i have the same problem with a tdk a33 speaker (great sound) i'm guessing it's a problem with support for the protocol which there are many of and you can only know what you are using by pulling logs from the phone... not much you can do unless it's a problem with the phones bt stack. if the speaker has it's own volume control it might not support remote volume control. but if the speaker is meant to be controlled from the phone then it might be possible that changing the bt stack or driver for the bt chip in the rom/kernel would solve the issue. this would require rooting and flashing though.

can you control the volume with other devices? i haven't really messed with mine enough to know which device is the problem...

DANG! I just ordered a tdk a33 and didn't realize the phone wouldn't control the volume.
Is there any software that will work to do the volume control?

The phones framework supports BT volume control but it seem like the BT stack doesn't have complete support for the particular protocol some of these devices use...

When I try to adjust the volume the bar shows on the screen and it move and the speaker icon is substituted with a BT icon... A custom ROM might work but I can't recommend any as I haven't tried them yet... I will work on a solution and post detail here when I know more... My fathers old galaxy s 2 works perfectly with the a33 and I will check with my infuse that runs cyanogenmod.

after some googleing there seems to be bugs in the new bt stack... supposedly from somone testing 4.4.1 they fixed it.. but who knows. i don't even know how to become a 4.4.1 tester...

in the meantime i think any fix will need root.
