+Decode A2DP codec capability hex strings
+----------------------------------------
+
+:Date: September 2024
+:Manual section: 1
+:Manual group: General Commands Manual
+:Version: $VERSION$
+
+SYNOPSIS
+========
+
+**a2dpconf** [*OPTION*]... <[*CODEC*:]*CONFIG*>...
+
+DESCRIPTION
+===========
+
+**a2dpconf** presents the fields of the given A2DP codec *CONFIG* in a
+human-readable format. *CODEC* is the name of the relevant codec, and *CONFIG*
+is the hexadecimal encoding of the configuration or capabilities binary "blob"
+as reported by tools such as ``bluealsactl(1)`` or the debug output of
+``bluealsad(8)``.
+(see `EXAMPLES`_ below).
+
+OPTIONS
+=======
+
+-h, --help
+    Print this help and exit.
+
+-V, --version
+    Print version and exit.
+
+-x, --auto-detect
+    Try to auto-detect the codec. If the name of the codec associated with the
+    configuration string is not known, then give this option and the
+    configuration string without the codec name prefix. The output is then a
+    list of all possible known codec configurations for which the given string
+    is valid.
+
+EXAMPLES
+========

+    $ a2dpconf sbc:ffff0235
+    SBC <hex:ffff0235> {
+      sampling-frequency:4 = 48000 44100 32000 16000
