v5-131 strange buzz noise from notebook speakers when no sound is playing

[stclaus199]

i hear from notebook speakers strange buzz noise. but when i play some kind of sound (for example: a change of volume level in windows mixer - which makes a sound) that noise disappears. but after the sound stops playing the noise is back again.

when i mute sounds (via windows mixer) there is no buzz noise.

when using external speakers i cant recognize this kind of noise and its change when playing any sound.

this issue is not microphone related - i disabled it and that buzz noise remained.



this buzz noise is so annoying. please help anyone

thank you!

best regards
stclaus

uninstalling built-in realtek device drivers made a trick. after restart it started to work properly - without any further driver installation. i assume w8 installed some own drivers..
