I wondered why the PS5 didn’t have optical out when the PS3 did, then thinking back on it, I probably never owned content/speakers that were good enough to really tell the difference. I had routed the PS3 audio to a receiver with 5.1 surround, and video to a projector via HDMI. Then just played media from an external/had a dual boot to yellowdog Linux at the time. Was fun for young me
