[pulseaudio-discuss] [PATCH v8 06/12] bluetooth: Set correct endianity of audio samples for SBC codec

[Pali Rohár]

Pulseaudio SBC codec defines that audio samples are in PA_SAMPLE_S16LE
format which is little endian. But libsbc library expects audio samples by
default in host endianity which is big endian on big endian system. So SBC
support on big endian system is broken. To fix this problem tell libsbc
library that audio samples are in little endian to match PA_SIMPLE_S16LE
sample format.
