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? 

no,  it's a F34 workstation. one of my setup chores is to get audio working with my LGTV.
i had pulseaudio running on my last install so  hw  works.

this is probably my screwup, but i have been trying to Not futz with the released bits.


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).

me either, but i like what i read about PW so this is a good challenge

i'd like to get to the bottom of this no audio state.

Q: do you why there doesnt seem to be systemctl files(start,stop,status) for pipewire, pipewire-pulse, pipewire-media-session ?

also i want to track this non-existent file.

thank you very much for these insights.
