Thanks for letting us know!

I am using multipoint server 2011

Thanks for the quick reply!

Do you have multiple units of the DC-125 ( to make it easy to isolate down a hardware problem? If not, is there a Windows desktop machine around, on which we could test the DC-125, confirm audio is working, then bring back to WMS 2011 to configure?

Thanks for your patience!

I have four other DC-125 units on the same machine and they all have working sound output. I have also tried using working headphones and speakers on the DC-125 but still it does not have any sound.

Hi Thad,

Thanks for your quick reply!

If you swap a working DC-125 with the suspect unit (exchanging headphones and USB connection), and the problem follows the suspect unit, that would confirm it.

In that case, please just email us at with your Amazon order # and we’ll get a replacement out to you right away.

Thanks for your patience!
