fairly new to Ubuntu and I've spent the last couple days working to get everything set up and running as smoothly as I can. I wasn't getting audio through my motherboard sound-card, and was following  troubleshooting guide, which ended up solving my problems. However, I now have a bunch of programs that weren't there previously. My question is do I need them, and if not, how do I go about removing them?   They are as follows -   Echomixer Envy24 Control HDAJackRetask HDSPConf HDSPMixer Rmedigicontrol   I hadn't used any of these during my audio troubleshooting, (only used Pavucontrol in the end) but figured I'd ask first.  I have also tried purging a few through terminal commands by their name, but would receive "Unable to locate package." Not sure what to do.     I'm on 18.04.1, if that's relevant.

Simple enough question: is there some shell command (or GUI method) I can use that, given the path to a file on my system, tells me what package put it there? Assuming the file did in fact come from a package, that is.  Bonus question: what if it's a file that isn't installed on my system? Is there, say, a website that will let me look up a file and see what packages, if any, provide it?

There is a radio station that intermittently plays through my headphones when they are plugged in. It does not play through the stereo speakers of my laptop.   When I open the volume mixer, it does not show any sound being played, even though there is sound coming through my headphones.   The sound does not get louder or quieter when I change the volume.   I have closed all browsers, and the sound still comes through.   How can I find a list of all programs that are outputting sound?

I have a setup where I am monitoring for silence on an incoming stream on 3 different audio cards.  When I detect silence on the master I switch to the secondary, and if I detect silence there I switch to the last card.  The way I have it set up I load/unload the loopback module for each card depending on who's the active card.  This has the inconvenience that I need a 3-to-1 minijack cable to be able to maintain the stream.  Can I load the loopback module and point the output to a single card (independently of the input card)?  How can I route the audio from any input to a single output?

There's a &quot;default beep&quot; (as defined in System Sounds) that emanates from my computer every so often. It kind of goes like this (where each number is a &quot;default beep&quot; sound): 1, 2, 3, 4,  5. So there's a distinct pattern to it. I thought I had this figured out a way to figure out what was happening by going to Control Panel-&gt;Ease of Access-&gt;Ease of Access Center-&gt;Replace sounds with visual cues But that just isn't the case.  Whichever window I click on, that one displays the visual queue when this happens. It's driving me crazy, and I can't figure out which program is causing this. Update: it appears to only happen on one user profile on the computer...does that help? Update 2: Discovered that this sound was coming from a utility on my laptop called ASUS NB Probe; I'm certain that it is emanating from this program because the error message displayed by it changes in sync with the sound playing. Apparently the  feature of my hard drive was reporting an issue. It displays the issue for a brief second and then makes it disappear, I'll have to keep watching it to see what it says, but I believe is says something about a read. I have an external hdd connected with eSATA to a container of sorts (BlacX) that you can plug two hdds into. I have one hdd attached and it's a Western Digital WD1001FALS - 00E8B0 Thanks again!  Now I'm off to go around the Internet and report on this...since I posted it so many places!

I recently installed a fresh install of Ubuntu 11.10 64-bit on my notebook.   I personally prefer Rhythmbox over Banshee so I searched for and installed it from the Ubuntu Software Center. (including all plugins that were listed). Unlike previous versions of Ubuntu (11.04, 10.10, etc..) the (previous, play/pause, next) controls have been removed from the sound menu. Rhythmbox is still listed (above "Sound Settings...") but when clicked all it does is open the application. To add insult to injury the Banshee controls are displayed right above it - even though that application isn't running.   I have tried opening Rhythmbox from the Unity dashboard, the Unity launcher, and the sound menu with the same results. I've also verified that I had rhythmbox-plugins installed. I even tried to remove and install the application. Still no controls.    It looks like they were removed and that we are now expected to use Banshee. Why?  Here is a screenshot of what my sound menu looks like when I'm playing a file in Rhythmbox. (Notice that Banshee isn't running but it's controls are displayed) In Ubuntu 10.10 and 11.04 Rhythmbox had controls just like Banshee's controls in the screenshot.

At each reboot, PulseAudio sets a sink (in my case, "HDMI Audio Output") as the default.  So, at each reboot, I don't hear any sound, and need to reconfigure the default sink each time to "Analog Output".  How do I remove/disable a specific sink such as HDMI, or set a default sink that overrides the existing sink?

Every time I plug in my headphones, Ubuntu shows a popup box asking whether I've plugged in headphones, a headset, or a microphone.  How do I get it to stop doing this?

Does anyone know how to programmatically capture the sound that is being played (that is, everything that is coming from the sound card, not the input devices such as a microphone).

I have some apps that I want to record the output sounds locally before outputting to speaker, Bluetooth or any other output. So I get clean unadulterated audio, before any audio output mods.  My devices are rooted, some have custom ROMs.   Is there a way to do this internally, without any programming/coding knowledge? Can this be accomplished? Preferably with out hooking to PC as that prevents local saving.   include steps.  include references      Please excuse lack of tags, limited on choices.

What are ways to install/uninstall programs in Ubuntu. I will mention only .deb since it is the official package format and for example installing a .sh or .run program can typically be as simple as (In latest Ubuntu) ./program.sh or sh program.run.  Also note that am talking about HOW to install packages IN Ubuntu, not talking about downloading a new installer (Like some Super Cow Software Center Duke Nukem version from sourceforge or something). Only tools that already come in the repositories (In any of the 4 standard ones, main, universe, restricted or multiverse).  Take into consideration all GUI and terminal ways of doing it, with basic format of doing the installation. With this in mind I am talking for example about Software Center, synaptic, apt-get, aptitude, dpkg, etc... a way to show all tools that are available in Ubuntu to install deb packages.  NOTE - Forgot, this should be Community Wiki since it will have all ways a user can install/uninstall something. Like a friendly guide on doing that.  UPDATED question to remove the confusion some are having about sh/run files.

I am wondering if there is a way to uninstall all "programs" installed by Homebrew? I was using it and installed programs that corresponded to programming or using C/C++ and used the terminal to compile it but will not be using it in a few months.

I installed Ubuntu 12.04 a month ago and am using it till now. I failed to notice that all this time there was no sound at all while running Ubuntu, even while playing a game in Wine. The weird thing is that only the startup sound comes when I log in (Indian/African drum tone), then comes the utter silence.  I tested both Digital Output (S/PDIF) and the speakers in the sound settings but can hear nothing.  Any help?

After installing 12.04 Precise on my PC, I have encountered some problems with audio output which did no occur when using Lucid.   The sound is choppy and distorted in the lower tones. As I have no experience in setting/testing and doing anything with Audio Devices, I need help even to diagnose the problem.  Update  $ sudo lshw -c multimedia    *-multimedia           description: Audio device        product: Radeon X1200 Series Audio Controller        vendor: Hynix Semiconductor (Hyundai Electronics)        physical id: 5.2        bus info: pci@0000:01:05.2        version: 00        width: 64 bits        clock: 33MHz        capabilities: pm msi bus_master cap_list        configuration: driver=snd_hda_intel latency=32        resources: irq:19 memory:fdafc000-fdafffff   *-multimedia        description: Audio device        product: SBx00 Azalia (Intel HDA)        vendor: Hynix Semiconductor (Hyundai Electronics)        physical id: 14.2        bus info: pci@0000:00:14.2        version: 00        width: 64 bits        clock: 33MHz        capabilities: pm bus_master cap_list        configuration: driver=snd_hda_intel latency=32        resources: irq:16 memory:fe024000-fe027fff   Update 2  It has something to do with the volume. If the audio is quiet it is not choppy, if the sound is loud then it begins to be choppy.

Since my Cinema Display is both connected through mDP and USB, I can (stupidly enough) both choose “LED Cinema Display” or “Display Audio”.  Also, I never use the internal speakers since they sound extremely tinny.    How do I remove/delete/disable unwanted audio devices? It must be possible somehow!

Sound Problem - No Audio Input is Shown i.e Microphone is not Visible ,neither the "Headphone" profile is available !  I have Headphone connected and I can hear voices coming out of it !  I suspect Cadence or GLadish is responsible for this  ! Please help. I also suspect resetting all audio related settings to back to its factory state will solve this issue !! But I dont know how to do that !?

I want to use echo cancellation for my Skype calls and Empathy on Ubuntu 12.10 (pulseaudio 2.1).   Does anyone know how to do that?

I have had trouble with sound (now fixed) since upgrading to 19.10, and in the middle of trying the common solutions, the Software Center "disappeared". I got aware of quite late, so I don't know what caused it.  Anyway, would you know how to reinstall it ? Trying sudo apt-get install software-center doesn't work.
