Audacious 2.5.0 was released a few days ago, getting some very interesting new features like: option to dock some of the plugins (like album art, visualisation, lyrics) into the GTK interface, configurable playlist columns, support for GTK 3.0 (but the version in the WebUpd8 PPA is not compiled with GTK 3.0 support), a reorganized preferences window, a new New Cairo-based spectrum visualization plugin, new buttons for shuffle and repeat and much more.
For a complete list of changes, check out the Audacious 2.5.0 changelog.
The new option to dock plugins into the interface is a bit tricky so here's how to use it: once you enable a plugin that opens a separate window, under the titelbar there is a small plugin title which you need to right click and then you can select to dock it to the main Audacious interface. I've recorded a video so you can see exactly how to do this:
Install Audacious 2.5.0 in Ubuntu
As usual, the latest Audacious (2.5.0) is available in the WebUpd8 PPA for Ubuntu 11.04, 10.10 and 10.04. Install it using the following commands:
sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install audacious
If Audacious 2.5.0 fails to start for you or you get a segfault when enabling some plugins, remove the Audacious config folder:
rm -r ~/.config/audacious
Unlike other PPAs and the Ubuntu official repositories (Audacious 2.5.0 is not yet available in Natty but anyway), Audacious from the WebUpd8 PPA is built with "libguess" enabled (which provides automatic character code detection) and also, the Audacious Plugins package has PSF support (Playstation Sound Format) enabled.
Note: I've only tested it in Ubuntu 11.04 and 10.10. Even though I still maintain packages for Ubuntu 10.04, I cannot test them!
