Please describe your issue in as much detail as possible:

I have no sound. I can see the audio devices in game, but it does not matter what I select, there is no sound. pw-top does not show cs2.

Steps for reproducing this issue:

1. Start cs2
2. no sound

[Rosentti]

Beat me to it. :D

[kacperoo29]

Seems like everyone is on the same boat - for me I am getting some devices in sound settings, but the names look like something I would get on Windows instead of Pipewire and some devices are missing.

[Rosentti]

I'm only getting my microphone's (output?) and some HDMI devices...

[hogcycle]

+1 also having sound issues with Pipewire.

[hogcycle]

Got audio for a bit when messing with output devices but it didn't hold after a restart. Hoping valve sees this and fixes it quick.

[alou-S]

It seems like the issue is caused by CS2 not being able to use either Pulse or Pipewire API natively.
It directly connects to the ALSA Backend which is generally not a good thing since then Pipewire won't be able to use it when CS2 is connected and vice versa.

But yeah audio technically works but not in a viable way.

[tralph3]

Using ALSA directly means the game takes full control of the audio device, which doesn't let any other application use it until its released. Pulseaudio and Pipewire exist specifically to fix that problem (among other things).

[hogcycle]

Anyone have a workaround yet?

[kiwec]

Also using pipewire here.

CSGO used to use pulseaudio when you passed SDL_AUDIODRIVER=pulse as env var. But this no longer works. It also doesn't use jack so you can't use pw-jack either.

[Zipdox2]

What audio library does it use? I think with OpenAL maybe we can set the backend with an environment variable.

[Zipdox2]

SDL_HINT_AUDIO_DRIVER=pulse doesn't work. 😢

[gibarel1]

can confirm, no audio on my end either. Although i can select what looks like my headset as output it does nothing
steam system info

[idarlund]

Same issue here. Pipewire as well. Any workaround?

[moxw]

SDL_HINT_AUDIO_DRIVER=pulse steam

This worked for me!

[Zipdox2]

SDL_HINT_AUDIO_DRIVER=pulse steam

This worked for me!

Doesn't work. Can you give more details on how you ran this?

[moxw]

SDL_HINT_AUDIO_DRIVER=pulse steam

This worked for me!

Doesn't work. Can you give more details on how you ran this?

I just started steam using that, and opened the game. Got the sound.

[gibarel1]

SDL_HINT_AUDIO_DRIVER=pulse steam

Can confirm, did that and selected the audio source until it worked.

[Rosentti]

There seems to be a startup option -sdlaudiodriver, but I'm currently in a match so I can't test.
The game seems to use sound_device_override forced to Source2SDLDefaultDevice.

[moxw]

SDL_HINT_AUDIO_DRIVER=pulse steam

This worked for me!

Well, you are only able to use cs2 audio, other outputs don't work.

[offsetcyan]

Same using bluetooth audio. None of the options so far, including launching Steam with SDL_HINT_AUDIO_DRIVER=pulse have worked.

[RuedigerDieter]

Same problem here:
I'm using pipewire, and testing with my speakers connected to the mobo I am getting sound (most of the time); using my headphones via USB DAC, I'm not getting any in-game sound. Also, the audio stream does not show up in pavucontrol like I'd expect it to.

[returntoreality]

I was able to get sound after adding -sdlaudiodriver pipewire to the commandline

[Zipdox2]

There seems to be a startup option -sdlaudiodriver, but I'm currently in a match so I can't test. The game seems to use sound_device_override forced to Source2SDLDefaultDevice.

[gibarel1]

SDL_HINT_AUDIO_DRIVER=pulse steam

Can confirm, did that and selected the audio source until it worked.

Tried to relaunch steam withou any variables to test other solutions but now it sound works even without the parameter. Will try to see if restarting the system messes it up again

Edit: confirming, restarting messes it

[alou-S]

This issue seems to be present in the latest Dota2 Update (Compendium). So yeah it should be fixed soon.

________________________________________
Also the people who the envars fix the problem, the problem isn't truly fixed. The game is just simply being able to directly use the ALSA backend because Pipewire disconnected from it.

[Kaydax]

Putting -sdlaudiodriver pipewire works perfectly for people using pipewire, not sure about pulse but it may be -sdlaudiodriver pulse or -sdlaudiodriver pulseaudio. However for people using jack, -sdlaudiodriver jack does not work and causes the game to state that sound is disabled

I tried running the game with pipewire-alsa, and you still have to choose between hearing the game or hearing everything else

Using the default device routes everything through PipeWire as it should, but it doesn't do anything in CS2

using the launch option "-sdlaudiodriver pipewire" in CS2's property menu in steam should allow you to hear audio from more than 1 application, works for me.

[epicbattle1]

the sound is broken for me on pipewire with -sdlaudiodriver pipewire launch option after today's update, could anyone else test it?

[af7567]

I just downloaded the lastest update and sound is working through pipewire with -sdlaudiodriver pipewire OK for me. After 1 game of premier it was still OK with no delay (at 44100Hz)

ok, seems like a problem on my end, thanks for answering

[sylware]

SDL3 audio is currently under heavy developement, expect breakages, and they really broke it for alsa.

The right way on linux is all games, game engines have only 1 API to care of: the native alsa-lib. The actual software mixer [jack/pulseaudio2(pipewire/gwireplumber)/pulseaudio1/dmix] is hidden behind the alsa API as it should be. jack & pulseaudio2(pipewire/gwireplumber) & pulseaudio 1 are hidden behind an alsa-lib PCM plugin.

I did fix to a recent git SDL3, here:
https://transfer.sh/e9OV53rxIT/libSDL3.so.0 it should work for most alsa user.

[sylware]

oh, and it tracked there for SDL3:
libsdl-org/SDL#8577

dota2 and cs2 uses the same linux runtime.

[DominikM60]

Adding -sdlaudiodriver pipewire gives me false hope by working until about 30 seconds into the match. To fix that I have tried to change the sound device and whenever I try it the game completely crashes. To test out if that's an issue only related to Linux i set up Windows 10 on other disk. On Win10 it is even worse as game crashes completely out of nowhere at the moment when on Linux I would lose the sound.

[sylware]

Look at the SDL audio issue right above, I finished my ALSA audio code contribution.

I have been playing dota2 with alsa dmix multi-channel enabling with it (and testing very little with cs2, namely only the title screen).

[stefan11111]

When I open cs2, by usb headset doesn't show up in the audio output list.
I can set the output to my laptop's onboard sound card, which works, but I can't set it to my headset because it doesn't show up.
I use pure alsa(no pulseaudio or pipewire).

/etc/asound.conf:

defaults.pcm.card 2
defaults.ctl.card 2

[sylware]

@stefan11111 as far as I know, SDL3 devs are still reviewing/merging/debugging/etc my alsa code. No news from them, weird as some other fixes went it very fast (like the input bug).

[sylware]

@stefan11111 I can upload to you a libSDL3 build which is "supposed" to work with cs2 (it works on my system), if you trust my binary.

[stefan11111]

Sure.

[sylware]

There, it was linked with a glibc 2.33:

https://transfer.sh/IaIfxX40q2/libSDL3.so.0

Hopefully it will work for you too (this is omega alpha code), and it is working now, 20231205.

[stefan11111]

Which one should I replace:

$ locate libSDL3.so.0
/home/stefan/.local/share/Steam/steamapps/common/Counter-Strike Global Offensive/game/bin/linuxsteamrt64/libSDL3.so.0
/home/stefan/.local/share/Steam/ubuntu12_32/libSDL3.so.0
/home/stefan/.local/share/Steam/ubuntu12_64/libSDL3.so.0
/home/stefan/Downloads/libSDL3.so.0

Also, my system has glibc 2.38-r1. Will the lib work?

[stefan11111]

@sylware
Unbelievable, it actually works! Thank you.
I've had some experiences with steam issues on linux, and they never got resolved to quickly.
Got yourself a new follower.

The lib I replaced was /home/stefan/.local/share/Steam/steamapps/common/Counter-Strike Global Offensive/game/bin/linuxsteamrt64/libSDL3.so.0(after backing that up, of course).
Note that, the "Default Device" doesn't actually work, but the usb headset I have does show up in the menu and that option works.

Since you seem knowledgeable about steam, do you know exactly what dependencies proton needs in order to work?
I have tried to run some games via proton, but even the simplest games fail to launch.

[sylware]

@stefan11111

Glad it works (for now...). I works for dota2 as well.

info: A more recent glibc can run binaries linked with "older" glibcs, but very often (and sometimes certainly), binaries linked with a "recent" glibc won't run on systems with "older" glibcs (most of the time for not really pertinent reasons). That's one of the reasons which make building wide "glibc" spectrum binaries something "hard" (don't expect that from "normal" game devs).

The alsa canonical "default" is actually set by the alsa lib included in the "pressure-vessel" steam runtime (for dota2 and cs2), it may not import your configuration (I use the ALSA_CARD environment which is going thru the container, but I have not tested /etc/asound.rc or $HOME/.asoundrc).

Sorry I am a #noproton guy, I have a lean vanilla git wine/vkd3d... and since it seems (until proven otherwise) proton does include copies of microsoft windowns DLLs, I don't use it. I rarely have something working though (but I got a few interesting windows games working).

[stefan11111]

Replying to #3256 (comment)

Could you please tell me how to use ALSA_CARD to set the soundcard?
I have 3 sound cards, one is the internal one, one is the nvidia hdmi audio, the third is my usb headset, which is listed as card 2.
What envvars do I need to pass to steam in order to set my sound card to the usb headset?

[JohnDoe02]

I have the rather special problem, that the sound cuts off after a while (can be anything, from 30sec to even 10-15 min on the server -- usually, within 2-5 min though) when playing on the deathmatch servers of warmupserver.net (pipewire 1.0 on arch linux). On Valve deathmatch or premier/competitive everything works fine. I tried everything from -sdlaudiodriver alsa/pulse/pipewire, forcing 44100hz system-wide to even switching back to pulseaudio. Sadly, to no avail.

Once the audio cuts off, I can get it back by switching back and forth with another sound device. However, once I do so, the game tends to crash shortly after (sometimes, the game crashes directly instead of the audio cutting off).

I have not tried other non-official deathmatch servers yet. Ah, and Windows works fine of course.

[kisak-valve]

Closing because the issue reported here was fixed in late September 2023.

If anyone is seeing follow up issues, those issues should be tracked separately.

[akumaburn]

-sdlaudiodriver pulse launch option alone worked for me

[SamuelGogarty]

-sdlaudiodriver pulse launch option alone worked for me

is this an issue again?

audio still works for me

[XandarNull]

issue is not fixed please reopen

[stefan11111]

issue is not fixed please reopen

Still working here on my gentoo system.
what is your setup?

[Fesiug]

I still need to use -sdlaudiodriver pulseaudio to ensure that sound always works, I wouldn't say the issue is fixed unless this is set as the default or some other solution is implemented

[stefan11111]

I have tested cs2 on a pure alsa system without any launch options and sound still worked.

Maybe you are hitting the sound card .asoundrc issue?

[Fesiug]

No clue, I run a pretty normal Arch install with PipeWire as my audio server and haven't tinkered with that file.
