If the Sony micro jack in is for a microphone you may not get the results you're looking for. You may want to try the following Belkin adapter:
I have a samsung series 5 full HD tv (LA32C530F1R) which has below audio output (apart from its inbuilt speakers)
1. A mini jack audio out.
2. Digital audio out (optical)
My sony Home Theater (
DAV-DZ640K) has below audio inputs .
1. mini jack audio in
2. RCA audio in
3. Audio Return Channel (HDMI)
The home theater works fine when played using DVD or USB .But
when I connect my tv to home theater, using RCA or mini jack ,the sound quality degrades.(feels no surround sound )and my tv's HDMI version is 1.3 (so no Audio Return Channel )
So what is the best to get better TV audio out of my home theater
