Philip Using a Valve Index. Downloaded the 6k h.265 11.54GB file.
Playing the downloaded file, the sound is just extremely poor quality. I mean "recorded through a walkie-talkie" sound quality, and for most of the video it is about twice as loud through the left channel as the right channel. It's not just "oh lame, the sound quality is bad", it's actually poor enough to ruin the experience.
Playing the streaming version: same thing. Both streaming with the "spatial audio" toggle on & off produced the same issues with sound-quality as above.
This is the first time this specific audio issue has come up in hundreds of hours streaming and playing downloaded scenes from SLR, so no idea. Every other scene from SLR still sounds as it always did.
Could very well be a one-off issue for some reason, so if it sounds good to you might not be worth chasing. Hope this isn't the new norm though for non-Quest 2 users.
