Works flawlessly for me, but I'm running on Arch. Maybe somebody running the same distro as you can test.

Hey buddy, try to see whether the audio is outputting to the correct device. As you have Kubuntu, go to the system sound menu, while the game is running, and check if the application is outputting the audio to the device correctly.

Can confirm. Game works here apart from audio. Details

• Ubuntu 18.04

• i7 3770k,

• gtx 970, drivers: 396.51

• Pulse audio: 12.2

• Pulse effects: 4.2.8

• libopenal1: 1.18.2

I did some research myself and I found the following things:
PulseAudio never receives any audio. Doom is mentioned within the playback devices, but there is never any input reported.

When I start the winecfg, I can do an audio test which shows that audio works. @whiskersnout you can test your wine-audio by starting winecfg

WINEPREFIX=/DIRECTORY/Steam/steamapps/compatdata/379720/pfx winecfg

Audio is broken for me in all games for me since the update today. Nothing in pamix (console mixer for pulse) and doesn't work with pure ALSA either.

Eonfge: Checking winecfg won't tell the entire story since that will use your system Wine, rather than the Proton one. I'm not sure where that is stored, however.

@thirdeyefunction winecfg is telling (most of) the entire story here; the command line from the comment above yours temporarily sets the system WINEPREFIX env variable so that winecfg reads from Proton's configs as opposed to your system's normal wine configs. It's reset as soon as the program ends.

This isn't the correct explanation, but it works well enough for what's going on here.

As for the bug itself, I remember running into this issue with PulseAudio before; for whatever reason PulseAudio doesn't like to register apps that attempt to play sound at the same time the first frame is sent to the GPU. You may be able to temporarily fix it by delaying either PulseAudio 2 frames or delaying the game executable by 2 frames, but it's an ugly hack and should not be used in release builds (as doing so can mess with a lot of sensitive drivers, and cause some devices to crash or hang)

@commandhat Yes, but the test itself relies on the system Wine executable to run (unless you explicitly run Proton's wine executable with winecfg following). If there is a problem in Proton's Wine executable, rather than its configuration, that would not be seen.

So I've come to discover that the no audio only occurs when attaching my Bose USB speakers. Audio functions correctly when using the HDMI via RX 480, or when using the direct audio connectors on the motherboard.

Can add to the information, I'm Using a Cooler Master Sirus 5.1 headset which is connected to my machine using a USB Mixing console (fancy word for volume nob).

@kisak-valve Issue might be resolved with proton 3-7.6

I first had this issue with both Doom 2016 and Rage, after which I used my own workaround to get Doom running. Now with 3.7, Rage audio works. I'm a little apprehensive to Reinstall Doom just to validate this bug, but it might be resolved.

@Eonfge backup your prefix for Doom. Delete it. Restart steam. And verify file intergrity. It will redownload a fresh prefix.

@LeJimster I tried that but I had no success.

I did discover a few other things:

• Following me previous workaround, installing winetricks packages was actually not required. Only setting the sound=alsa was enough.
• When I tried to load my previous save file, it was corrupted.

Reproduced case once more on 3.7-8:

• Ubuntu 18.04
• i7 3770k
• GTX 970, drivers 415.18
• PulseAudio 12.2

Also, the Alsa trick I used before doesn't work. Using also now, I get crackling and disrupted audio.

Edit. Trying to set sound=pulse does reveal the following:

Works in 4.2-6 with my setup.

@whiskersnout Could you validate and close the issue?
