No sound on Hearthstone running Apple Studio M1 on macOS Monterey. Sound is working everywhere except Hearthstone.
Steps taken to troubleshoot and restore sound.
Battle.net → Preferences → Game Settings → Hearthstone → Reset In-Game Options
Mac OS → System Preferences → Sound → Device for sound output is set to my monitor. Name LG ULTRAWIDE, Type HDMI
Removed Hearthstone and installed Hearthstone
Removed Hearthstone, Removed Battle.net. Rebooted. Installed Battle.net and installed Hearthstone.
Hearthstone since patch 24.0.3
Mac OS Monterey 12.5.1
What are the next steps to try to restore audio on Hearthstone in Apple M1 Studio?
Edit: Solution
Problem solved after updating to Mac OS Monterey 12.6
I had exactly the same problem and finally figured out that it’s caused by audio plugins.
Microsoft Teams installed an audio plugin silently which blocks the audio from all the games. Delete any driver under /Library/Audio/Plug-Ins/HAL and sound comes back after reboot.
