Hello. I am building my home theater system.

Right now, I connect my pc to Sound Blaster GC7 through usb and connect GC7 to Sonos Beam Gen 2 through the Optical to HDMI converter comes with the beam.

I set the Sound Blaster GC7 output to 7.1 surround, not virtual 7.1. 

Why in my app, the audio in still show Stereo PCM 2.0?

 

Thank you

I don’t know much about the SoundBlaster GC7, personally speaking, but I did come across these links which perhaps may assist…

Optical ports do not support uncompressed multichannel 7.1 LPCM - that’s undoubtedly why you’re getting stereo only - you would need to send that audio codec over an HDMI-eARC connection.

The best output you can hope for over the optical link will be compressed Dolby Digital 5.1/or DTS 5.1 audio.
