Alsasink not playing BE PCM in LE Machine & vice versa

Submitted by vijay

Incase of LE machine alsasink is not listing the BE format even if Alsa deivce has the capability to play BE PCM.

Root casuse:
Check added in ext/alsa/gstalsa.c function "format_supported"

if (GST_AUDIO_FORMAT_INFO_ENDIANNESS (finfo) != endianness
&& GST_AUDIO_FORMAT_INFO_ENDIANNESS (finfo) != 0)

Steps to verify:
Play any BE PCM/WAV file in LE machine

Working on Fix.

Thank you
