Thanks for the report,

This is now fixed for the next release

See 127889
Update to 2.0.44 which should mitigate the issue and wait for 2.0.46 for a proper fix.

Thanks for the report. Initially I wanted to put this under Minor issues as "that's just how walking sounds are done" but then I couldn't un-hear it and it bothered me, so this is now fixed for the next release, 2.0.46.

The identified issue is fixed (by a rework of how audio resources are handled, which should prevent these kind of issues popping up in the future) for the next release, 2.0.46.

Quick update: I have identified a place in which an audio resource is leaked and I have a fix in the works, it should be fixed on the next release but I will post again once that is for sure.

Edit: To give some more context. The issue would happen when opening/closing GUIs of machines with sound ...

Those sounds were adjusted in 2.0.45.

Thanks for the report, however the crash is happening in a place that is not (directly) under our control (it's crashing in an audio driver provided by SDL).
Given it doesn't happen all the time using the same setup, it was probably some unusual situation with audio devices (re)connecting, as you ...

The change will be in the next release, 2.0.44. Thanks for the report.

With the next release, 2.0.44, there will be a mitigation in place trying to reclaim the leaked resources. It will also log warning when such resource is reclaimed, so I ask if you could update to that version when it's released (you need to opt in for experimental releases) and post your logs after ...

I've forwarded this to the sound designer.

There seems to be a leak of audio resources due to some bug. When that happens new sounds can't play.
I currently have no idea what is causing it. These kind of bugs are very tricky to figure out as it happens over a long(-ish) period of time and it might not be specific to Fulgora (maybe it just ...

Music playing on technology screen is intended, not a bug.

Factorio doesn't affect other applications and it doesn't do anything with sound on losing focus. It sounds like something else on your system is trying to do something clever based on what's open. If that is the case it's outside of our ...

Sounds like you can reproduce this issue. Next time it happens, can you record a clip with the "show-detailed-info" debug option as well?

Edit: And if you have a save file in which it is easy to reproduce, post it as well, please.

Edit 2: In the log I can see you have changed your preferred audio ...

Minor Features

Added support for volume and speed activity matching for persistent working sounds.



What does this mean?


The volume and/or playback speed can be influenced by entity's activity rate. Activity rate is a general concept telling you how active an entity is (it means ...

Just a little update, I have received a cleaned up version of the track from the composer so both in-game and standalone OST can be updated. It might take a while to actually get it released though. I'll keep you posted.

Thanks for the report.
The issue was related to variable music tracks and their threads. The threads could be sleeping when the track was ordered to stop, the game would wait for those threads which could lead to a noticeable stutter.

Similar stutter could occur if you press "Play next" while a ...

Thanks for the report, I must have missed it at the time.
This issue should be fixed since 2.0.16.

If the headphones are the default audio device (and stay default after disconnecting and reconnecting) the audio backend should do its best to resume playing sound through that device.
If you explicitly selected your headphones as the preferred output device in Factorio sound settings it might not ...

It could also be a case of the GPU going into lower power state and then reporting higher utilization percentage even though it doesn't do any additional work, looking at power consumption of the GPU might be a better indicator. But this is also just a wild guess.

Thanks for the report, the issues is now fixed for the next release, 2.0.39.
