[SOLVED] Static noise on my microphone ( pulseaudio )

A few days ago i've installed arch again, for test how much i learned since a year ago.
The problem is, i setup all fine except pulseaudio. Before i reinstall arch, i solved this issue with this article:

Microphone distorted due to automatic adjustment

But now, i have the same issue and the previous article doesnt solve that.
So i tried also the next articles:
Static noise in microphone recording
Another possible cause

The only modification that improve the situation was the Noise cancellation, but the static noise still there.
I guess i miss some dependencies, but i'm not sure.

pulseaudio version:       14.2

What i installed:
* pulseaudio
* pavucontrol
* alsa-utils
* alsa-firmware

daemon.conf

default-sample-format = float32le
default-sample-rate = 48000
alternate-sample-rate = 44100

default-sample-channels = 2
;enable-lfe-remixing = no
remixing-produce-lfe = no
remixing-consume-lfe = yes

resample-method = soxr-vhq
avoid-resampling = yes

default.pa

.fail

### Automatically augment property information from .desktop files
### stored in /usr/share/application
load-module module-augment-properties

### Should be after module-*-restore but before module-*-detect
load-module module-switch-on-port-available

### Load audio drivers statically
### (it's probably better to not load these drivers manually, but instead
### use module-udev-detect -- see below -- for doing this automatically)

### Automatically load driver modules depending on the hardware available
.ifexists module-udev-detect.so
load-module module-udev-detect
.else
### Use the static hardware detection module (for systems that lack udev support)

### Load several protocols
load-module module-dbus-protocol

### Load the RTP receiver module (also configured via paprefs, see above)
#load-module module-rtp-recv

### Load additional modules from GSettings. This can be configured with the paprefs tool.
### Please keep in mind that the modules configured by paprefs might conflict with manually

### Make some devices default
#set-default-sink output
#set-default-source input


### My custom configs

Re: [SOLVED] Static noise on my microphone ( pulseaudio )

Potentially an issue with snd_hda_intel power saving that got enabled by default. Make a /etc/modprobe.d/disablePowerSave.conf

options snd_hda_intel power_save=0

and reboot to check that.

Otherwise during an affected recording session post the outputs of

pacmd list-cards
pacmd list-sources
pacmd list-source-outputs

Re: [SOLVED] Static noise on my microphone ( pulseaudio )

Thanks for the reply c:
I've read your same answer in other similar issues and i tried it but not works, i forgot to say it, my bad.
Fortunately, or sadly i was able to solve the problem reinstalling arch again.

I think the problem was pulseaudio-qt package, because this time (and the first time also) i installed pulseaudio (not qt package) and the solution that i mentioned before works (This solution)

Regards
