From d0f4a51246e29358783135897909a2da0a165c08 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Fr=C3=A9d=C3=A9ric=20Danis?= Date: Thu, 5 Dec 2024 16:51:59 +0100 Subject: Bluetooth: SCO: Add support for 16 bits transparent voice setting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 29a651451e6c264f58cd9d9a26088e579d17b242 ] The voice setting is used by sco_connect() or sco_conn_defer_accept() after being set by sco_sock_setsockopt(). The PCM part of the voice setting is used for offload mode through PCM chipset port. This commits add support for mSBC 16 bits offloading, i.e. audio data not transported over HCI. The BCM4349B1 supports 16 bits transparent data on its I2S port. If BT_VOICE_TRANSPARENT is used when accepting a SCO connection, this gives only garbage audio while using BT_VOICE_TRANSPARENT_16BIT gives correct audio. This has been tested with connection to iPhone 14 and Samsung S24.
