Description:
The current virtualbox PKGBUILD may build and statically link in an in-tree copy of libvorbis (@ $srcdir/src/libs/libvorbis-1.3.7) within a clean chroot. This library is used for video capture.
VirtualBox 7 had switched from libopus to libvorbis and with 7.0.2, the configure script at the time still had no ability to identify the available system lib using pkgconfig. However, this was recently implemented with revision 97397 in the SVN trunk ( https://www.virtualbox.org/changeset/97397/vbox ), and should be used with the next upstream version bump (e.g. 7.0.3) by specifying libvorbis as a runtime dependency.

Additional info:
As of 7.0.2-2, the symbol table for a VirtualBox component contains several libvorbis symbols, indicating static linking:

$ nm -gDC /usr/lib/virtualbox/components/VBoxC.so | grep vorbis

000000000031c470 T vorbis_analysis_blockout

P.S. I realize now that this is more of a general gripe rather than a bug after submitting it, as it lies in the upstream 7.0.2 tar, though it seems I can't change the task details now. Apologies!

7.0.4 is out now and it includes the linked changeset. However, things seem to have changed as I cannot find any evidence of the in-tree copies of libvorbis and libogg being compiled at all. Because of this, I suspect audio recording does not work in our 7.0.4 build. Can you confirm?

If audio recording is supposed to work then we now probably need to pass `--enable-libvorbis' and `--enable-libogg' to configure and adjust the deps.

I can confirm that there is no audio option when enabling recordings in a virtual machine with the 7.0.4 build. The above linked changeset appears to not only removed libopus references but also disabled audio recording by default.
