pulseaudio-dlna is a lightweight streaming server that makes it easy to stream audio from a Linux computer that uses PulseAudio, to a DLNA / UPnP or Chromecast device in the same network.

Using it, can for instance switch between headphones, speakers and HDMI sound output with just two clicks. Or switch between several sound devices (sinks) without having to go to System Settings > Sound, etc.

I've uploaded the unofficial system-wide PulseAudio equalizer to main WebUpd8 PPA for Ubuntu 14.04 Trusty Tahr. 

Update: the equalizer was updated to support Ubuntu 16.10. The PPA now supports Ubuntu 16.10, 16.04, 15.10, 15.04, 14.04 and 12.04, as well as Linux Mint 18 and 17.

The package update comes with a fix for a crash that occurred when no presets were found. The issue that caused audio to be muted as soon as PulseAudio Equalizer was enabled, disabled, or adjusted, was also fixed.

By default, in Ubuntu and probably other Linux distributions, if you're playing music in Rhythmbox, Audacious and so on while receiving a call in applications such as Skype, Ekiga Softphone, SFLphone VoIP Client and other VoIP applications, the music continues to play even after answering the call. PulseAudio has a feature that allows pausing or muting the music when receiving a call, but it's not enabled by default, at least in Ubuntu, so here's how to enable it.

About two years ago we had an article about a system-wide Pulseaudio equalizer. This tool is still used today but it's no longer developed and it doesn't work properly for everyone, so many users have been looking for alternatives.

Well, I'm not sure if you're aware of this, but Pulseaudio has, for a while, its own built-in system-wide equalizer. However, the Pulseaudio packages available in the official Ubuntu repositories are not build with equalizer support. In Ubuntu 13.04, Pulseaudio is finally build with equalizer support but the actual equalizer is missing from the package for some reason, even though it's available in the source.

So, to make things easier for you, I've create a PPA for Ubuntu with Pulseaudio built with equalizer support and with the actual equalizer enabled.

Today I was updating most of the packages in the WebUpd8 PPA that I didn't update yet (not many actually) for Ubuntu 11.04 Natty Narwhal and I've remembered about some patches for PulseAudio Equalizer so I though I'd add them with this update.

Back in February we had a post on a system-wide Pulseaudio equalizer which still works great in Ubuntu Karmic and Lucid, but doesn't start in Ubuntu 10.10 Maverick Meerkat.

The official Pulseaudio System-Wide Equalizer PPA does not provide Maverick packages but in theory you could download and install the Lucid package and run it in Maverick just fine. However, that's not the case because of an icon (yes, just an icon!) which has been renamed in Ubuntu 10.10 which causes the equalizer not to start in Ubuntu 10.10 Maverick Meerkat and you'll get this error:

If you're experience bad sound with the default WINE package in Ubuntu and have Pulseaudio working, you should try the following WINE package (available in an Ubuntu PPA) which comes with built-in Pulseaudio support. This is especially useful if you use Spotify under Wine in Ubuntu.
