No output of "Monitor of Null Ouput" #27

Closed Krulvis closed 3 years ago

Krulvis commented 4 years ago

I've been using this module for a while now and it has always worked perfectly. Since I updated arch yesterday, however, the output of "Monitor of Null Output" remains 0. It is visible in the PulseAudio GUI and I can set it as fallback. But the audio level simply remains 0.

These are the settings files that I use:

.include /etc/pulse/default.pa

load-module module-null-sink sink_name=mic_denoised_out
load-module module-ladspa-sink sink_name=mic_raw_in sink_master=mic_denoised_out label=noise_suppressor_stereo plugin=/opt/ladspa/librnnoise_ladspa.so control=50
load-module module-loopback source=alsa_input.pci-0000_00_1f.3.analog-stereo sink=mic_raw_in channels=2 latency_msec=1

set-default-source mic_denoised_out.monitor

default.pa.txt

I recompiled librnnoise_ladspa.so after I noticed it didn't work anymore (after system update) but to no avail. I checked pacmd list-sources and the mic is still named accordingly: name: <alsa_input.pci-0000_00_1f.3.analog-stereo>

I added the latency_msec=1 configuration already before the arch update that broke it since I originally had a long delay.

After I updated arch and noticed it broke I tried the following steps without any success:

What pulseaudio version do you have?

I have 13.0-3 and I don't see it being newer in https://www.archlinux.org/packages/extra/x86_64/pulseaudio/ (however it is flagged out-of-date).

Maybe pulseaudio logs could tell something:

sudo killall pulseaudio && pulseaudio --start -vvvvvv --log-meta=true --log-time=true
Krulvis commented 4 years ago

I also have pulseaudio 13.0-3. Now I am extremely confused :P. I'm currently in a meeting and can't be messing with my sound too much but I'll check with logs in a couple hours. Thanks for the quick response!

Running the command you provided returns the following:

(   0.000|   0.000) D: [pulseaudio][../pulseaudio/src/pulsecore/conf-parser.c:184 pa_config_parse()] Parsing configuration file '/etc/pulse/client.conf'

(   0.003|   0.003) I: [pulseaudio][../pulseaudio/src/daemon/main.c:801 main()] Daemon startup successful.

Doesn't seem like there is something going wrong? I have absolutely no idea how to debug this issue...

werman commented 4 years ago

Ah, the final piece is:

journalctl -b /usr/bin/pulseaudio

That's how you get logs.

Seems like the minimum latency is too low but that fixes itself. I have no clue what the bluez5 NoSuchUnit error is

EDIT: Seems to be related to bluetooth; not the issue at hand. EDIT: If I smack my mic really hard I can see a tiny slither of output coming from "Monitor of Null Output": image

werman commented 4 years ago

I see nothing wrong in logs. Then most likely something wrong in configuration in pavucontrol...

Looking carefully at volumes and enabled status in pavucontrol might help. Or looking at pacmd list-sources.

Puselaudio configuration is a bit weird.

Krulvis commented 4 years ago

When I boost both my mic and "Monitor of Null Output" in pavucontrol to max cap I seem to get some output but the quality is definitely worse and lower quality than before the update. Can't figure anything else out atm, default.pa seems to be fine.

werman commented 4 years ago

I don't know what could gone wrong with your configuration, you could post the output of 

pacmd list-sources
pacmd list-sinks  
pacmd dump

Maybe something would be visible there...

Krulvis commented 4 years ago

I have honestly no idea what happened, I didn't change any settings but this morning it all worked fine again. It might have been a problem with my microphone al tough I wouldn't be able to tell you what the exact problem was...

Krulvis commented 3 years ago

I have to re-open this issue. I simply have no idea what the cause is and I have tried many things but I simply get no output from the noise supressed sink (monitor of null output). First I had to boost my mic really loud to get output but now that doesn't even work anymore. If I use the mic directly in Discord for example people can heard me but there's clearly noise coming with my voice.

This is my default.pa:

.include /etc/pulse/default.pa

load-module module-null-sink sink_name=mic_denoised_out rate=48000
load-module module-ladspa-sink sink_name=mic_raw_in sink_master=mic_denoised_out label=noise_suppressor_mono plugin=/home/krulvis/Downloads/noise-suppression-for-voice-master/build-x64/bin/ladspa/librnnoise_ladspa.so control=0
load-module module-loopback source=alsa_input.pci-0000_00_1f.3.analog-stereo sink=mic_raw_in channels=1 source_dont_move=true sink_dont_move=true latency_msec=20

#update-source-proplist mic_denoised_out device.description="Denoised Mic"

load-module module-remap-source source_name=denoised master=mic_denoised_out.monitor channels=1

set-default-source mic_denoised_out.monitor

This is my pactl list sources | grep 'Name:' output:

Name: alsa_output.pci-0000_01_00.1.hdmi-stereo-extra2.monitor
Name: alsa_output.usb-Devine_Centro2i2o-01.analog-stereo.monitor
Name: alsa_input.usb-046d_Logitech_Webcam_C930e_B67E42EE-02.analog-stereo
Name: alsa_input.pci-0000_00_1f.3.analog-stereo
Name: mic_denoised_out.monitor
Name: mic_raw_in.monitor
Name: denoised

I get the same result if I leave out the module-remap-source line.

Is there any way to properly debug this?

Krulvis commented 3 years ago

I just discovered the problem. The volume of the loopback sink is constantly 0 and as it didn't show up in pulseaudio I never realised. In KMix a loopback from Built-in audio Analog Stereo is shown which was had its volume automatically lowered to 0. As soon as I changed its volume everything worked as expected...

Krulvis commented 3 years ago

Apparently you can just use set-sink-volume which solves the problem for me.

werman commented 3 years ago

@Krulvis I could only say that debugging pulseaudio is hard... It's good that you find a solution.
