I set Option to 2 but same problem, the volume would only work through the beo 4, and not on the circular rim on the beo 2.
As suggested, plugging in the head phone socket "released" the wheel and did indeed adjust the volume from the rim, but no sound came from the speakers (Power Link out on the socket box) once headphone plugged in. Pulling out the powerlink cable from the socket box did not restore bc2 volume control either.
I should say that the powerlink cable (from the socket box to the amp) was made up for me by a third party -- just connecting the left right and ground channels, so perhaps this is the issue? I did notice extra pin ports on the powerlink socket.
Any help/advice most appreciated. Apologies for the late responses.
And, Thanks elephant -- I'm glad you figured out the avatar. I'll try those famous 2001 lines on my Mac.
