I have a modest 42" Samsung TV and have recently bought a Sony Home Theatre (BDV-E2100). Both devices are connected to a desktop. On the HT, I noticed there are two microphone ports so I dream of setting up my own karaoke system.

I have loads of KTV version MTVs that can be played using VLC player and switching audio channels to mute vocals, but I just can't seem to make it work for the HT. When I plug in a mic, it says NOT.USE that probably means karaoke is not supported when audio input is from a computer. Something that the salesman did not tell me when I made the purchase.

With this setup, how can I proceed to realize my dream of having a home karaoke set? I am OK to spend more to finish the setup, and something like an Android KTV box thing comes to mind.

Any pros have any suggestions or recommendations?

Thanks in advance.

Hmm OK.

I probably need an amplifier to go along with this.

I have also been searching around for an Android box that can also has KTV functions. Can you tell me if I'm too ambitious?

Don't think android has this function as well

You are my hero. Is it this one? http://www.lelong.com.my/xiaomi-tv-mibox-b...7-01-Sale-I.htm

Shinchan,

What app are you using for the Karaoke?

Thanks,

I downloaded the manual but it has no mic input. Getting confused    I want to find the spec

Sorry what is Line Input from PC? ... Do you mean Audio Input?

If I remove the Yellow/White-to-USB cable and use BD-DVD/USB/Bluetooth mode, the mic can work.

But the mic cannot work when the audio is coming from PC.

Please refer to the attachment for an illustration. It is just a simple diagram of how my devices are connected.

The connection between my PC and HT is via a USB to Audio cable. One end is a USB jack, and the other end has White and Red wire. No Yellow, thus no Audio.

My PC does not have a HDMI port, so I could only use a VGA cable. It connects to the TV.

The HT is connected to the TV via a HDMI port.

So basically the Karaoke function on the HT only works for BD-DVD, USB and Bluetooth. It does not work with the USB to Audio Cable. When I plug it in, the console on HT says "NOT.USE". I can watch movies on the TV using the PC for selection and HT for audio.

I also tried plugging the mic directly to the PC, no good.

Ohh! I'm forgetting something here  . You still need music sound from PC, not just your beautiful voice    Shame on me. Let me see what other option I can suggest 

Hey! Since your BDV-E2100 is DLNA capable devices, why not fully utilize that. You can let your HT discover the files from you hard drive and controlled it directly from the HT instead of separately from PC. Then no need to use stereo Line input

Based on the info provided in the manual, I think the karaoke function will only work when the video files are played from the player itself. Most likely external sources are not supported.

DLNA is just like network file sharing (not Bluetooth). If you have a DLNA server running (windows 7 and above have built-in), your player should be able to access the files.

But if you need karaoke functionality (ie queue songs, search singer, etc), then the USB drive and DLNA might not be able to fulfill your requirement. You'll need a dedicated karaoke machine for that.
