Pulseaudio Crossover Rack - multi-way crossover design & implementation with linux

When Pulseaudio has problems..

1. System is sitting for a while, a channel disappears (no output). I click to remove modules, the new default sink is blank. I try again, it appears. I reload, this doesn't fix the problem. I close the crossover and open again, now it works.

I am OK with some problems. What is the fastest/best way to recover from this?

2. System restart. I need to start paxor and load a crossover before it will work. Is this right, should it just work without paxor running?
 
Hey AllenB, sorry for the delay. Forgot to answer...

Please tell me the used pulseaudio version and os.

Also can you please post the output of "pacmd list sinks" at the time the problem ocurrs. And after system startup... And the contents of the file .config/pulse/default.pa when crossover is inserted. Please attach as text files or use a pastebin!

It's OK, I have good tunes :)

Buster
PA 12.2
Paxor 1.46

Sinks before load xo.
Sinks and default.pa after load xo.
Sinks when choose 'remove filter modules' and there is no available default master sink.

ok, Somehow pulseaudio winds up in a state where it doesn't work anymore. can you please post the "console window" output when removing the modules in paxoverrack...

./default.pa, paxor does add and remove the statements the way I would expect it to.

I opened the console, chose remove filter modules, sink was blank so I cancelled, there was no console output until I repeated and chose a sink. I should have tried clicking yes when it was blank, (vague memory I think it won't accept, but I should try again later after it has time to do it again).

Hi, I think have a similar problem to the one below, but am using Linux Mint 19.1 MATE

Hi Jürgen
I have just installed Ubuntu server and the lubuntu desktop on a Pi 2B
When I try to start PAXR it asks and then downloads the pulsectl no problems but then when it tries to add zodb I get this error...
Code:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-6wlywkmc/BTrees/

any suggestions ?

PAXR installs fine, but when I try to run it I get the following error -

WARNING:
Could not find python module 'ZODB'.
Should we try to install it for you?
(This may take a few seconds or minutes.

I click yes to install, it appears to fail and I get the following error -

ERROR: module 'ZODB' not found.
Manual installation: 'pip3 install zodb'

Code:

I can see there are errors in there but have limited Linux knowledge, could anyone help? Is there more information you will need?

Thanks in advance!
 
Hi, I am still struggling to get the program to run,

I wondered if it was a problem with my PC so
I have installed PAXR on a Linux Mint 19.2 Live USB as follows

I am pretty new to Linux so am I making a simple error in the installation?

Or a major one elsewhere? any guidance gratefully received!
 
AllenB kindly suggested that as one of the errors refers to wheel files and they use pip that I should install pip, so here is what I did -

What should I do? Is there a way to completely reinstall python? Does anyone have any suggestions?
 
Reinstalling OS is the windows way. The python2/python3 libraries are installed to different locations, independent of each other. Just install them for python 3 (pip3).


Ahhh, I didnt see your message until I reinstalled Linux Mint 19.2 MATE.

It STILL gives the same errors though and cant install ZODB.

I did however see the following errors during the repository install

Code:
rr:10 [url=http://ftp.cixug.es/mint/packages]ftp.cixug.es[/url] tina Release

N: Updating from such a repository can't be done securely, and is therefore disabled by default.
 N: See apt-secure(8) manpage for repository creation and user configuration details.
Is this relevant? Could anyone help me solve this?


As my linux knowledge is limited I don't really understand what else to do.
 
... The python2/python3 libraries are installed to different locations, independent of each other. Just install them for python 3 (pip3).


phofman, I'm not altogether sure what you meant by libraries so I have installed PIP3 as follows -

I used the instructions from this website - Installing pip/setuptools/wheel with Linux Package Managers — Python Packaging User Guide



Is this what you meant? If you could show me exactly what I need to do I will be very happy!
 
By libraries I mean the packages installed by pip.

So no you have pip3 (pip for python3) installed. Since your error log complained about missing wheel, I would also install package python3-wheel.

Then you can try installing the packages required for paxor, using pip3

pip3 install ZODB

I am no python dev, just this procedure usually worked in my rare cases of using python.
 
:up: Congrats. And you have learned the principles at the same time.

Python3 has brought lots of useful features (python2 is a very ugly language, python3 just ugly :) ), but its incompatibility with python2 (neither backward nor forward compatibility) causes huge mess in the python ecosystem as well as in linux distributions. Some tools assume the default /usr/bin/python symlink is python2, the newer ones expect python3. The years-old mess will stay for more years to come, lots of projects are still python2 only (e.g. the wonderful audio server mopidy).
 
Great work on this t5!

I just got it set up driving my three way jbl/emilar/fostex horn system. I was previously using minidsp 2x4hd when I was 2 way, then was running equalizer app when I went three way. Primarily using Amazon music through Firefox as the audio source.

I noticed on ubuntu 19.10 everything is great until I go into the settings applet/sound and see the audio card is selected even though the paxo input sync seems to be the output device. If I try to change the out device to the output sink for paxo the audio starts looping and essentially makes all the apps really slow until I terminate pulseaudio. Any other reports like this? Using a u7mkii asus card but other cards exhibit the same. Could it be an issue with pulseaudio 13?

As long as I don't go and try to change that - everything works great. So I can live with it.

Any thoughts about adding a convolver?
