[Solved] Static in Mic after taking tips from wiki

Using a Hyperx cloud core on asrock b350 mobo. Others sound find to me through my headset but they report static from my mic is audible to them. I've added

default-sample-rate = 48000
resample-method = src-sinc-best-quality

to the bottom of

/etc/pulse/daemon.conf

and added

use_ucm=0 tsched=0

to the end of

load-module module-udev-detect

in

/etc/pulse/default.pa

Even with

load-module module-remap-source source_name=record_mono master=alsa_input.pci-0000_28_00.3.analog-stereo master_channel_map=front-left channel_map=monoset-default-source record_mono

from $ pacmd list-sources | grep 'name:.*input'
	name: <alsa_input.pci-0000_28_00.3.analog-stereo>

at the end of default.conf I can hear the static in the playback.

This is using discord by the way, is it just a side effect of discord on linux. I see numerous other topics with the same issue but they just say the above changes fixed it where its still there for anyone I talk to.

Re: [Solved] Static in Mic after taking tips from wiki

Have you tried without doing these changes? Those are emergency options for fixing broken drivers and are not generally necessary nor recommended. src-sinc-best-quality doesn't make sense either way (even if you indeed were to fix something with e.g. tsched=0), as that resampler has been removed from the pulse package. use speex-float-5 or something.  FWIW post

pacmd list-sources
pacmd list-source-outputs

during crackling playback.

I can hear static along with my voice with the default pulseaudio setup. The only change that I see I should keep is setting the rate to the correct value:

$ arecord --list-devices
**** List of CAPTURE Hardware Devices ****
card 0: Generic [HD-Audio Generic], device 0: ALC1220 Analog [ALC1220 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Generic [HD-Audio Generic], device 2: ALC1220 Alt Analog [ALC1220 Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

$ arecord -f dat -r 60000 -D hw:0,2 -d 5 test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 60000 Hz, Stereo
Warning: rate is not accurate (requested = 60000Hz, got = 48000Hz)
         please, try the plug plugin

Re: [Solved] Static in Mic after taking tips from wiki

That test completely bypasses pulse, so if you already get crackling with that, your error is either on the driver or the hardware level. can you post

amixer -c0
systool -vm snd-hda-intel

Re: [Solved] Static in Mic after taking tips from wiki

Ah whoops would have to be

systool -vm snd_hda_intel

.  Any way, decrease the boost and up the actual volume instead:

amixer -c0  set 'Rear Mic Boost',0 0
amixer -c0  set 'Rear Mic',0 50%,50% unmute #Not sure what the exact relation between these 2 is, but still bring them down to a more sensible value
amixer -c0  set 'Capture',0 50%,50%

Re: [Solved] Static in Mic after taking tips from wiki

Tested after changing amixer values, playback was still my voice with static around it. Enabling echo-canceling seems to be a solution however. Adding

/etc/pulse/default.pa:

load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=1" source_name=HyperX_echocancel sink_name=HyperX_echocancel source_properties=device.description=HyperX_echocancel 
set-default-source HyperX_echocancel_source
set-default-sink HyperX_echocancel_sink

Seems to provide to clear-er recording I was looking for. Again thank you for the help and feedback.

fyi the "source_properties=" isn't needed it just makes the sink easier to read in pavucontrol.
