Hello James,

For the patch, I've applied, but after doing a few changes. See below.

I pushed a separate patch that changes that menuconfig to a normal
config option, since we only use menuconfig for packages that really
have a lot of sub-options.

This is now also needed because the alsa-lib select, so I've updated
the comment.

This comment needs to be further down, otherwise kconfig is not smart
enough to "indent"  the sub-option about gstreamer to be "under" the
main pipewire option.

Should have been a "config".

We prefer to enclose in an if ... endif block the sub-options of a
package.

The corresponding Config.in comment was missing.

I've added gstreamer1 in this list of dependencies, to match the
selects done in the Config.in file, even though I agree that
technically speaking, gst1-plugins-base anyway depends on gstreamer1.

Applied with those changes. Thanks!
