Question about Altec Lansing BXR1221 2 Speakers
I am having a problem today with my altec lansing bx1221 speakers. I cannot control the volume using the volume control located on my speaker. Currently I have to use the volume control in windows 7. It was working fine until yesterday, when I accidentally unplugged them from the back of my computer. I have made sure both plugs are connected completely and are in the right slots. I have also double checked that it is plugged into the outlet completely. any ideas on getting the control to work again?

its best way to check the problem whether hardware is not working or any driver related in computer,
1) hook up any working head phone in your pc's head phone jack (generally of green color plug)
2) checkout that both LH and RH side speakers working!!
after that we can guess.

I work for a charity that had one of these donated today and as I was looking for a new sub for my cinema system I purchased it. I have no other speakers with it and no way of switching or varying the volume. I opened up the back of the sub and slid the board partly out exposing the PCB.
You'll see 3 solder connections behind the scre in an "L" configuration. One of them is common, one volume and one power on. As I don't need volume, I'm happy with it being on full as my cinema system will vary the input, I joined all 3 together giving power on and full volume. It is working great now.
For you guys with volume controls, I would suggest shorting out the two rightmost pins in the "L" and I recon this will power it up and try varying your volume control. I recon it'll work just great.

Unfortunately the subwoofer supplies the power to the amp on the speakers, Once again I have the solution,
These speakers are factory molded so that the only way to open them is to break the factory seal
this can be done by sharply rapping the seam at the bottom of the speaker with a heavy screwdriver handle or something similar.
Now you need to supply power to the amp...If you do not have the subwoofer you will need a 4.5volt power supply, after removing the board from the casing find the red white and black wires connecting
the orange plug wire to it, Personally I removed the entire cord from the unit, shough you can splice in at this point if you desire.
Connect the white lead to your posative on your power supply by either splicing or soldering, connect the ground to the heat sink using the screw that is already there holding the chip to the sink. reassemble the speaker.....super glue... and you are now in business.

The solution is actually quite simple, due to a design flaw. Altec lansing designed a rather cheap mini din plug-in which can either be replaced or repaired depending on your skill and patience level. Your ground contact is fine BUT the positive contact is not making connection due to the fact that the plastic housing has broken away and pulled the contact with it. This can be super glued back into place or just replaced with a new mono minidin plug-in.
