That is normal behavior.
The sound in GoToWebinar is always what the computer sees as a microphone. GoTo will not play system sounds, videos, music, sounds coming from PowerPoint, etc. It will share only sounds the computer sees as a microphone input.
The workaround to this is to use the Share Video feature where you upload a video to the GoTo cloud to be part of a particular webinar. During the webinar, you can pay the video at any time. The video will play directly from the GoTo cloud to every computer. One drawback is that the sound will play only on computer speakers, not on the telephone for people who choose to use the phone for the audio part of the webinar. Find this feature in the Dashboard under "Engage Your Attendees," then click the link under "Videos." You can upload up to five videos per webinar.
We are hoping that GoTo will soon add this feature to allow us to play videos on our computer and have the audio sent to all Attendees.
There are some workarounds using the Windows sound panel, third party software, and looping cables from speaker outputs to microphone inputs, or by using extra hardware to send the video and audio from a second computer to the webcam input of the main computer. All of these workarounds have limited success, as GoTo also has a "downward expander" on the audio, which will make any music sound really bad.
We are hoping that GoTo will add a defeat switch to this audio filter that we don't need all the time.
