Since I'm not getting more of the same reports for broken audio on windows and this thread is getting quite stale, I'm moving this to resolved.
Let's make new threads for any new issues on the current version.

I'm glad it's working for you. I consider this resolved then.

Ok, good, I consider this resolved then. I will keep in mind the apulse usecase and try to check it the next time we're updating SDL.

Hello,
Would using SDL's ALSA driver be an option for you? You should be able to force it by setting the environment variable

Thank you for the report. When a pipe is placed down and the water sloshes around, a pipe can go inactive for a tick and its sound would start fading out and fading back in next tick when the pipe is active again. There was an issue with the volume calculation while fading, it is now fixed for the n...

i would like to contribute to this thread and saying i have nearly the same issue but with the main difference im not connecting or disconnecting any audio devices. I have my headset set to default in windows but the connected Microphone and TV provide alternative audio outputs. For some unexplaina...

Recently I was working on updating to SDL 2.24.0(1) but a different issue made me reconsider, so currently the 2.0.22 is used.
I'm looking at the recently released 2.26.0, if there are no issues I'd like to update to that soon.

Thank you for the report. We checked the sound interaction of underground and regular belt and we consider it working as intended at the moment.
So it's somewhere between 'Won't fix' and 'Not a bug' with some 'Minor issue' sprinkled on top.

0.201 [Audio] Backend:SDL(default); Driver:alsa, Device:Default device, Depth:16, Channels:2, Frequency:44100 Not sure if its a problem, but I have "pulseaudio" at that position Backend:SDL(default); Driver:pulseaudio,... Using the ALSA driver is not a problem necessarily. The PulseAudio ...

Did it behave differently with the different audio drivers you tried or with disabled audio?

There's a lot of moving pieces going into this, and it will be different on different platforms. For example, even prior to 1.1.71 release, on my Windows setup, both SDL and Allegro backend would use whatever device was marked as "default". When I plugged in for example USB headset or blue...

The updated drivers are out now in version 1.1.71.
Can you check if you're still having the issue?

With version 1.1.71, the SDL and its audio backend has been updated to a newer version. Could you try out the new version and see if it helps? Also, version 1.1.70 introduces preferred audio output device setting. You should be able to switch to a newly connected audio device while factorio is runni...

With version 1.1.71, the SDL and its audio backend has been updated to a newer version.
Could any of you who had audio issues try out the new version?

With version 1.1.71, the SDL and its audio backend has been updated to a newer version. Some of you have already tested it (or a similar build) and it solved your issues. I cannot guarantee that it solves all issues everywhere but I'm moving this thread to Resolved. I would ask people that still hav...

There is an issue with audio on Linux for some people (see viewtopic.php?f=182&t=102982).
Next release should address this, in the meantime you can try setting your audio backend to allegro.

It looks like it might be the same issue, but I'll wait for your confirmation before merging the topics. It could be something else.

By first run I mean starting the application for the first time and fully closing it, suspending wouldn't be enough.
Is the music playing, same as in this report: viewtopic.php?f=7&t=103957 ?

Hello, Recently I was doing a lot of disabling/enabling/unplugging/plugging of various audio devices, so I can tell you right away I can't reproduce your issue (could be system dependent, as I'm on Windows 10). However, I'm currently in the middle of updating all our audio drivers (and probably addi...
