when i chose stem export ardour get crash and close the all windows
edit : i use ardour 6 compile from this source https://community.ardour.org/srctar on avlinux
First question is going to be if you get a crash when using the pre-compiled binaries from this site?
If you happen to be using jack and have pulse bridged to jack: The most common cause for a crash on export I have seen is exporting with pulse->jack bridging. The pulse modules jack source and sink will try to satisfy the clock on any alsa device pulse can see. I have found turning all device profiles in pulse off and using jack as if it was the only audio “device” for pulse works fine. The pulse-jack bridging modules in pulse really need a rewrite to fix this, but that is not likely to happen with pipewire set to replace pulse.
this method work after i restart pulse audio in Cadence
