How to send sound output to Logitech THX speakers

Hello All

How to send sound output to Logitech THX speakers?

I plugged the small RCA jack into the headphone output jack but the sound does not come out?

The Logitech TXH speaker systems has a sub-woofer and two speakers.

The small RCA jack goes to the powered sub-woofer.

However, the sound is not coming out. 

I checked the HP Notebook 15-da0078nr speaker settings but I do not see an options for this type of speaker system.

Thanks for the help in advance.

What is the model of your Logitech THX set ?  For example

               Logitech Z623 2.1 THX Speakers with Subwoofer

Connecting  RCA (as from above set) to headphone combo port on your computer won't work, not enough signal. Does it have Input port ? You have to use this port
