Apps' sound stop working when WotLK Classic opens

Whenever I start WOTLK classic, any other app’s output sound will stop working.
I have done most if not all of the recommended steps to fix it (check drivers, sound settings, disable in-game voice chat, not running the game in administrator mode…).

Here is the last sound.log file content in case it helps:
