Hi guys, since I have briefly used an headphone on my iMac 27" (Retina 5K, 27-inch, Late 2015) it seems with every signal sent to the internal speakers a noise (similar to an out of tune FM radio) is sent with it. Strangely this sound continues even when the original sound already stopped or when I turn off the speakers via keyboard during for example music (music disappears, noise continues). After 5-30 seconds (random) after the signal to the speakers stops the noise disappears.
When using the headphones again I do not hear this noise, which (to me) means it is not in the signal sent. Since the noise also stops after a few seconds its hard for me to imagine the speakers are (suddenly) damaged. I have not uses loud volumes at all anyway.
I have not found any similar issue on different forums, so I hope anybody of this forum has an idea what could cause this annoying error. (I have aso made a recording to clarify, but I see I am not allowed to upload any attachments here..)
macOS is the latest one. I refreshed the RAM (improved the situation a bit it seems, but problem still exists)
Thanks for your help.
