I can also confirm that cracking is gone with new update. It changes firmware of audio components to newer than on Harman/Kardon version. It's first audio update I think for the "normal" version of One M8.
If anyone is planning to root or install custom to try Viper4Android - don't! I tried 2 most popular custom ROMs and also tried various audio mods and enhancements. While you do get plenty of configurable options it's just sounds worse - trust me. One M8 with stock ROM and newest update is as good sounding as it gets. Disabling LPA also doesn't do any good. Be happy with what you get
BTW. I tested cracking with Sony XBA-H3 - on max volume. I'll try other power hungry IEMs to see if there's to crackling on them too.
