is optical audio weak? or my tv?

[fatjoez]

I have a problem with my TV & Home Theatre Setup

TV: LG TV LM6410 LED
Home Theatre: Samsung HT-E5550W

Connected as follows
1. TV (optical audio out) -----> Samsung (Optical Audio In)
2. Samsung (HDMI out) -----> TV (HDMI In)

USB hard drive with movies tested as follows.
1. Connect USB to TV, play movie, audio stream to samsung via optical
2. Connect USB to samsung, play movie, video stream to tv via hdmi

Big difference in max volume between the 2 methods.
#2 usb movies from samsung, audio is much louder and more powerful.

Any way to close this gap?

Hey I have same TV. I dont have home theatre. If I want audio output from tv to my creative 4.1 speakers should I buy cable from eBay I.e. digital tosolink to 3.5mm jack which costs around 400 or should I buy digial to analog audio converter with 3.5 mm jack which costs 2.5k
