Linux test microphone pulseaudio

PulseAudio can combine sounds from multiple sources called mixing. It can change the sound format, increase or decrease sound channels. It can also send the sound of one computer to another computer. You have to make sure that main, restricted, universe, and multiverse software sources are enabled on your Ubuntu Ubuntu You can easily replace it with PulseAudio sound server.

It is available in the official package repository of Ubuntu You can configure the sound output from the Output Devices tab. You can drag the marked slider to the left to decrease the output sound, and drag it to the right to increase the output sound. PulseAudio lets you control the left and right speakers separately.

Just click on the lock toggle icon in the Output Devices tab and you should see two separate sliders as marked in the screenshot below. You can drag them left and right as till you get the result you want. You can control sound input devices from the Input Devices tab. You can drag the slider to the left to decrease the recording volume, and drag the slider to the right increase the recording volume for your default recording device, which is in my case the Microphone.

You can select more devices from the Port dropdown menu as you can see from the screenshot below. Just like for the output devices, you can configure the left and right channel separately for the input devices as well. Just click on the lock icon and two sliders should appear as marked in the screenshot below. You can control what input devices you want to see in the Input Devices tab using the Show drop down menu as you can see in the screenshot below.

If you have many types of sound input devices installed, this should be a good feature for you. As can see from the screenshot below, there are many sound profiles available by default.

Analog Stereo Duplex is the default sound profile.

You can control sounds for individual applications from the Playback tab of PulseAudio Volume Control. You can then drag the slider for that specific application to the left or right to control the sound volume of only that application.

Now I can move the slider to the right to increase the sound volume, or to the left to decrease the sound volume. I can even control the left and right sound channels of VLC player separately after clicking the lock toggle icon as you can see from the marked section of the screenshot below.

You can control your sounds using PulseAudio Volume Control while recording as well.Besides the sound device drivers, ALSA also bundles a user space driven library for application developers. This enables direct kernel interaction with sound devices through ALSA libraries. However, your sound may be initially muted.

If it is, see Unmuting the channels. To allow remote users to use ALSA, you need to add those users to the audio group, however this is not recommended by default see note below. Install the alsa-utils package. This contains among other utilities the alsamixer and amixer utilities. This emulation layer is useful e. If you want OSS applications to work with dmixinstall the alsa-oss package as well.

Then load the snd-seq-osssnd-pcm-oss and snd-mixer-oss kernel modules to enable OSS emulation. The alsa-utils package comes with systemd unit configuration files alsa-restore. These are automatically installed and activated during installation via package provided symlink to sound. Neither will run by default, as they rely on some conscious decisions by the user to know which method should be preferred.

The options are as follows:. Both methods are mutually exclusive and you can decide for one of the two approaches depending on your requirements, for further information see alsactl 1. The alsa-firmware package contains firmware that may be required for certain sound cards e. Creative SB Audigy2. The MM label below a channel indicates that the channel is muted, and 00 indicates that it is open.

The gain can be found in the upper left next to the Item: field. To get full 5. Those are channel names with Intel HD Audio, they may vary with different hardware. To enable your microphone, switch to the Capture tab with F4 and enable a channel with Space. If audio is being outputted to the wrong device, try manually specifying it with the argument -D. ALSA configuration files follow a simple syntax consisting of hierarchical value to parameter key assignments.

Below are modified excerpts from asoundrc. Assignments define a value of a given key.Auto-Mute Mode is a configurable setting from amixer. If one experiences no audio output via any means while using ALSAattempt to unmute the sound card.

To do this, launch alsamixer and make sure each column has a green 00 under it this can be toggled by pressing m :. In setups with multiple outputs e. This will cause amixer to ask PulseAudio to do the toggling rather than toggling it directly. Because of this, PulseAudio will correctly unmute Master as well as any applicable output. If a specific application is muted or low while all else seems to be in order, it may be due to individual sink-input settings.

With the offending application playing audio, run:. Find and make note of the index of the corresponding sink input. The properties: application.

Ensure sane settings are present, specifically those of muted and volume. If the sink is muted, it can be unmuted by:. Try using larger values when changing volume e. This is because PulseAudio uses flat volumes by default, instead of relative volumes, relative to an absolute master volume.

If this is found to be inconvenient, asinine, or otherwise undesireable, relative volumes can be enabled by disabling flat volumes in the PulseAudio daemon's configuration file:. Per default, it seems as if changing the volume in an application sets the global system volume to that level instead of only affecting the respective application.

Applications setting their volume on startup will therefore cause the system volume to "jump". Fix this by disabling flat volumes, as demonstrated in the previous section. When Pulse comes back after a few seconds, applications will not alter the global system volume anymore but have their own volume level again.

However, be aware that it may cause another bug preventing PulseAudio to unmute speakers when headphones or other audio devices are unplugged. If changing the volume in specific applications or simply running an application changes the master output volume this is likely due to flat volumes mode of pulseaudio.A sound server is a background process accepting sound input from one or more sources processes, capture devices, etc.

PulseAudio is installed by default in most Debian desktop environments. Pulseaudio becomes the default when the package is installed. Everything including flash will use it. This can be checked by with pavucontrol in the pavucontrol package.

If the sound is registering in the vu vumetre of that program, then it is being routed through the pulse system.

Basic Configuration Mixers Pavucontrol, an optional package for pulseaudio, allows you to make volume adjustments entire system or per application. It also allows you to change "mixer" settings like headphone output, mic level, input device, and stereo versus surround sound profiles. However, you may not need to install pavucontrol as most desktop environments have their own control panels for configuring Pulseaudio.

Often such programs will not mention Pulseaudio and will simply be called something generic like "Sound Settings". Surround sound system Many people have a multi-channel sound cards, but use the speakers for the two channels.

PulseAudio has no default settings for surround sound support. This is probably unnecessary overkill, but might help some people. It will therefore skip devices already in use by other applications, eg. Front Panel Jacks not working As of wheezy, for some reason, pulseaudio does not see the toggle feature of some cards i.

The trick, for now? Be sure to uncomment the line by removing the leading semicolon. While latency should be low, it should be sufficient to get a feeling of the sound quality as you will hear yourself speak in the microphone. Be ready to lower all volumes in case the microphone picks up the output from the loudspeakers.

Naturally, it is better to run such a test with headphones. On top of this above technique, many conferencing services have built-in echo tests. For example,? Skype has an echo test. These instructions describe how to disable it with the pulseaudio package still installed. Individual users can then reenable it themselves as needed.

Without these files in place, the regular alsa defaults will be used. When you quit the application, the default behaviour of PulseAudio will be restored automatically. Here are some features of PulseAudio High quality software mixing of multiple audio streams with support for more than one entrance source and exit sink.

Hosting provided by Metropolitan Area Network Darmstadt.Before anyone marks this as an already asked question, I seriously am clueless as to what the problem is and googling anything at this point just places me in a loop of articles I've already seen. Story: After some time of my built-in mic not producing any sound, I finally fixed it. But shortly after that, I tried using Qjackctl to play some music through my microphone.

At that point, I didn't touch any settings in pavucontrol or in Alsamixer. I eventually stopped using Qjackctl, closed it and decided to use my microphone. It was producing no sound at all. All it detects is my headphone's microphone, which doesn't work CM audio controller. Anyways, fast forward to googling a ton of things and trying a lot of them, my built-in microphone isn't even detected anymore. It happened straight after restarting pulseaudio.

You can see in the second picture that I have some activity on my "Monitor of CM audio controller" but that seems to be the music I'm currently listening to. As you can see, no built-in microphone is present in the settings. How exactly did you "finally" fix it? That wording looks like you've consciously done something but you aren't specifying what exactly.

I've packaged up other people's answers into 'listen', a Bash script. Run this to listen to your mic input. It sleeps forever. Kill it e. Ctrl-C to stop listening.

Just an update for if you use gnome. There's a gnome extension that you can use to achieve just that. You can use audacity to amplify your voice by "playback while recording" feature. Mixxx is awesome! I'm using it on Ubuntu Budgie Quick setup, just turn it on, set up your hardware I only had to set up the input device and turn on the mic.
