[AE] fixed: allow ALSA passthrough with non-native data format

The ALSA sink currently only tries SND_PCM_FORMAT_S16 for passthrough.
However, the non-native endianness format is not tried. The most common
case when this is needed is big-endian systems that commonly have an
ALSA device that still takes in S16_LE.

Fix that by trying both formats for passthrough if SND_PCM_FORMAT_S16
