Buzzing Noise when Laptop connected to TV with HDMI

by shikaka88 / November 20, 2013 11:21 PM PST

Hi, I have an Acer Aspire 5741 connected to Samsung TV (LE22B450C8W) by a hdmi cable, and whenever it is connected there is an annoying high pitched buzzing noise coming from the TVs Speakers.

The sound isnt there when my TV is connected to anything else. I have tried a few different HDMI cables- all have no effect. I have tried unplugging the laptop from the mains so it is running on battery- no effect.

The noise is unrelated to what level the laptops volume is set at, and is unrelated to what volume the TVs speakers are set at, except if you hit mute- that silences it. Also plugging headphones into the TV stops it.

Does anyone know what it is and more imortantly how I get it to go away,
Many Thanks,
