Low volume while playing on-line broadcasts or archives may be caused by a setting on the sound mixer of the computer.
Right-click the speaker icon at the bottom right of the screen and select "Open Volume Control" to open the sound mixer.
To adjust volume on Windows XP:
For Windows XP (or similar), please make sure that the mute boxes
are not checked and the volume control sliders labeled "Wave" and
"Master Volume" are up -- then press OK.
To adjust volume on Windows Vista:
For Windows Vista (or similar), sliding the volume control on the "Windows
Media Player" application should adjust the mixer volume. If not, please make
sure that the mute box is not checked and the volume control sliders labeled
"Windows Media Player" and "Speakers" are up -- then close the dialog box.
(If a volume button does not appear, press the Start button and type
"sndvol" in the Program Search box. Click on the "sndvol" link that appears
to open the volume mixer.)
Please also check the volume slider on the Windows Media Player itself.
Version 11 of the player may require clicking on the volume button to access
the slider.
At times, it may reset itself to about 50% when the player starts.
