When I set the audio output to silent and turn down the volume to 0 the noise sound changes a little, but continues playing. When I plug in earphones the laptops speakers stop playing it and the sound gets only played through the earphones, that's my current workaround to get rid of the annoying noise. Other sounds like music still playback normally, but the noise is always in the background. I think I've got an Intel HDA sound card build into my laptop (the new audio-settings tool only shows intern audio as it's name). Before the upgrade there was a second Soundcard in the list, but that one didn't work. The laptop is a LG R710. If there are any logs and configuration files I can append to help you please tell me.
