If your microphone still doesn't work, there may be a physical problem with your microphone. Depending on factors like your level of expertise, and the design of your specific laptop, you may want to try and open your laptop to examine the microphone at this point.
Alternatively, you could either take the laptop in for professional repairs or purchase an external microphone or headset to get around the problem. If you want to physically examine your microphone yourself, here's what you'll have to do:. If you have a Lenovo laptop, try these tips. If your laptop microphone still doesn't work, and you don't see anything wrong with it after physically inspecting it, then you may need to take your laptop to a professional. The microphone might have gone bad in a way that you can't see just by looking at it, or there may be another repair that requires professional expertise or special tools to fix.

HDA Intel. Now press F5 to display all items. Try to find the item: Input Source. The microphone and the audio jack are duplexed. Set the configuration of the internal audio in pavucontrol to Analog Stereo Duplex. Some applications e.
If we are getting static noise in Skype, gnome-sound-recorder, arecord, etc. That is why there is static noise in Linux microphone recordings. This requires alsa-utils and related packages to be installed:. The sound card is hw: x , y where x is the card number and y is the device number.
In the above example, it is hw:0,0. We aim to find the highest sample rate supported by the hw:0,0 sound card using a trial-and-error procedure starting from a low value. When the top value is reached, we got a warning message:. Let us record some voice using a microphone for, say, 10 seconds. Make sure the microphone is not muted and all. Another possible cause is that your mic has two channels but only one channel can provide a valid sound signal.
Some information can be found here. The solution is to remap the stereo input to a mono input:. Now arecord hopefully works. You may still need to change the RecordStream from setting to Remapped Built-in Audio Analog Stereo of a specific application in the Recording tab of pavucontrol.
This happens because these applications capture the microphone as mono only and because remixing is disabled, Pulseaudio will no longer remix your stereo microphone to mono. If your microphone volume creeps up automatically and causes the sound to be distorted, you can fix it by disabling mic boost:.
Sometimes ALC chips have crackling sound while recording using a microphone. Some Pulseaudio configuration changes may help:. This tells the module to use various DMA pointer fixes. Use trial and error to determine which value works for you.
If you are unsure about your microphone setup, you can hear the input from the microphone in real-time by enabling the loopback module source :. The module will show up in the Recording tab of the pavucontrol program, where the source and volume can be configured.
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. To make the change permanent, add the following pulseaudio configuration:. Watch out for feedback! 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. The newer implementation of the PulseAudio sound server uses timer-based audio scheduling instead of the traditional, interrupt-driven approach.
Timer-based scheduling may expose issues in some ALSA drivers. On the other hand, other drivers might be glitchy without it on, so check to see what works on your system. Time-based scheduling may be causing this, disable it as explained in Glitches, skips or crackling.
Another reason you are encountering static noise in your headphone jack could be ALSA's loopback mixing. Make sure you have alsa-utils installed, launch alsamixer , then select your audio device pressing F6 , navigate all the way left using the left arrow , and stop on Loopback , if Enabled disable it using the down arrow.
This should not impact audio playback or microphone recording negatively, unless you require loopback mixing. Some notebook models, like Dell XPS 13 , suffer from continuous hissing sound when a headphone is plugged in. Yet another reason for this symptom could be the power-saving mode of your audio device.
This article or section needs language, wiki syntax or style improvements. See Help:Style for reference. By default, PulseAudio uses timer-based scheduling. In this mode, fixed-size fragments are not used at all, and so the default-fragments and default-fragment-size-msec parameters are ignored.
Instructions below will cause PulseAudio to use a fixed size and number for audio fragments. These settings directly affect latency and power consumption. The considerations are:. If one does not care about excessive power consumption, then 2 or 3 fragments, 5 ms each, are a reasonable choice.
Restart the pulseaudio. Run your applications, listen to the sounds they produce, inspect the journal.

To check and change your default microphone:. Make sure your app has access to the microphone. For privacy reasons, you can set it so that only certain apps are able to access the microphone.
If your chat or conferencing app doesn't have permission, it will seem like the microphone isn't working. This setting works similarly in Windows 10 and Windows 8, but there is no corresponding setting in Windows 7.
Skip this step if you are using Windows 7. To check and fix this issue:. If you're using an external microphone, unplug it and plug it back in.
Laptops are designed to automatically switch between the built-in microphone and external hardware when it's plugged in. Try unplugging and plugging your microphone back in if you're trying to use an external microphone, or try plugging an external microphone in and unplugging it if you're trying to use the internal hardware. Doing so may cause the software to finally switch to the correct microphone.
Make sure your microphone device isn't disabled. Using the device manager, you'll want to make sure that your microphone is actually enabled. In your Zoom meeting, click on the " Start Video " icon in the bottom left corner.
In your Zoom meeting, click on the " Stop Video " icon in the bottom left corner. Change Camera Sometimes you may need to switch the camera that is being used.
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. Changing the Event Sounds volume in KMix or another volume mixer application will not help here.
If all else fails, you can try to disable flat-volumes:. If audio generally works, but stops after resume from suspend, try "reloading" PulseAudio by executing:.
This is better than completely killing and restarting it pulseaudio -k followed by pulseaudio --start , because it does not break already running applications. If the above fixes your problem, you may wish to automate it, by creating a systemd service file.
Enable it for your user account i. Then restart the pulseaudio. Install alsa-tools and use:. Set "Not Connected" to everything but the ports you are using. It seems the other unused audio ports on the motherboard interfere with the used ones. Then if you want use the Boot Override to save this change between reboots.
There is a possibility it is the Front Green Headphone that is causing the bug, if you need it override the Front Microphone to Headphone and the Front Green Headphone to "Not Connected" and use the Front Microphone port as your headphone port. More info about this problem: [2]. This might cause some sound crackles when changing volume, in that case you might want to leave that option enabled and tweak the deferred-volume-safety-margin-usec and deferred-volume-extra-delay-usec options instead.
If everything worked correctly, you should now see your mic show up when running pavucontrol under the Input Devices tab. If PulseAudio uses the wrong microphone, and changing the Input Device with Pavucontrol did not help, take a look at alsamixer.
It seems that Pavucontrol does not always set the input source correctly. Press F6 and choose your sound card, e. HDA Intel. Now press F5 to display all items. Try to find the item: Input Source.

Jan 17, Hello, I recently experienced no sound on my laptop and I couldn't understand why. I tried all the quick fixes I found online and nothing. I was even about to download a new driver altogether but luckily I found the problem before that Turns out my playback options had switched which was really stupid so this is what I did. On the bottom right hand side of my tool bar I located my volume control and right clicked. When the menu popped up I clicked on the sound option and once that menu appeared I went all the way to the top where there are 3 tabs and clicked on the first one which is playback.
Once there I had two options one which was digital device and speakers. Mine was on the digital output device which had it wacked so I clicked on speakers ,apply, and okay and wah la my sound was magically working again. Anyways Im not sure every body's problem is this simple but just maybe.
I hope this was helpful! See more. You helped me too. Thanks a lot!!!! Sorry but this didnt work for me, only one option came up which were the speakers.
