suggestions?? tia, jackc...

I recall from your first message that you were trying to instantiate
hdmi:0,1.  From the above output, that device doesn't exist.  You only
have devices hdmi:0,[3,7,8,9,10].  So, the error message is correct.
For some reason, pipewire? is trying to open an incorrect device.  Do
you have a device hard-coded somewhere in your configuration?  Pipewire
should be able to figure out the correct device to try if it isn't
being told a device to use (I think, no expert on pipewire).
