The application is set to use a different audio device than
speakers. Some graphics cards support audio over the DisplayPort
connection, so multiple audio devices may be listed in
Device Manager. Make sure the correct device is being
used.
Some applications can select which audio output device is
used. Make sure the application has selected the correct audio
device.
The operating system controls may be set to use a different
audio device as the default output device than what is
expected. Set the operating system to use the correct audio device.
Sound from headphones is not clear or muffled.
Cause Solution
Headphones are plugged into the rear audio output
connector. The rear audio output connector is for powered
audio devices and is not designed for headphone use. Plug the headphones into the headphone connector on the
front of the computer.

the hard disk. You can also try recording the audio file in a
compressed format.
