The first thing you can try, is highlight TRON 2.0 in your game library and press the Menu button > Properties > General > and look for Launch options.

Copy and paste this text into the box under Launch options.

You may need to adjust the number from 30, depending on the result you get. This launch option might help, or it might not at all.

Otherwise, I've seen suggestions to try using Proton Experimental or Proton GE instead of the latest official stable release of Proton from Valve, to help if you experience audio delay in a game.

Proton Experimental should already be available as a choice you can select by forcing the use of a specific version of Proton, as explained here (scroll down or do a search for "Enable Proton for a specific game"): https://gtm.you1.cn/helpsteam/en/faqs/view/7DD4-C618-182E-0E49

Since Proton GE is an unofficial fork of Proton made by the community, with additional fixes, it looks like you'll need to download and install it if you want to try it. There's a tool called ProtonUp-Qt that makes installing Proton GE easier. Search for ProtonUp-Qt on your favorite search engine, and it should show up as the first result. (I'm not linking it directly because Valve now generally blocks links to external sites in message posts.)

After installing Proton GE you should be able to select it the same way as Proton Experimental.
