I am still having this problem. If volume is greater than 80 % there is significant crackling / popping.
This is most noticeable on voice. For example watching TV on Hulu or Netflix. The problem occurs using Xbox video with local stored videos. I have updated everything. If I turn off enhanced audio this fixes the problem but the audio is so quite I can't listen to Hulu , Netflix or music. Has anyone found a fix for this yet. I have had this since Oct 2013 and with each update this problem does not get any better. So many updated have been very rocky! I am starting to believe Microsoft cut corners regarding the speakers. This is a very disappointing issues especially when you need to have the volume great than 80%. This plus other issues has turned me off to future surface purchases.
