Clicking/Poping + White noise Sound problem.

Rexikon · 2017-04-23 15:07:29

For first i tried all from https://wiki.archlinux.org/index.php/Pu … leshooting and i tried some methods described on this forum.
Nothing work.

I would use my integrated sound card.

My hardware:

Processor: Intel(R) Core(TM) i7-7700K CPU 
Motherboard: PRIME Z270-A

Recorded example of my sound problem: https://www.youtube.com/watch?v=CP4JJNf … e=youtu.be

When i have pulseaudio process terminated the white noise still exist.

Any know how to fix it?

Is this a new motherboard? Do you know if everything can actually work well, like, do you know that things are fine with Windows or with Debian or something?

My motherboard (GA-Z77X-D3H) has this kind of noise in its audio output and it's really just how the hardware is. I can hear different noise with CPU load, mouse movements, graphics card doing something, etc. I need to muffle the noise by making sure I keep the volume high in the OS and instead reduce volume externally. This all works out because without an external volume control, my motherboard already produces loud enough output for headphones at something like 10% volume setting. I can then set volume to 50% and use external hardware to reduce volume which also suppresses the noise enough to not be able to hear it anymore.

EDIT:

Another thing I remember I've seen on an ASRock H110M-ITX/ac motherboard is this:

On that PC I use speakers that are connected to the motherboard with normal 3.5mm for analog audio and get their power through a USB cable. If I connect the speakers to a USB port of the motherboard, there's terrible noise and it changes depending on what the CPU does. If I instead connect the speakers to a normal power outlet through a power supply, there's no noise. There's something "dirty" about the power supplied by the motherboard and that produces the noise in the speakers.

Yes this is new motherboard.

The same problem occurs for me.

Recorded what? PCM? Mic? Line In?
The common issue is that some unwanted input is not muted (check capture devices in alsamixer w/o pulseaudio) - the unplugged jack then catches some EM load and produces white noise, that's "normal".

I recorded sound from my speakers using phone, there is no other captures devices in alsamixer :c

Pops: https://wiki.archlinux.org/index.php/Ad … g_playback

Hiss: mute all playback controls with names like "mic" and "line", they feed analog input signals to output which may be the source of noise. Capture controls only matter when recording from analog inputs to software.

Ah, sorry - I thought this was a problem when recording (eg. with a microphone), not a permanent annoyance from your speakers.

=> See what mich41 said about hiss - you can also (likely) mute all analog playback.
If you need the devices, look out for a "mic boost" toggle and in doubt dump

for ((i=0;i<4;++i)); do amixer -c $i; done

Is that the entire output? (Looks like only one valid card and one error, but you suggested to have 4 cards and the loop attempred 4 cards, so at least there should be 3 errors)

Anyway, did you notice that your microphone is wide open (looks like the BEHRINGER device)?
