Bug No sound from unity application

Hello, new user here... I have no sound from the unity editor, inspector, or game.
I have checked that unity is not muted, audio is enabled in settings, volume is not 0.
If I open sound files they can play with a different application but the don't play inside the unity editor.
Other applications/chrome play sound normally.
I don't see any errors in console.
I have tried oog and wav files.
In Ubuntu sound settings I dont see "unity" but I see "fmod ex" and the volume is high.
I have tried opening a new project.
I am using Ubuntu 22.04 and unity 2022 LTS.
Anyone have this problem or know the solution? Thanks.

 

It's normal for Unity to register as FMOD Ex.
Which format are your sound files? Did you try with a Wav file?

 

Ok good to know that fmod ex is normal. I tried with oog and wave files but had same issue on both audio file types.

 

If you installed Unity using the unofficial flatpak package then it might be a right issue. You can use an app named Flatseal to check if Unity is allowed to access audio. If you installed Unity using the official package then this won't be an issue.

If everything else fails then the only thing left to do is to check Pulse Audio. I tried doing it on my machine but I can't because I'm on Fedora and Pulse Audio was replaced by Pipe Wire (I checked and Unity 2022 audio works here). So I can't guide you on how to do that. But I can recommend this page which has very good explanation on how to diagnose audio issue. The list-sink-inputs thing is probably what you need. Good luck.

 

Thanks for the suggestion - although I will note that I have not found the solution yet.

My Unity was installed with unity hub and instructions on main site - not flatpak.

I checked with pulse audio, with:

pacmd list-sink-inputs

and I did not see anything out of ordinary regarding the mute/volume settings of the FMOD Ex App.

 

I am also running into this. I believe it started when I upgraded from 2021.3.28f1. I am running Pop!_OS 22.04 LTS. I have tried switching audio output to no avail. When I build the game for Linux, I can not hear any audio. The Windows and OSX versions are fine.

Unity was installed via Unity Hub. Version: 2022.3.10f1

 

Downgrading to 2021.3.28f1 fixed my audio issues.

 

Thanks, downgrading from Unity 2022.3.9f1 to Unity 2021.3.30f1 worked for me.

 

You should report a bug. Especially since the player is also affected and not just the editor. Unity will want to fix this.

 

Thanks. I already did and meant to add that to my update, but forgot. They said "has been confirmed and transferred to the appropriate internal development team at Unity."

 

If you have any link to the bug so I can follow the official fix, please let me know.

 

I'm also running into this issue in Unity 2022.3.5f1. No audio at all from Unity. Tried everything I can think of and it's not solveable for me. Will downgrade to the 2021 LTS version and try that

 

Unity 2022.3.13f1 there is no sound in the editor. Building WebGl project - sound ok, focus work correct ok. POS OS last version. Please Help. 2019.4.40f1 - Editor sound work ok, Building WebGl project focus not correct work.

Fix Problem Sound PopOS.
1-Open Pulse Audio
2-Open Configuration
3-(Configuration) Disable HDA Nvidia
4-(Configuration-Soundcard Mainboard Intel)
5-Editor Sound Play OK - Unity 2022.3.13f1

Sorry Up post. Error actual. FMOD send sound HDMI Port, Please Help set default FMOD output sound Speaker Audio.

 

Sorry, I am just now seeing your post. Unfortunately, the link that Unity emailed me does not even give me access to views the ticket:

Same here!
Unity 2022.3.15f1 and higher.
Ubuntu 22.04.3

pacmd list-sink-inputs

shows:

0 sink input(s) available.

No issues in Unity 2022.2.12f1 and

pacmd list-sink-inputs

shows:

1 sink input(s) available.

Any update from Unity team?

 

Got exactly the same problem... I am on Ubuntu 22.04, using unity 2022.3.13f1. First of all - I have no idea how the hell it worked, but I changed output sound configuration from 5.1 to Analog Stereo Output - and sound is back!

EDIT:
And after some time it breaks again...
Changing settings back to 5.1.. And the sound is working again.. So, it seems ubuntu correctly sets audio outputs for a time if you change settings, and then something redefines them again.

 

Have also encountered this bug in version 2022.3.10f1. In most cases it could be fixed by installing pavucontrol, selecting Playback tab and choosing the correct output sink for FMod Ex.

In one case we dont see FMod Ex when the unity app is running and pacmd list-sink-inputs is empty. Will try to downgrade to see if this solves the issue.

 

Same problem(Unity 2022.3.16.f1 & Unity 2022.3.17.f1)
But I can add a few weird details, clicking play won't play audio, but if I keep certain buttons on the screen checked, like the buttons on Inspector and the ones in the red box below:

Keep these buttons selected and the audio will start playing. This must be a bug of the editor.

 

I can confirm this is still happening in Unity 2021.3.34f1. At least in standalone builds. It was a known issue for 2021.3.32f1 (release notes) but it disappeared in the next versions without a fix.
I had to downgrade to .30 to fix it.

 

Hello guys. In my case, the audio was being sent to the wrong sink:

wrong sink: sink: 0 <alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo-output> (Audio Interface)

should be: sink: 2 <alsa_output.usb-0600_USBFC1-MAX-00.analog-stereo> (My headphones)

So this was not a Unity bug (at least for me). I had to change the output device of the FMOD X from my desktop environment settings (KDE PLASMA) like in the following pictures:

 

When you start a regular software it should by choose whatever you have configured as default system output device. If the Unity intentionally overrides the default and chooses wrong device, while all other software are using the correct sound output device, that's a Unity problem.

I am guessing that this is the issue https://issuetracker.unity3d.com/issues/linux-no-audio-output-when-playing-audio

The release notes for 2021.3.31 mentions "Fixed a bug with surround sound hardware not being detected on Linux". I am guessing that part of the "fix" involved forcefully picking any surround output device or requesting a device with surround capabilities instead of using default one. Which is equally likely to cause issues as fixing them, since there is no guarantee that that's the one you have currently attached speakers or headphones to.
