   I too have had trouble with a Pi4 losing sound but up to now I've   
   blamed it on the HDMI monitor, since power cycling the monitor   
   brought back the sound. Tried that in the present instance with   
   the Pi5 but it didn't help.   
      
   Next I tried a warm reboot, but the machine got stuck with a black   
   screen, though I think it was coming up to multi-user. It would   
   answer a ping and refuse an ssh connection, per the configuration.   
      
   Eventually I did a power cycle and played with audio under rapsi-   
   config, now sound works and at least a couple of warm reboots were   
   successful as well. At the moment, a Chromium browser tab is stuck   
   and won't scroll, but four other tabs behave normally.   
      
   I guess maybe it's just Bookworm/Wayland being buggy.   
      
   Thanks for writing,
