Windows 7: Stereo Mix giving awful echos - tried everything...

Stereo Mix giving awful echos - tried everything...

Hi everyone.

Here is my predicament: I am using a music production program called Cubase to play live piano music over Skype. I am using 'CamStudio' At the same time to capture the live screen and audio. I also talk into the mic.

To do this I need to use the stereo mix option, but it unfortunately has a crippling destructive feedback echo!!

Does anyone have any suggestions? I have struggled with this issue for a few months now and am tired of it. Should I just do a complete re-install of all my sound programs?

I use ASIO4ALL with the Cubase I don't know if that helps...

Some other things that may help...

  • I can record the video fine on cam studio but it is not recording the audio, to do that I need to put my stereo mix sound up, but that causes echos. At a volume level of about 7 I can get the audio to record on cam studio but it is too low to be useful, any higher and the feedback starts.
  • My default playback device is a C-Media PCI Audio Device.
  • Under recording I have "Microphone: 2 audio device" set as my default communications device and "Sterio Mix: C-Medial Audio device" set as my "Default Device".
  • Other sounds like youtube and system sounds work fine with stereo mix all the way down.
Thanks for listening!

I have a recording studio (using Sonar X3).

With a DAW program (Cubase) and the other program both working at the same time almost anything is possible. ASIO4ALL can also cause problems. I realize many use it if there is no ASIO driver for a device, but there is a 50% chance of ASIO4ALL causing problems.

You are asking the sound card to do double duty at the same time. You should consider an external recording interface unit (that is OS compatible and has ASIO drivers) as a starter.

Hey, thanks for the reply! I solved the problem, it involved unchecking 'listen to this device'. I realize that I can not use cubase and youtube at the same time now because ASIO4ALL limits the number of applications you can run with sound to a grand total of O-N-E.

As we say in France, Cest la vie!
