Laptop and ST300 connection & 5.1ch output problem

Hello 🙂

I have ST300/AM300/VI300 connected into my Windows 10 Laptop via HDMI.

The audio driver will connect to Siliconimage, not BoseLS.

In addition, only 2ch output is done, not 5.1ch output.

What is the problem?
How can I solve it?

I must make 5.1ch output via HDMI.(Not optical connect)
I am waiting for your help. Thank you!

Hi young hyun, kim


Thanks for joining the community!  Sorry to hear about the setup issues, but I'd be glad to help!


There may be some audio/video drivers that could be available to help, I'd recommend checking your PC manufacturer's website.


The second issue could be that the HDMI port is linked to your motherboard vs a dedicated graphics card.  Some of these are limited to 2 channel output only.  


If you have an further questions, I would recommend contacting your PC manufacturer as they would be best equipped with changing some advanced audio settings within your machine.
