No Recognition.

Hi community! I'm having an issue with getting my Lenovo Legion Pro 5 (with RTX 3070 ti) to pass sound to either my Sony Blu-ray home theater (with arc) or to my new Samsung Q990C soundbar. When plugged to my HT my laptop simply does not recognize the device and I can only plug it to the HDMI...

UPDATE: I may have just screwed myself. I found out how to delete the volume RAID and now my computer can't find my bootable hard drive... Only way I can think to fix it would be to make another volume but this one doesn't say I can keep my data which would suck as I don't think I have windows...
