I have a Mac Mini running macOS 15.5, and I’m experiencing an issue with the headphone output. Whenever I wake the computer from standby, the 3.5 mm headphone jack completely stops working. There is no sound coming from the headphones, and when I check the Settings under the Sound section, the headphone output doesn’t appear at all.
Consequently, audio plays through the Mac Mini’s built-in speakers instead. This problem seems to have started after I updated to version 15.5. The only temporary solution I’ve found so far is to reboot the Mac Mini, which restores the headphone output functionality each time.
However, this is quite inconvenient. I’m wondering if there’s a way to resolve this issue without having to restart the computer every time it wakes up. If anyone has suggestions or has experienced similar problems after the update, I would appreciate your advice.
Thank you for your help.
