<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">bluetooth: ldac: Use format as FLOAT32LE
LDAC encoder already supports S16, S24, S32 and F32LE. Using FLOAT32LE
for the sample format would avoid the additional call for conversion to
pa_sconv_s32le_from_float32ne. perf tool shows this as being the function
called frequently after encode. So, just avoid this by using sample format
as F32LE.
