That doesn't sound promising. The qt6-webengine build succeeded, but  
this symbol is missing... :(
As the port only has the audio options, it's not some direct influence  
which is causing it, but some indirect dependency on something in the  
dependecy chain I would assume.

I had a look at the faq and explanation of the sandbox at  
chromium.googlesource.com, but I didn't see any low level stuff which  
could help to identify why it isn't in the lib.

Bye,
Alexander.
