From c7dcd064057fb89628c5da55da91dff363b559ca Mon Sep 17 00:00:00 2001 From: Luiz Augusto von Dentz Date: Thu, 11 Apr 2024 09:36:25 -0400 Subject: shared/bap: Make bt_bap_select fallback in case of no channel allocation If channel allocation could not be matched attempt to call .select without a channel allocation as the device might require a different matching algorithm.
