Noise appears after playing music with iTunes for a while

[zitaofang]

I'm using ALC887(model on specification) on GA-Z170-HD3P, and it's shown in DPCIManager as ALC888B whose Codec ID is 0x10EC0887. When I'm playing music with iTunes on 10.11 El Capitan, it works good for about 2 minutes, then the noise appears. I can solve it by switching to another port in preference then switch back or pausing it for 3 seconds, but that will happen again after another 2 minutes. The speaker is connected to the green rear port, and my layout ID is 1. More information will be provided if needed. Thank you!

I do not own a Skylake system, no testing to date. For those using Skylake/AppleHDA solutions, no reports of "noise". No suggestions are this time.

I have the same problem on ALC887 (Asus B85M-K)

8 series is very different than 100 series. Describe your noise problem in detail.

OK. The driver works good in the first 2 minutes when playing music with iTunes, then the speaker begin to make some static noises. I can pause it or switch to another outputs for a few seconds to solve it temporary. But I found that the static noise wouldn't appear when playing music or watching video on websites like Youtube and SoundCloud just now. Maybe iTunes uses some special APIs.

I will test the audio with other apps and report the result later.

Previous reply was for ifamed (trying to hijack your issue). It is not possible for the motherboard/codec to make static. Case grounding problems, speaker cable, speakers, etc. are potential causes.

@zitaofang Hi, I have the same MB as you (GA-Z170-HD3P), I had noise ALL the time, I use VoodooHDA, I just went to settings -> VoodooHDA and set Input Gain to 0 (min) - no noise anymore. But to keep it permanent even after reboot - copy /System/Library/Extensions/VoodooHDA.kext somewhere then right click "show content" and set Info.plist the iGain param to 0, after that install that kext with e.g. "Kext Wizard"

This is not the VoodooHDA project. I had the same issue when I used VoodooHDA (noise all the time), thus I changed it to this kext, which only produces noise in iTunes after playing music for 1min. So I encourage you to replace your kext and see if there is the same problem. Just download it in "releases" and replace the one in your S/L/E.
