Best setup for sound latency

I mostly play Rhythm games (Stepmania Pump It Up). So I bought 7.2 Sony HT-M77 for better experience when playing.
Since everything is synced to the sound. I want sound-latency to be as low as possible. Sound quality does not matter.
The played-music-files that the program use are in .mp3 format

And these are the 2 setups I've been using with the Home Theater System:
Setup1: HDMI cable from TV's HDMI port to DVI port on graphic card, another HDMI cable from HDMI port on HT-M77's amp to graphic card's HDMI port.

Setup2: HDMI cable from TV's HDMI port to graphic card's HDMI port, analog cable (green to white/red) from 3.5mm green jack on mobo to HT-M77's audio port.

Setup3: may consider to buy a good sound card instead of the one on mobo.

For now, it seems that setup 2 has less sound latency (not sure). But is it possible to reduce the latency even more? In any other ways ?

(FYI, I've done all the possible SOFTWARE recommended tweaks to sounds like DPC tweaks, turn off enhancements, switch to 44.1khz, ect... so this topic itself is HARDWARE related, actually)

My computer spec:
TV: Samsung J6200 60" - used for display only, not sound.
Sound system: Sony HT-M77 2450W 7.2
MOBO: Gigabyte B85M-D3H
CPU: Intel i5-4460
Graphic card: Asus Strix GTX 950
RAM: 8GB 9-9-9-24
SSD: Kingston 240GB

Thanks in advance!

To confirm my own question, using analog is somehow better than HDMI latency-wise
I bought Creative Sound Blaster Z and it sounds a little clearer (though the lantency is about the same as onboard sound) - still I'm keeping the sound card.
But I guess it wouldn't be a matter if you use HDMI with a good amp which has a good DAC

It seems that I've found the answer myself :D I'll leave the answer and the link here in case you find it's interesting to read

So what did your problem end up being?
You said that you did all software side tweaks, so not sure what it could have been.....
I recommended a 144hz monitor as you made no mention of it in your original post, instead stating that you used a TV. :)

My solution is to use RCA cables (analog) for sound and HDMI for display. And to buy a good sound card (since the audio source from the onboard sound does not sound as good - it's Realtek 892 chip). I'll comment here again once I (actually - we) finish testing it.
And yeah :D for hardware-wise, 144hz monitor surely beats the best TV at the moment, in term of display-lag
