Guys i need help setting up a karaoke system in my home, not so sure what I need

Lets start with what I have:
1- Soundbar (Samsung Q930D)
2- LG Smart TV (quite recent model, not sure the exact model number)
3- TV Box (SVI 10s)
4- Wireless Mic (https://shopee.com.my/-24H-Ship-SHUER-302-Wireless-Microphone-Karaoke-UHF-Receiver-Rechargeable-Wireless-Microphone-For-Speaker-HomeKTV-i.864585302.24275176100)


So I was stupid thinking can just plug and play the wireless Mic into my TV box and play... Turns out its not that straightforward haha


Currently my setup looks like this

TV Box -> TV -> SoundBar (via HDMI eARC)

The mic I have is transmitting radio signal and has a 3.5mm jack. My TV and TV box both have something call Toslink input. However, I learned that there is no way to easily convert mic (analog output) to digital (toslink input). Went to lowyat and they told me I might need a V8 soundcard since my soundbar doesnt have other input options.

Can anyone show me the way as I'm not sure what are my options here (without buying another speaker system).

wow nice

handsome can share the link to buy?
