Reboot your machine and your audio will be good to go, ready to play your favorite tunes, meme videos and whatnot.I have sound on my ubuntu20, I can play any audio but the problem is when I'm using speech recognition, alsa doesn't work properly.

Then, run the following command: sudo apt install pulseaudio alsa-base alsa-utils We want to only uninstall those specific packages, and since we are reinstalling them in a few seconds, there's no need to worry about missing dependencies.
Alsa vs pulseaudio driver#
The very simple processĪs long as your audio configuration and settings were working when you installed Ubuntu, and the malfunctioning state is caused by your misconfiguration and/or fault, restoring the audio driver to default state might actually be helpful.įirst of all, completely purge and remove your pulseaudio and alsa packages by running: sudo dpkg -purge -force-depends pulseaudio alsa-base alsa-utilsĭon't worry about dependency warnings - we are aware of that that's the purpose of bypassing apt. Pulseaudio vs ALSA Post by FeralUrchin » Tue 1:31 am It is well-known now that pulseaudio breaks ALSA apps (in my case a video editor by screwing up the timing of the audio stream). It felt like magic, when everything suddenly started to work. I had a brilliant idea: I could bypass apt entirely and use dpkg. That's obviously something you do not want to uninstall. You will be greeted with an awesome list of dependency packages that will be removed too, and those will include ubuntu-desktop, ubuntu-desktop-minimal and other completely unrelated system stuff. However, if you try: apt autoremove -purge pulseaudio I had the idea of trying to completely purge and reinstall the pulseaudio and alsa* packages. Disabling timer-based audio scheduling ( tsched=0) helped a little, but it didn't fix the issue. My configuration file wasn't changed, nor was the system one. I knew something was messed up, but I really couldn't figure out what. My last chance was to try and fix PulseAudio. Also, NoiseTorch was listing every one of my inputs as (incompatible?) - they were working fine a few minutes earlier. I finally got it to work - however, the video stream was freezing every few seconds, and the audio in my headphones was popping and crackling like crazy. Anyway, I started tinkering again, I installed the droidcam-dkms package but it failed, I tried uninstalling it but it removed everything. On Linux, sound servers, like sndio, PulseAudio, JACK (low-latency professional-grade audio. Most of the 'mushiness' from Pulse comes from the default fast-and-dirty mixing and resampling methods it uses. ALSA is released under GPL-2.0-or-later and LGPL-2.1-or-later. Pulse uses ALSA as a backend while providing a mixed sink for applications in a multitasking environment.
Alsa vs pulseaudio Bluetooth#
I wanted to use a Raspberry Pi to act as a Bluetooth audio receiver or my Hi-Fi.

Apparently, the v4l2loopback-dc module got removed somehow. ALSA provides the low-level hardware sink with no default mixing. Install alsa, pulseaudio 1) Firstly, both the Pi 4 and Pi 400 have two.

I was getting the error Device not found (/dev/video). This morning I had to attend an online lesson - and whoops! DroidCam was no longer working. Since we all have to attend online meetings these days, I have worked on my setup too, which consists on two main things: DroidCam, to make my phone into a webcam, and NoiseTorch, to remove anything that is not my voice from my audio stream.Įverything worked smoothly for a few days, until I installed a kernel update.
Alsa vs pulseaudio windows#
I've recently began using Ubuntu 20 as my daily driver, and as I started migrating everything from my Windows installation, I finally got to the audio and video department. TL DR - I don't care about your cool story, just give me the commands: click here.
