iMac 27" switches to internal speakers when it wakes up...

I use the headphone jack for my external speakers, and they work well...until the iMac wakes up ...then it reverts to the internal speakers, and the only way I've found to get the headphone jack to recognize my external speakers is to restart the computer...which is not ideal...


anyone hear of this before?? Weird! Any help is appreciated


late-2015 27" i5, 8GB RAM 2TB HDD, Catalina...

First try resetting the iMac's NVRAM, as per > https://support.apple.com/en-us/HT204063


The only other time I've heard that, was from some type of flaky or incompatible third party audio software.
