Describe the bug
The nightly now emits "PulseAudioService: pa_context_connect() failed" when you start it, and every 30 seconds thereafter. I am not running pulseaudio.
To Reproduce
Simply start "openscad-nightly" in an xterm.
Expected behavior
No errors emitted.
Code reproducing the issue
N/A - no code needed.
Screenshots
N/A - easy to reproduce.

Disabling the sound notification might help as
@MWStonton
suggested.
Yes, I already had "Play sound notification on render complete" unchecked. Good call, though.
I wonder if there's any options in Qt to change the sound engine or turn it off. It gives me something to Google.
As far as I know pulseaudio is a compile-time option for qtmultimedia 5.
If that is not an option - big disclaimer I haven't tried this, keep a copy so you can put it back, at your own risk etc... - deleting
/usr/lib/x86_64-linux-gnu/qt5/plugins/audio/libqtmedia_pulse.so
might just work.
That is the path from Debian
libqt5multimedia5-plugins
.
Yes, I found that lib and moved it to /tmp, and it didn't help.
/lib # grep -Rls "pa_context_connect() failed"
x86_64-linux-gnu/qt5/plugins/audio/libqtmedia_pulse.so
x86_64-linux-gnu/libQt5Multimedia.so.5
x86_64-linux-gnu/libQt6Multimedia.so.6.4.2

x86_64-linux-gnu/qemu/audio-pa.so
x86_64-linux-gnu/libQt5Multimedia.so.5.15.10
x86_64-linux-gnu/libQt5Multimedia.so.5.15
x86_64-linux-gnu/libQt6Multimedia.so.6
(and pretty much the same for /lib64)
If I move the libQt5Multimedia/libQt6Multimedia libs, then the apps don't start because they can't load libraries. I didn't have any luck finding a Qt user setting.
I've reproduced the messages. It seems they were being output before, after the first render completed. The change is that now they begin on OpenSCAD startup.
Some ideas about what would stop the messages:
Installing and running PipeWire, it can provide a pulseaudio interface.
Switching to Gentoo. Binaries are available now
https://www.gentoo.org/news/2023/12/29/Gentoo-binary.html
. Even if the binary for dev-qt/qtmultimedia:5 is compiled with pulseaudio, it can be compiled with
USE="-pulseaudio" emerge dev-qt/qtmultimedia
(an experimental OpenSCAD build is a challenge though!).
Hm... well I've used OpenSCAD for a while... (couple years) and this is the first time I thought I'd seen this. I usually render a couple dozen times on the way to a final model. Not arguing though.
Anyway, yeah, it's not a big deal, especially compared to the enormous volumes of barf that GIMP, Firefox, PrusaSlicer, etc output from GTK. I didn't know if it was an indication of a problem behind the scenes.
Thanks for taking a look.
Also THANK YOU for the new measurement tools! After getting half a dozen transforms deep, it's nice to be able to say "what is that distance, again?"

I think you are right - I did all my testing with "Play sound notification on render complete" checked (I didn't think about it, enough combinations as it was!). But what that did show is it was always impossible to get any sound with the Qt compiled with PulseAudio support/no PulseAudio combination. Although it probably was a way of avoiding the messages.
Hm. So I just updated to 2024.01.06.nightly, which also pulled in some libboost packages.... and....
No more pulseaudio emissions. Alrighty then. I guess this is no longer a bug!
