I have a Q990D and a Sony TV with eARC port and I have a few questions

1). Should I plug ps5 directly to the TV or via passthrough for optimal sound quality?

2). what's the best audio output settings to use in the PS5? Linear PCM, Dolby Atmos, Dolby Digital etc.

3). Should I set it to sound bar or AV receiver. Not sure if you get full surround with the sound bar option. And if Av receiver is selected should I choose 5.1 or 7.1 for the best surround?

All very confusing some help will be appreciated.
