RE: 5510: Audio from websites not working when external monitor is also hooked up. (But Skype sound still working)
Hello. What might be happening is after you connect to the external display, the audio switches to HDMI audio. To get the audio to emit from the laptop's speakers again, go to the Windows Sounds dialog and make Speakers the default playback device (right click). You might have to do this every time you connect an HDMI cable.
