Logitech 5.1 center speaker not working.

Hi. I have a problem for a long time with my 5.1 Logitech surround system. My center speaker is not working (physically yes). I have ASUS Maximus Hero VII motherboard.
Plugged jack layout: orange: subwoofer/center channel, black: rear speakers, lime: front speakers. I have no idea what is wrong. E.g.: while I'm watching a film, I can hear every effect clear, but I can't the dialogs, which is the center speaker's task i think. I'm using VLC the config is correct in the program.

Specify model of Logitech 5.1 speakers. Assuming then the Subwoofer is working then ? Making sure jacks are secure on back of the PC and the speaker unit. Not sure if these speakers have wires that detach or not also, if so make sure those are secured.

Shows your board to have up to 7.1 surround sound. Did you check your Realtek Audio Manager settings besides the one in the VLC Player ? Do you have latest Realtek Drivers installed ? Movie on a bought disc, did or do all movies do the same ?

Here is your board

Try checking it also from Sound in the Control Panel, the Playback tab select the Speakers, they should be the default device according to the Sound device used in your case integrated sound device(Realtek). Highlight that device select Configure check to see it should list Stereo and 5.1 surround, highlight 5.1 and Test it, see if it reproduces sound in center channel. Probably do this with Realtek Software to.
Other causes bad speaker or bad wires.

 

I don't have bad wiring. I have Logitech X-530.

Have you tried any of the suggestions ?? Have you moved the wiring when playing movies to know for sure as this was only a possible cause not a positive cause or even the wires that go from sub to the PC. Older model Logitech i had the X-540 once myself similar one.
Is the movies you are playing 5.1 ?

Yes, I've put my earphone directly to my center/sub jack on the motherboard and it worked in the driver sound test. So it's not the motherboard's problem.

yes

Tried all of the suggestions from my first post # 2 still get no sound from center channel speaker and sure audio part is 5.1 ?

The output works and the center speaker is works. but between them something is not correct.

Read your first post said for long time center speaker is not working. Since same connector runs the sub to, does that work because you never answered ? Is it only with movies the center does not work ? Did you test it with Sound properties as asked in control panel or and even your sound device i believe Realtek audio manager ?

My sub is working correctly with test. The center does not working with test and movies.
