Corresponding commit implements functionality on kernel side. 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. This also adds a test to checks that BT_VOICE_TRANSPARENT_16BIT voice settings can be set and get using [set|get]sockopt(). v1 -> v2: Add test to tools/sco-tester Frédéric Danis (2): lib: Add constant for 16 bits transparent voice setting sco-tester: Add test for BT_VOICE_TRANSPARENT_16BIT constant lib/bluetooth.h | 1 + tools/sco-tester.c | 28 ++++++++++++++++++++++++++++ 2 files changed, 29 insertions(+)
