Symptoms

2 regressions.

Regression #1:

• Proton: 1761241153 experimental-10.0-20251023: all the speech samples are completely missing, only music and effects can be heard
• Proton: 1757428112 proton-10.0-2e to 1731348819 proton-7.0-6f: all the speech samples are played not upto the very end (the last 0.3s-0.7s are always cut, depends on the proton version. For example, proton-10.0-2e cuts the words "military operations are underway" to "military operations are under" and "entering combat mode" to "entering combat", while proton-7.0-6f cuts them to "military operat" and "enter")
• Proton: 1655928814 proton-6.3-8g: all the speech samples are played properly

Regression #2:

• Proton: 1761241153 experimental-10.0-20251023 to 1731348819 proton-7.0-6f: regardless of whether Steam Input is enabled or not, the ingame cursor control is broken, if you point at something in menu and press "A" - the cursor jumps top-right and the menu press doesn't get registered (touch screen controls work fine)
• Proton: 1655928814 proton-6.3-8g: ingame cursor control works properly
