Hi everyone,
I reinstall my late 2013 iMac, because I had some problems with my network drives and it work now for 6 year.
I did a clean install (erased my drive) and installed directly to the lates supported osx (catalina 10.15.7).
Everything works fine except if the iMac goes into sleep mode after waking it up I don't have any audio. I need to restart the iMac so I have audio working again. The other option is to unplug and replug in my speakers (headphone jack).
I found a couple of terminal commands but non of them worked for me.
Before I reinstalled my system I didn't had any issue with the audio (same setup), but I'm not sure if I had the lates osx catalina update installed. Also the startup chime changed.
Can anyone help me with my issue?
Thanks
Regards
edit: pram and smc reset didn't worked. If I play music and the iMac goes into the sleeping mode it continues playing the music, but when I'm going to wake the iMac up, it stops playing the music. after disconnecting the speaker (headphone jack) it works again.
edit2: problem found ... after "sleep mode" the iMac wants to use my external monitor (connected via displayport) which has also an audio jack as an audio device. after changing it in the sound option to "headphone" again it work. Now my question is, how can I say that my internal audio jack is the primary used one?
