kandi X-RAY | pamixer Summary
This is a curses interface for pulseaudio. It is far from complete, but it's already very useful to conveniently move around sink inputs, and adjust volume levels individually. This package depends on argparse and libpulseaudio. The bindings were made for pulseaudio 0.9.22, so they probably crash and burn for older versions.

QUESTION
I have a script that prints my volume status. It checks the output of pactl subscribe
to determine when something has changed. Currently I'm doing this with a while loop, and after the script has been running for a certain period of time (I can replicate quickly by holding a key to toggle mute for about a minute), the only output is "/usr/bin/grep: Argument list too long"
I've tried using < <(pactl subscribe)
, piping into the while loop, and also reading from a fifo. None of these work. Is this expected? If so, what would be the way to handle something like pactl subscribe
that prints infinite output? Since the first error mentioned ponymix, I thought it might be an issue there, but using pamixer instead fixes nothing either.
The full script is here. Here is a relevant excerpt:
...ANSWER
Answered 2019-Jul-19 at 00:33The issue is that inside the print_volume
function, I was repeatedly sourcing a file with export
s in it. As pointed out by Charles Duffy, this caused the environment size to be too large.

Install pamixer
You can use pamixer like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
