PulseAudio: Audio Files Don't Play in Video Sequencer #88507
Operating system: Linux-5.4.0-73-generic-x86_64-with-glibc2.28 64 Bits
Graphics card: AMD JUNIPER (DRM 2.50.0 / 5.4.0-73-generic, LLVM 10.0.0) X.Org 3.3 (Core Profile) Mesa 20.0.8
Broken: version: 2.93.0 Beta, branch: master, commit date: 2021-05-21 18:43, hash:
Worked: (newest version of Blender that worked as expected)
P.S. I downloaded this version:
May 23, 02:59:17 - blender-v293-release - d5c3bff6e774 - tar.xz - 149.34MB
P.P.S. Is it supposed to say
d5c3bff6e7, which is the same as the May 22 build?
And my bug report says "commit date: 2021-05-21". And the splash screen doesn't say the specific version. It just says "2.93.0 Beta". I tried using the latest daily build of 2.93. I'm new to reporting bugs.
P.S even though this is the same as a previous bug report, that previous report is marked resolved from 9 months ago. But it apparently isn't resolved, at least in the version of Blender I used.
Previous similar bug report:
Short description of error
No sound in video sequencer preview.
Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
Boot blender with factory startup. Modify editor type to "Video Sequencer". Add an m4a sound file to frame 1. Press play animation button. No sound is played. mp3's don't work either. Moving audio strip to another channel doesn't work, either.
But both m4a and mp3 works in Blender 2.92 stable.

Changed status from 'Needs Triage' to: 'Needs User Info'
Which sound system are you using? Its located at Preferences > System > Sound > Audio Device.
Audio Device was set to PulseAudio (in both May 23 and May 24 builds). I changed it to OpenAL - OpenAL Soft, which is what stable Blender 2.92 was set to, and now sound works for both audio formats (in both builds).
So, I guess set the factory default audio device to OpenAL - OpenAL Soft, please?
You can try updating the pulse audio library, that at least helped here #87584. I Agree that PulseAudio was set a little to quick to default, even though it makes sense as a linux default.
Also see #88089 and #86923. Maybe you can also reproduce the crackling in the audio played by other programs.
@A-Mix-of-Geek-Stuff could you try if this build works with pulseaudio (!) on your system: https://builder.blender.org/download/experimental/blender-3.0.0-alpha+master.a112adf16a06-linux.x86_64-release.tar.xz
Also: which linux distribution are you using?
Hi. It doesn't work right away. I have to change the Audio Device in Blender from PulseAudio to OpenAL - OpenAL Soft.
Here's the Linux I'm using (Zorin OS Lite):
stanley@stanley-MS-7593:~$ uname -a
Linux stanley-MS-7593 5.4.0-77-generic #86~18.04.1-Ubuntu SMP Fri Jun 18 01:23:22 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
stanley@stanley-MS-7593:~$ lsb_release -a

Description: Zorin OS 15.3
P.S. Sorry, I didn't try updating my pulse audio library, and not sure how to do that or where to start.
I haven't heard of this distribution before. Does it even run PulseAudio? Could you try e.g.
pactl list as command in a terminal and see if it outputs something? If that works, you can also try playing something with
paplay <filename> where filename should be the path to an audio file (wav or ogg ideally, mp3 doesn't work, at least for me) and check if that works.
@neXyon I pasted the pactl list output into the attached text file.
paplay works for both wav or ogg.
Here's the website for the OS distribution I'm using:
Note that I'm using the Lite version, which uses XFCE. The main paid version uses a different desktop environment iirc.
Okay, so you have pulseaudio and it works for other applications. Can you start playback in blender and then check if it shows up in pavucontrol (the pulseaudio volume control application, you might have to install it)? For me it looks like this:
Maybe Blender is assigned to the wrong audio device or so?
I have the same problem on Gentoo - no sound from Blender.
It defaults to pulseaudio. I can change that setting as I please, but if it is set to pulse and I then play a video with sound trying to change this setting afterwards will freeze blender (kill -9 ..).
If I first change it to e.g. "OpenAL", then sound will be played as expected.
With both settings Blender shows up in pavucontrol, but with "audio device" set to "pulseaudio" the level meter in pavucontrol is "silence" while playing any video in Blender.
Edit: I am using Blender 2.93.1
yes I can confirm the issue happening on Manjaro Linux , no sound, plus that it works well once it changed to openAL, so exact same issue but I am using latest blender 3 and I am on diffirent distro than @blendsnicely
So yes the problem is still active. The only problem is not happening in Blender 3 is the freezing
Changed status from 'Needs User Info' to: 'Needs Triage'
I assume this bug has been fixed with the recent changes to the PulseAudio backend. Please try to switch back to Pulse from OpenAL and feel free to reopen this bug or open another if you still have issues!
