Answer 1

I am on a Sony Viao VGC-RA826G running Windows XP with a
Realtek sound card. Couldn’t hear Flash audio or event
sounds.
Followed lots of threads, tried lots of fixes... None of them
helped. Here is what my problem turned out to be: Flash
doesn’t play out the Rear or Center/Woofer jacks.
Unfortunately, mistaken information from the sound card convinces
you (in two ways) to use the wrong speaker output: 1) In "Control
Panel-Sound and Audio Devices-Properties-Audio-Sound Playback" the
only option I have available to select is "Realtek Audio Rear
Output", and 2) The "Realtek Sound Manager-Speaker Configuration"
in control panel has the "Front" output of the back panel
mislabeled as "Line Out".
After moving my computer, I had reconnected it with the
speakers in the "Rear Output" jack. That configuration works fine
for wave audio, windows media, quicktime, etc., but not for Flash
or event sounds (which I didn't realize for a long time because I
had event sounds off and I hadn’t tried any flash). Finally
fixed it by moving my speakers to the "Front" speaker output (on
the BACK of the machine, but for the FRONT speakers of a surround
sound system – Flash doesn’t play out of the rear
speaker hjack).
So if you can’t hear Flash audio, check this first:
Plug the speakers in where they belong - the output marked "Front"
on the rear of the machine. Which, by the way, is color coded
correctly on the Viao Hardware. However, the Realtek mistakes can
really convince you that your speaker cable belongs in the "Rear"
output.
