Subject: [PATCH 1/3] audio/transport: seprate a2dp and bap transport to update volume
Date: Sat, 1 Oct 2022 00:19:52 +0530 [thread overview]
Message-ID: <20220930184954.108937-1-sathish.narasimman@intel.com> (raw)
Identify BAP and a2dp transport to update the transport volume.
Also add properties volume for bap_transport.
