Subject: [PATCH 0/1] test: simple-endpoint: Add support for LDAC

This patch adds support for LDAC to the simple endpoint script.

It has been tested with the LDAC plugins in gstreamer which recently got
merged and can be found in the two merge requests below.
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1621
https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/757

For testing this with upstream, gst-build would be required.
