Dell 5559 i5 6200u with AMD m350 audio crash(audio cracking sound) when power source is changed usually when power shifts to battery. the problem often occurs when watching online videos, like from youtube or Facebook. the sound is choped and terrible noise came with audio from Laptop speakers. But no sound issue when using a plug in device like headphones. or external speakers.
only solution is to restart that application.
Search for sound goto the properties of the speaker now to the advanced tab and select the bitrate '24 bit,48000Hz....or you could just uninstall the audio driver....hope this helps
Select the bitrate of 24 bit,48000hz or u could just uninstall the audio driver
