Z60t and Motorola HT820 Headphones

[mudtoe]

Hi folks:

I've got a Z60t with bluetooth (E7U model), and am trying to use a pair of Motorola HT-820 headphones with it, and have had only limited success. It seems like they work only with the regular Bluetooth Audio device (from the Sounds and Audio devices control panel applet), not the High Quality Bluetooth Audio device. When I try to use the High Quality device (by disabling the regular bluetooth audio device in device manager), I get just little spits and fits of sound. However, the little bit of sound I did get seemed better than the sound when I was using the regular bluetooth audio device. The regular one seems to be only mono, as nothing happened when I played with the balance controls for the device. I've also noticed that some audio still comes out of the laptop's speakers, not the headset, even though it's working. Obviously I'm a bit confused as to how this is supposed to work, as I doubt you are supposed to disable one audio device in device manager to use another, but I couldn't find anything else that controlled it. I understand that I need the A2DP bluetooth profile for high quality sound, but I couldn't find a way to see what profiles were installed, and I wasn't absolutely certain it was needed if you have BT 2.0 installed (I've applied all the patches the update manager had available for my model). If anyone has gotten these headphones to work with the Z60t I'd be interested in any pointers you could give me on what I need to do.

Thanks,

I just bought a set for my T42 and had them up and running in minutes at high quality with the BlueSoleil bluetooth stack.

The trial version makes you reload the program after 5MB of transfer, which is plenty to let you test it and use it for a bit to make sure you want it. The cost is 10.99 euros.

You must have the Advanced Audio Distribution Profile, or A2DP, regardless of your BT hardware version. Profiles and BT versions are completely indepenent of each other as far as I've been able to figure out. There could be a profile that requires a certain BT version as a minimum, but I haven't heard of one yet. Your BT stack probably doesn't have A2DP, which would explain why you can't get the full hi-fi stereo sound to work.

Did you somehow get the HT820s working on the internal bluetooth card? Or do you have to use a dongle?

I haven't used that headset with the HQA via Bluetooth; but I have done the same with my Motorola RAZR and it works fine. If I recall correctly, you don't, and shouldn't, have to disable the base Bluetooth audio for it to work. Are you using the WIDCOMM stack that came with the Thinkpad?

Me? I'm using the internal card. It's the IBM Bluetooth III card that came with the machine.
