Samsung bdc5500 audio problem

[sbhokray]

Guys....
i recently purchased C5500 which is connected to my LG HT system using optical cable after configuration it worked fine i have upgraded the firmware and since then i am not able to get 5.1 audio from any multi channel audio and video files stored on my USB flash drive the DVD and BD are working fine.
Plz help

Check your audio settings. Is it set to pcm? If then set it to bitstream so that the audio processing is handled by the htib. If that doesn't work then check whether the older firmware is available.

i have already set to bitstream but still no luck plz help me to downgrade the firmware

It seems that downgrading is not possible. Pls read Samsung Blu-Ray Player BD-C5500 Firmware 1015.2 withdrawn? - CNET Samsung Forums

So check whether any new updates are available. Also explore the audio settings in bd player and htib.
