I'm running Arch with USB Audio - Sabaj.
Strangely, options in Viper4Linux GUI are not clickable , so I cannot change anything.
Eg. Clarity box is checked and I cannot uncheck it, the same with the bass etc....
Equalizer is chosen but if I pick different one and click Apply, the previous one appears...
Do not know where to look for solution...

Help me with the
location=$your_alsa_sink_path_here
I don't understand it completely. How can I find my alsa sink path.
I am getting this :
/home/ishan/bin/viper: line 16: kill: (11015) - No such process Setting original sink to full volume... Failed to get sink information: No such entity Changing primary sink to Viper... Moving existing audio streams to Viper... ERROR: from element /GstPipeline:pipeline0/GstPulseSrc:pulsesrc0: Internal data stream error.

When I stop viper.sh the master volume rises to 100%

This has given us more jump scares than we would like. Whenever I load Viper4Linux on my arch system, it does not respect my volume levels and instantly changes it to 100% which is quite loud. I use some 120W Logitech speakers, so it is loud enough to wake up the dead!!!! Other times, I can not get any sound upon launch and the only way to bring the sound is to do a reload through the app which then the volume maxes out.

Is there a way to prevent this from happening other than ensuring my master volume on the speakers with the hardware volume control is down to zero??

Hey I noticed there's a small typo that might confuse linux newcomers

in Manual section step 2

git clone git clone https://github.com/Audio4Linux/gst-plugin-viperfx    

which probably should be

git clone https://github.com/Audio4Linux/gst-plugin-viperfx    

Hey,

Viper4Linux stopped working on my ubuntu 19.10 setup.

here is the output i get on gui:

Dont know where to start troubleshooting, i ve uninstalled and re-installed following the steps on the main github documentation, no luck. still doesnt work.

thanks

Hi. I'm on KDE-Mint. I figuered, that Vpier works, but only if I set the Input of the audio-playing app to "Viper" and the gst-launch-Playback to the inbuild speakers.
Problem is. Everytime I start viper or a media app, it sets the gst-launch-stram to "Viper", and I have to manually adjust.
Can I change something in the "viper" file to make this setting immanent?
Thanx for your effort

I'm trying to get this to run on Fedora 27 (and yes I'm a linux noob, but I'm eager to learn). Maybe somebody can help me out.

Fedora specific

This are all the different commands I had to run compared to the current README.

Dependencies

sudo dnf install @development-tools gstreamer1 gstreamer1-devel gstreamer1-plugins-base-devel gstreamer1-plugins-bad-free-devel autoconf automake libtool

This means I'm using gstreamer 1.12.4-1.fc27. Could this be (one of) the issue(s)?

Installing the plugin

sudo cp libgstviperfx.so /usr/lib64/gstreamer-1.0/

Problem

The viper script seems to throw a SIGSEGV, but I do see the viper sink after starting:

--
        Name: alsa_output.pci-0000_00_1b.0.analog-stereo
        Description: Intern geluid Analoog stereo
--
        Name: viper
        Description: Viper4Linux

Run output

$ viper start
Setting original sink to full volume...
Changing primary sink to Viper...
$ Caught SIGSEGV
Spinning.  Please run 'gdb gst-launch-1.0 7217' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.
^C

$ viper status
Not yet fully implemented.
There is a pidfile. Gstreamer may be running at pid: 7217.
There is an idfile. The viper sink seems to be loaded at id: 52.

Any idea how to debug this? The viper.log seems to be empty.

Hello,
did you managed SIGSERV error on ARM machines? I just compiled the library, but it throws up with an error:
$ ./viper start Killed process. Deleted pidfile. Unloaded Viper sink. Setting original sink to full volume... Changing primary sink to Viper... Moving existing audio streams to Viper... $~/Viper4Linux$ Caught SIGSEGV Spinning. Please run 'gdb gst-launch-1.0 15676' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.
However, when I check on that
./viper status it says, there is a process and viper sink seems to be loaded.
I don't know if it eventually works, or not? If there is an error, I suppose, it doesn't.

The machine is Orange Pi Zero with Armbian (Debian for arm devices).

my /etc/viper4linux/devices.conf :

when i run ./autogen.sh
i get an issue
autoreconf: Entering directory

I found a solution on another forum which suggested adding the following to the end of configure.ac

AM_GNU_GETTEXT_VERSION
AM_GNU_GETTEXT_REQUIRE_VERSION

whice leaves me with

I used yay -S viper4linux-git to get most of the work done.
then configured device.conf with desc="Speakers" location=alsa_output.pci-0000_00_1f.3.analog-stereo
When started viper gives this:

I used yay -S viper4linux-git and viper4linux-gui-git.
then configured device.conf with desc="Speakers" location=alsa_output.pci-0000_00_1f.3.analog-stereo

I Copied the text basicly form an other post because i have the same problem, but reboot didnt helped me. I also tried to delete the devices.conf file. didnt helped at all, i have this problem like for 1year on Manjaro KDE

Hi I have installed this app and the first thing i immediately noticed is that when the FX is enabled the audio doesn't work how can i fix that?

I have installed this using Yay
System Info:

I'm new to using this app and I don't know what to do.

I've installed viper4linux via zypper and there's no audio output. And I did up the master volume from gui - not sure of what other changes I might have to do. Please help

Found a feature bug, but it looks like if viper is activated while a voice input program is running, it will process the mic input along with any other system input and force it through the viper stream. This results in odd behavior where all viper input (like computer audio and music) are also routed to the mic application (such as discord.) So please be aware, if you start Viper after these applications, the people you are talking to may be able to hear your computer audio.

TODO: Add feature for blacklisting audio streams for being processed by viper.

If anyone wants to submit some code for resolving this feel free, otherwise I am just leaving this issue for my reference.

Great plugin, i found that i was missing the following:

sudo apt-get install libgstreamer1.0-dev
sudo apt-get install libgstreamer-plugins-base1.0-dev

These were required to get ./autogen.sh to run.

Best,
Rob

I have tried both countermeasures by editing files and restarting pulse. no good. sound is good for a while then it would skip. different intervals, 6 to 25 seconds so no buffer related. any ideas?

Hi, thanks for your work.
System: Artix Linux (Arch) with XFCE
Language: German

Installation:

I installed viper4linux-git from AUR.
It depends on

• gst-plugin-viperfx-git
• libviperfx-nonfree-bin

After that, it said no element "pulsesrc"

I googled quite a bit to find that i had to install

• gst-plugins-good

Could you add it to your readme as dependency for Arch?

The issue:

with pactl list sinks | grep "Name: " i get

Name: alsa_output.pci-0000_28_00.1.hdmi-stereo-extra1
Name: alsa_output.pci-0000_2a_00.3.analog-stereo

After first time starting viper, there was no folder "viper4linux" in .config, so i created it.
Following your readme, i added

desc="Speakers" 
location=alsa_output.pci-0000_2a_00.3.analog-stereo

but i get

~]$ viper start
Setting original sink to full volume...
Sie müssen einen Senkennamen/-Indexwert und einen Portnamen angeben
Changing primary sink to Viper...
Moving existing audio streams to Viper...
~]$ WARNUNG: Fehlerhafte Leitung: Kein Element »device«

So, is the format of the sinkname wrong? What portname?

Hello.

I have seen on OBS, that there are packages available for Tumbleweed and Leap 15.1. Are there any plans on setting up a repo for 15.2 and future releases?

Thanks.

Sorry if this is the wrong place but is there more documentation on how to edit the audio.conf file? I have no idea what the abbreviations mean. I would like to add more bass and diable the surround effect which is leaning to one channel.

make command outputs this

Is there a resource of some sort I could read up on to understand all the options that viper has to offer and what they mean/do?

If you like it, please feel free to copy the changes. I can make my repo private, if you include the changes. You can also change it to load it from config, just change in Viper4Linux/viper the dynsys parameters to

dynsys-enable="$dynsys_enable" dynsys-ycoeffs="$dynsys_ycoeffs" dynsys-sidegain="$dynsys_sidegain" dynsys-xcoeffs="$dynsys_xcoeffs" dynsys-bassgain="$dynsys_bassgain"
