Tue Mar 5 2019:
[11]Version 4.0 released. Changes:
* There can now be only one pavucontrol window open at a time. Trying
to start pavucontrol for a second time brings the first window to
foreground.
* Added a "Show volume meters" checkbox to the Configuration tab.
Disabling the volume meters reduces CPU use.
* Improve the use of space (remove useless margins and paddings).
* Use a more appropriate icon for the channel lock button.
* Better channel label layout, prevents volume sliders from getting
unaligned.
* Maximum latency offset increased from 2 to 5 seconds to accommodate
AirPlay devices that often have higher latency than 2 seconds (this
is not that useful on newer PulseAudio versions, though, because
the latency is reported much more accurately than before).
* New --version command line option.
* New translations: Chinese (Taiwan), Croatian, Korean, Norwegian
Nynorsk, Lithuanian, Valencian.
* Updated translations: Finnish, French, German, Italian, Japanese,
Polish, Swedish.
* Dropped support for Gtk+ 2.
* Bumped the minimum supported libpulse version to 5.0.
* Improved compatibility with newer Glade versions.
PulseAudio Volume Control (pavucontrol) is a simple GTK based volume control
tool ("mixer") for the PulseAudio sound server. In contrast to classic mixer
tools this one allows you to control both the volume of hardware devices and
of each playback stream separately.
