I am using Snow Leopard and I have recently purchased Magic Jack and I notice that every time I plug the USB device in it changes my sound settings (I want to keep the settings to internal) is there any way to fix/prevent this??
Based on this link, which relates to Windows, you should look at System Preferences > Sound > Output to see what is selected as your default. Also look at Sound Effects to make sure it says "Play alerts and sound effects through: Internal Speakers"
I do have my internal speakers set as my default configuration. But the problem is still there. When I plug my USB device the sound settings are changed to the USB device and don't stay as "Internal Speakers"
Yeah that's what I have had to do until now, every time I connect the USB device it switches so I have to go and manually change to the internal speakers in Sound Settings.
