Can't get Pipewire virtual surround to work "Jack buffer size change"

Hello, I'm following this guide: https://gitlab.freedesktop.org/pipewire … processing

All the steps seem to work fine but locking the quantum does not seem to work. The setting changes but it still displays the error "Jack buffer size change, exiting."

$ pw-cli create-node adapter '{ factory.name=support.null-audio-sink node.name=hrir-headphones media.class=Audio/Sink object.linger=1 audio.position=[FL,BL,SL,FC,FR,BR,SR] }'
1 = @proxy:52

$ pw-metadata -n settings 0 clock.force-quantum 256
Found "settings" metadata 30
set property: id:0 key:clock.force-quantum value:256 type:(null)

$ pw-metadata -n settings
Found "settings" metadata 30
update: id:0 key:'log.level' value:'2' type:''
update: id:0 key:'clock.min-quantum' value:'32' type:''
update: id:0 key:'clock.max-quantum' value:'8192' type:''
update: id:0 key:'clock.force-quantum' value:'256' type:''
update: id:0 key:'clock.force-rate' value:'0' type:''

$ pw-jack jconvolver -s pipewire-0 ~/virtual-surround/gsx-jconvolver.config
Jack buffer size change, exiting.

I've tried setting the buffer to high values, including its max, and to low values, but neither changes things.

I've Googled this issue but found nothing helpful. I'm not sure how to troubleshoot it.

Using the command pactl subscribe reveals no errors when starting the convolver

$ pactl subscribe
Event 'new' on client #84
Event 'change' on sink #59
Event 'change' on source #65595
Event 'change' on sink #41
Event 'change' on source #65577
Event 'change' on card #39
Event 'remove' on client #84
Event 'change' on sink #41

Event 'change' on source #65595
Event 'change' on sink #41
Event 'change' on source #65577
Event 'change' on sink #59

Any help would be appreciated. smile
