In FreeBSD 14.0, following the instructions given in this post, my case is the same, strawberry only works if I remove the sndio package. It turns out that sndio is necessary to open the ungoogled-chromium browser, because without it the browser doesn't work!
Other programs like smplayer, and ogg itself play ogg, possibly because they don't use this gst.
In other words, that gst is a problem!
Is there anything you can do to use strawberry? Because you can't choose between strawberry and Ungoogle Chromium. I need both working! Any ideas?
