iMac Music app no longer streams to HomePod independently

Having recently updated my iMac to Tahoe 26.2, I discovered that Music no longer allows me to choose to port to my HomePod. Is that gone for good, or am I missing something? My only option apears to be to send all audio output to the HomePod (ie, my. phone ringing through to the computer, for example). I enjoyed the ability to have music from one source while having the audio for my phone on the iMac.
