Hey guys,

This morning I tried to listen to music on my computer. But when I opened the player, I fond that the moving waves strips in the audio controller have disappeared. Usually, if those strips disappear, there should be no sound. But what's strange is that I can hear the sound. I do not know why! In addition, my laptop is newly installed with Win 8 OS.

Pls do me a favor!

Thank you very much!

hi hongmay,

Visit the support website of the manufacturer of your PC or motherboard, search for the Windows 8 audio drivers,
download and install them.

hope this information might helps.
