7 months ago I dumped the output of load_pw_modules.sh to a log file, there's one error that stands out:
+ pw-cli -m -d load-module libpipewire-module-xrdp sink.node.latency=2048 sink.stream.props={node.name=xrdp-sink} source.stream.props={node.name=xrdp-source}
+ pw-metadata -n settings 0 clock.force-quantum 2048

+ pw-metadata -n settings 0 default.clock.min-quantum 4096
+ pw-metadata -n settings 0 default.clock.rate 44100Seemingly pw-metadata -n settings 0 default.clock.quantum 4096 returns an error.
However, after that I tried to run the commands above, and this time no error:

set property: id:0 key:default.clock.min-quantum value:4096 type:(null)Maybe there's a race, since as we can see here:
pw-cli -m -d load-module is called and sent to background, and then we have a sleep 1... So maybe the pw-metadata commands are called too early after that....
I tried a few times to log in and out, and it's not 100% reproducible. Sometimes there's no error, sometimes there are more errors, and the output suggests that, for some reason, we don't get stderr in time, so we don't know which command caused it. Example:
+ pw-cli -m -d load-module libpipewire-module-xrdp sink.node.latency=2048 sink.stream.props={node.name=xrdp-sink} source.stream.props={node.name=xrdp-source}
+ pw-metadata -n settings 0 clock.force-quantum 2048
+ pw-metadata -n settings 0 default.clock.force-quantum 4096

While discussing packaging this repo for Debian at https://alioth-lists.debian.net/pipermail/pkg-utopia-maintainers/2024-March/034881.html, there was some feedback from Dylan (maintainer of the pipewire package in Debian):
The diff mentioned above is about the removal of
default.clock.force-quantumas « force-quantum doesn't exist in context.properties » according to Dylan.I suppose it wouldn't hurt to run the script
load_pw_modules.shin a console, there should be one (or more) error messages to hint at what needs to be updated.
