Why can't I hear sound when I web chat?

Episode 1030 (1:33:36)

Joan from Garden Grove, CA

Joan has a new computer running Windows 8.1, but the sound doesn't work when she's doing webcasts. Leo says to go into the sound control panel and see if 5.1 surround sound is on. He advises changing it to mono or just stereo.

The chatroom says that changing to 2.1 sound will fix it. Leo also thinks that it may be a surround sound encoding issue. If it's flash, the chatroom says to disable hardware acceleration in Flash settings. She also may need to reset her sound settings in Google+.
