I use lubuntu and have installed pulseaudio and pavucontrol already. I have managed to fix the problem with my microphone noise by launching skype from terminal: PULSE_PROP="filter.want=echo-cancel" skype But I have a question. Is there a way to reduce noise in incoming audio signal in skype using pulseaudio? Evgeniy.

You need newer versions of libmlt6 and libmlt++3 than what Ubuntu 14.10 shipped. 15.04 already has the newer packages. You can work around the problem on your 14.10 system by simply grabbing the newer version from 15.04 and installing them: cd $(mktemp -d) wget ...

I was able to get system sound working by adding my UID to the audio group. I still am not getting audio in Chrome however, but that might just be a bug in Chrome at the moment, as was suggested here. If anyone has any more Chrome specific suggestions, those would still be greatly appreciated.

Please make sure that the /etc/modules has the following script, chromeos_laptop i2c-designware-core i2c-designware-pci i2c-designware-platform If not manually update it and then try rebooting the machine. Hope this helps.

The error Assertion 'p' failed at pulsecore/memblock.c:836, function pa_mempool_block_size_max(). Aborting. means that the program, in a consistency check, found something that is not supposed to happen. Dazed and confused (cit), it is aborting because it doesn't know how to continue. This is clearly a bug of the software, which is an alpha release, so ...

Thanks to Temüjin from ubuntuforums.org this issue has been solved!

Started Pulse Audio. rm -rf ~/.config/pulse; pulseaudio --start Incase if its still showing errors you will have to reinstall pulse audio and equalizer. sudo apt-get purge pulseaudio pulseaudio-equalizer; sudo apt-get ...

I cobbled together stuff from a few different places and came up with this script to set up a bluetooth JAMBOX once it has been paired. Your MAC will be different of course. Since I control the JAMBOX volume via the Clementine app, 130% volume works best in my case. You might want to change this, along with the rhythmbox.png (it was the only speaker picture ...

in alsamixer, try using arrow key Up, then turn everything up to 100% and you will see the right bar turns up. After that turn down arrow key to % you like. Now it should be down together and your right speaker will work on both sides.

The problem is Hydrogen (as Ardour) launch jackd at startup but don't close it at exit: But you can run killall jackd in a terminal after Hydrogen exit. A complicated way to use Jack and pulseaudio software at the same time is to install "pulseaudio-module-jack" (also install qjackctl (gui for jackd) and pavucontrol if not present). Restart ...

chose your speakers as the default output or if you use qpaeq use the one it adds as the source output or uninstall pulse and reinstall it this worked for me when my sound sources wouldn't show

Check the ACPID socket for changes, can be done with the help of python or C or shell script, (Python code for controlling the earphone plugin play and pause on rhythmbox). Check for the changes in ACPID voltage to detect earphone plugin and earphone plug out. A seconds delay can be expected though.

There is a right and left balance control in the GUI interface for sound. Your question seems to indicate you prefer a terminal command, and so if that's the case I can't help you. However if you are merely determined to mute one of your speakers you should be able to configure that in your sound settings. Merely click once on the speaker icon at the top ...

Another option to what Babbzzz answered is to use GNOME ALSA Mixer. It's the exact same thing as the terminal program alsamixer but it is a GUI version. Simply run sudo apt-get install gnome-alsamixer in Terminal (or search for/install it in the Software Center/Synaptic.) Once installed you should be able to launch it from the HUD menu. It provides all the ...

PulseAudio controls underlying ALSA-level volume controls. Open a terminal. Enter alsamixer and press the Enter key. You will now see a user interface like below. Select your correct sound card using F6. Mute/Unmute with the “M” key. An “MM” means muted, and “OO” means unmuted. This was the problem I had once.

Take a look at github.com/masmu/pulseaudio-dlna. It was designed to stream the sound of your applications to DLNA devices in your network. You can choose which application to play on your device via pavucontrol.

Adam's script inspired me too. I created a little server which discovers all upnp renderers in your network and adds them as sinks to pulseaudio. So you can control every application via pavucontrol to play on your upnp devices. Thats the kind of comfort i always wanted when dealing with upnp devices under linux. You can grab it at: ...
