AApparently there is an order of operation to using adapters, stereo headphones, and the 8100.
If you do:
1. Start the 8100 media player (wait for sound)
2. Plug in the adapter, to the 8100, nothing connected to the adapter yet (wait for audio to mute)
3. Plug stereo headphones (or stereo speakers) into adapter.
You get: Sound on one side. (or at least I did).
If you do:

2. Plug stereo headphones (or stereo speakers) into adapter.
3. Plug adapter in to 8100.
You get: Sound in both speakers (or at least I did).
Can anyone else replicate this scenereo?

I can :>.
I talked to our tech support department and the problem lies with the way the 8100 detects audio input. Here is a direct quote:
"This was a known issue when we did the test on the adapter samples, even on our BB8100 adapters. For this customer, he will get a L/R channel reversed sound anyway.
Basically, the 8100 has a headphone detection system. Once you plug in an adapter or any audio pins into the Blackberry, it will start detecting whether the R channel and the GND is connected. If the R channel and the GND is connected or the R channel is empty, the 8100 thinks a mono headset is plugged in. Therefore, all the music will only play on the one side which is the left side.
In other words, when the 8100 detects a resistance, the 8100 will think a stereo headset is plugged in. Then the music will be played in stereo."
For right now: Any headset
MUST be plugged into an adaptor
BEFORE it is plugged into the 8100 itself. Again, let me emphasize that this is an 8100 production issue and not a product related one. We are also in the process (and will have ready very shortly) just a simple 2.5mm>3.5mm without any microphone capablilities.
Hopefully, that clarifies things. Our folks are working on developments that may help to deal with this in a more elegant way. Please let me know if you have any other questions.
