I'm on Ubuntu GNOME 16.04 and I've found a solution that works perfectly here: https://wiki.debian.org/BluetoothUser/a2dp On ubuntu user is gdm and not Debian-gdm, here are the exact instructions: In order to prevent GDM from capturing the A2DP sink on session start, edit /var/lib/gdm3/.config/pulse/client.conf (or create it, if it doesn't exist):...

This issue may be related to a problem with Pulseaudio, version 8, as outlined in this (long) thread. Basically, Pulseaudio reroutes the sound when it loses contact with HDMI and doesn't return it after HDMI is reconnected. It is fixed in version 9. In order to return version 8 to the behavior of previous versions, follow the directions found here and ...

Yes, I have the same problem. It was reported on the Dell Community Forums here: http://en.community.dell.com/techcenter/os-applications/f/4613/t/19682246 There seems to be no fix yet, but Dell has "replicated the issue in house", so I expect it won't take too long now.

You can find system sounds in the /usr/share/sounds/ubuntu/ directory. From there, you can change the .ogg files with your own.

White noise is mathematically an even distribution of frequencies. You can produce it with random data from /dev/random or /dev/urandom. If you want to change the "tone" of the produced noise (for example to make it less "weighty" by removing lower frequencies, or to make it "damper" by removing higher frequencies) then you could use a command such as dd bs=...

There's also Renoise, a very powerful multi-platform audio sequencer, though the full version is commercial. The demo version however doesn't have many limitations, and will let you do what you want, and add filters, effects, etc. to the generated sound. http://www.renoise.com True white noise with a lowpass filter, and maybe some chorus and reverb added ...

I recently lost sound on a upgrade. I was able to get my sound to work by running the program "alsamixer" from the command line. My default sound card had changed. I reselected my sound card and checked that the volumes were adequate to get the sound working. You do not say what desktop you are using (gnome3,unity,xfce) so it hard to suggest a graphical ...

I see that nobody has used aplay yet so try the following: aplay --channels=2 --format=S16_LE --rate=44100 --duration=3600 /dev/urandom It is not terribly imaginative so I have added in a timer to compensate :). The duration settings is in seconds so this will run for 1 hour and then turn off, hopefully the baby will have settled by then...

Open Audacity. Go into "Generate > Noise..." Select "Brownian" (way less aggressive than actual white noise). Amplitude and duration does not matter much. Loop using Shift+Play button.

The installed-by-default utility speaker-test generates pink noise (which, as @nightingale, is what you really want, not white noise). It can be set to do so indefinitely by running speaker-test -l 0

FFMpeg has an audio noise source filter. You can play it using ffplay: ffplay -f lavfi -showmode 0 -i 'anoisesrc=color=brown' The arg to -i is interpreted as a lavfi filter graph, because of -f lavfi. -showmode 0 disables ffplay's default audio visualizer window, which it shows by default for audio-only inputs. As you can see from the output of ffmpeg -...

White noise is torture. Especially for the delicate ears of babies. This is because white noise has too much energy in the high frequencies.

Not sure that this will produce real white noise that covers the whole spectrum, but a simple pacat /dev/urandom seems to do the trick on my system (no need to install anything new or add a repository).

I'm a glutton for punishment, so I'll give you the GUI way. Take a look at ANoise. The default sound that it comes with is bad, but you can download other sounds like Forest Rain, Fountain, & Others. You can set it to start with the system, and even set it to stop after a certain time. sudo add-apt-repository ppa:costales/anoise sudo apt-get ...

Use the Swiss army knife for sound generation, SoX. You install it from the official repositories, simply by typing: sudo apt-get install sox Updated, fancy answer (pleasing ocean waves): After experimenting a bit with SoX, I came up with this great command which imitates the soft murmur of the sea with its soothing sound of waves that flow over a ...

Tom Swiss of unreasonable.org uses the following code (using sox) to generate white/pink noise. You'll need to first install sox (sudo apt install sox), then create a shell script with the following code: #!/bin/sh len='7:00:00' if [ "$1" != '' ]; then len=$1 fi play -t sl - synth $len pinknoise band -n 1200 200 tremolo 20 .1 < /dev/zero Hat tip ...

You can generate pink noise using the play command from the sox utilities: sudo apt-get install sox play -t sl -r48000 -c2 -n synth -1 pinknoise .1 60 Adjust the values of .1 and 60 to suit your needs. Pink noise is less harsh on the ear and is hopefully the sound you require

You verify it by: sudo fsck /dev/sdxx It is best to run this in a live cd/usb. Never run it on /dev/sdxx. It will destroy your system. If you can't get a live cd/usb, use recovery mode and drop to a root shell (NOT RECOMMENDED).

Okay, it seems like Canonical fixed the problem for us with one of their latest system updates! Thanks guys! EDIT: Input is still not working (mic/line in).

Although the problem has been resolved, I still want to share another great Linux DVD ripping freeware I love – AcidRIP (https://apps.ubuntu.com/cat/applications/precise/acidrip/).

Unfortunately it is a bug. As an ugly workaround you may press and hold the down volume button until the volume slider goes to zero before taking a screenshot. Here's another related bug.

I had the same problem, could not get sound out of Logitech S-150. When I went into Sound Settings and changed it to USB and closed out, it would still be on HDMI when I went back in. It should stay on whatever is highlighted when you close the window. I ran pulseaudio -k in terminal and that fixed my issue. Now when I choose USB in Sound Settings and move ...

Two-part solution. The first part I found by trial-and-error: Removing the oss4 packages: sudo apt-get remove --purge oss4-base oss4-dev restored my sound immediately. I didn't even have to log out, much less reboot. However, I still had no sound icon. A search on that problem led me here, which told me to install package kmix. I tried it. It didn'...

Invoke (menu) -> Sound&Video-> PulseAudio Volume Control if you have it installed already. Go to the [Output Devices] tab, that's the third one up at the top. Find your output device in the list. Make sure the Green globe-with-the-white-check button to the far right is indented, (shadowy), not unclicked out. This connects your sound to your ...

I created a new user and found that sound works correctly with the new user. That means that something was wrong in user configs. I found some configs and it looks like the problem is solved. The files were not in text format and I have no idea what that format is. I removed all files from ~/.config/pulse/ and rebooted. Now it works OK. I also removed all ...

The easiest solution for Ubuntu 16.04 was to create a script that listens when screen unlocks instead of script that listens to when system wakeups because it seems not all services are available at the instant that system wakes up. I couldn't get pulseaudio to switch to hdmi sound with a wakeup script but have successfully fixed it using the unlock ...

Before wiping out the entire Chrome configuration directory, try this: switch to another audio output device and then switch back to the original one. If you have only one audio device, connect an external one (like HDMI or USB audio) and then perform the above trick.

The script bellow relies on all native tools of Ubuntu, pactl and qdbus to determine active app, automatically mute and unmute as the app gains and focus from user.
