From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> 4db4d5fa1c4f ("shared/vcp: Fix endianness errors") does attempt to fix the endianness of stored volume offset but in the process it broke the notification since the value is no longer stored in the Bluetooth byte order (Little Endian) but instead in the cpu byte order which is then used in the notification as is, to fix this instead of notifying using the stored value it now uses a dedicated variable which does use the value from the request itself. --- src/shared/vcp.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-)
