No sound from headphone jack
Mac Pro 2019 - MacPro7,1 - 3.5GHz
Sonoma 14.4
My headphone output quit after using the Microsoft Online speech-to-text converter through VB-Cable,
a virtual sound Input/Output software device.
While troubleshooting this problem I heard an "alert chirp" through my headphones when I switched to the Apple Diagnostics Internet Recovery mode. Hearing that sound made me think that I might not need a new Input/Output board. That is the only sound I have been able to get through my headphones since using
VB-Cable.
I have tried restarts, changing audio settings in Audio/MIDI Setup and the Sound System Settings.
I tried quitting some Core Audio processes in my Activity Monitor.
Any suggestions on what else I can try before paying for a new Input/Output board?
