I noticed that there are two similar options in the "Sound" (Soundcard Configuration window->playback tab in the context menu) window in Windows 7.

What is the difference between these two options?

  • "Set as Default Communications Device"
  • "Set as Default Device"

There is a blog about it here.

  • Set as default device - All programs will have their audio played through this device (unless otherwise configured)

  • Set as default communications device - All calls/video call audio will be played through this device (unless otherwise configured)

    This makes sense concerning playback devices. For recording devices and microphones, I do not understand the distinction. – Ronnie Overby Jan 06 '21 at 15:40
  • You could choose to use a high-quality microphone for conferencing, gaming, etc. but leave your laptop's microphone as the default for basic voice commands. – Neman Jul 12 '23 at 17:16
