mic volume. Good luck!
