Alsa tool on arch: Echo-cenalletion dosen't work

(E)ivil · 2017-08-15 08:24:23

So, let's start from the begining... I want to use my microphone in some application like skype/discord, but i i've noticed, that audio from my device doing annoying noise... So i decide to find something to solve this problem. Okay... Arch-wiki.. Alsa Troubleshooting... Great!

There's first problem - after save default.pa and resart pulseaudio, sound in Arch is muted and can't find any of sound deveices (like speakers) i have.

Second

[some@some ~] arecord -f cd -d 10 test-mic.wav
ALSA lib pcm_dsnoop.c:638:(snd_pcm_dsnoop_open) unable to open slave
arecord: main:807: audio open error: No such file or directory

What exactly did you change? Post the files you adjusted. You likely loaded pulse's echo cancel module incorrectly. What are the outputs of

sudo fuser -v /dev/snd/*
pulseaudio -vvv
#If pulse is running
pacmd list-sources
pacmd list-source-outputs

while recording.

Edit: It should be source-outputs sorry

w8...

There is another problem:
after paste this to default.pa

### Enable Echo/Noise-Cancelation
load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=1" source_name=echoCancel_source sink_name=echoCancel_sink
set-default-source echoCancel_source
set-default-sink echoCancel_sink

pulseaudio can't be started.

[some@some ~]$ pulseaudio -k
[some@some ~]$ pulseaudio --start
[some@some ~]$ pulseaudio --start
[some@some ~]$ pulseaudio -k
E: [pulseaudio] main.c: Destruction of service failed: There is no such process
[some@some ~]$ pulseaudio --start
E: [pulseaudio] main.c:  Service launch failed.

oh and after delate this code everthings working good besides recording.

and now outputs after restart without this sentence...

i see...
Alsa dosen't see my front panel with 2x usb; 1xjack for headphones and 1Xjack for headphones.

I've got 2 systems on my computer - arch + win10
On win that's working.

Okay.. now front panel works but... smae problem with aecord and there is static noise.. again.. same problem like before.
