+Subject: [PATCH] utils: add a gstreamer helper application for interconnection
+ with pipewire
+
+Unfortunately, the bluez-alsa PCM plugin does not work correctly
+when it is used through pipewire (or gstreamer, or anywhere really...).
+
+Thanfully, the bluez-alsa PCM plugin is only a simple client that
+reads/writes on a file descriptor that was opened by bluealsa.
+This allows us to use bluealsa without the PCM plugin, just like it
+is done in the aplay.c util.
+
+This one uses GStreamer to implement the plumbing between pipewire
+and the file descriptor. On the reading side we are also doing some
+tricks to ensure a smooth stream, which is not the case for the
+stream that is coming out of bluealsa.
+
+This helper is implemented as a patch to bluez-alsa so that it can
+use its internal private API. In the future this needs some re-thinking.
+
+Upstream-Status: Inappropriate
