Hello,
I am lead technician for a university library, and we have just recently upgraded our phones in our building to CX300s and CX600s Polycom VoIP phones.
First I would like to say that I have posted this issue on the Polycom Community site and they suggested that I post this in the Microsoft Endpoint forum. I could not find that section, and since Lync is apart of office now, I posted it here.
We have a recurring issue with the CX300 phone with several of our faculty. The phone is taking control of the audio on the computer and it will not relinquish it. We tried using speakers, headphones of all platforms, (USB, 3 1/4 jack,
etc...), reinstalling the sound driver, looking at the settings in BIOS, but the sound always is comes from the phone. There were instances where we could get headphones to work, and sometimes a sound bar / traditional desktop speakers, but there is
one faculty member where everything that we have tried has failed. All of these users are on Dell Optiplex 760s or higher, and we are using the onboard sound (front and back ports in some cases). They are all connecting the phones through the
Lync client. All of these computers are also running a Windows 7 Service Pack 1 build. Any insight to this would be much appreciated.
