Perhaps a known issue, but it appears that the Pulseaudio environment will be replaced by Pipewire in the July 12 update.
At this time, piepwire-pulse conflicts with manjaro-pulse and tries to remove manjaro-pulse, but this replacement fails because of conflicts with its proposed packages pulseaudio-jack, pulseaudio-lirc, pulseaudio-rtp, and the dependent This replacement fails because of conflicts between the proposed packages pulseaudio-jack, pulseaudio-lirc, pulseaudio-rtp, and the dependent package pulseaudio-zeroconf.
Will Pulseaudio no longer be supported by Manjaro?
If so, it would be better to remove manjaro-pulse and replace it with manjaro-pipewire.
(Personally, I do not want Pipewire to be forced upon us.)
This update included pipewire-pulse because easyeffects added pipewire-pulse as a dependency package, which conflicted with pulseaudio.
(I forgot that easyeffects had been installed for the dependency package used by pulseeffects-legacy.)
By removing easyeffects (and manually installing calf, etc.) I was able to update it.
Stable Update announcement of 2022-07-12 has 3 comments that appear to be blaming PulseAudio for creating dependency problems.
But there were no PulseAudio packages included in the update, So any problem with dependencies must be from another package update and comments are scapegoating the wrong package (again)
