Audio problem with CMA Desktop 5.1

I'm getting no audio when I enter a conference with CMA Desktop, only when I enter the conference.

 

When I go to Properties -> Audio -> Test Audio Devices, the audio works fine.

 

I tried to reinstall CMA, the headphone, nothing works.

 

I'm using: CMA Desktop 5.1, Logitech USB Headset, Windows 7 32Bits, Note Dell Latitude E5400.

 

It was working fine.

 

Its not working with the note audio too.

Re: Audio problem with CMA Desktop 5.1

Hi!

 

 

Please note that withing Windows 7, when plugging in a USB headset, it "overrides" any other sound device (for example speakers connected with a mini-PL cable).

 

Please confirm that the default audio device is indeed matching between Windows 7 and the Polycom CMA Desktop.

To check this, please refer to Microsoft's Website:

 

http://windows.microsoft.com/en-US/windows/help/no-sound-in-windows

 

In addition, you can also try the Fix-it tool from Microsoft:

 

http://windows.microsoft.com/en-US/windows-vista/Tips-for-fixing-common-sound-problems

 

As for the CMA Desktop, please navigate to:

 

Preferences->Audio->Choose Audio Output Device (it could be it set to "Auto", however you can change and select the output source manually to match your headset).

 

 

Hope this helps!

Re: Audio problem with CMA Desktop 5.1

Hi Daniel,

 

Thanks a lot for your help, but my problem it happens ONLY when I'm in a call through CMA Desktop.

Even the soud test in the CMA Desktop works perfect.

I tried using skype to test and everything is working fine too!

Thats the wierd part, everything works fine until the call is conected in the CMA Desktop.....

 

Any clue??

Re: Audio problem with CMA Desktop 5.1

Did you try connecting without the aid of the MCU to a regular video endpoint directly?

 

Also -

 

  • Are you trying to establish an encrypted call?
  • Are there any packets lost (Audio) when connecting?
  • Is there any jitter (Audio) when connecting?

 

 

Thanks!

Re: Audio problem with CMA Desktop 5.1

Yes, I did and still the same...

 

I don't know how to see if it is encrypted or not.

No, the network is fine, no packets lost.

No, no jittering too.

The tests that I'm doing is over a Lan not a Wan...

 

Tks for the attention
