How can I resolve HomePod 2 won't factory reset, plays music randomly at high volume, and Siri talks by itself.

The problem started a few months ago making some strange tapping noises and Siri keeps talking by itself and then plays music even though I deleted Apple Music from all my apple devices and that the OS version is 18.4 and I was able to do factory reset so I tried so many times doing factory reset but the problem hasn't resolved so I ended up installing beta version and did factory reset on both my Apple TV and both HomePods then it worked for a days with out the problems I mentioned earlier after it started again so I tried to install HomePod os 18.5 beta and the problem still continued so I was about to throw these **** things to wall but then I taught may be I should use these with Mac mini speakers so I have factory reseted again and freshly installed with my Mac mini and from then it got worse now one HomePod is able to reset but in completely different way not like when it was on 18.4 where the red spinning light thing happens and Siri will say about resetting. Now in 18.5 it looks like the process changed no more Siri talking no more red light spinning just resets and pops up like new HomePod when you I put my iPhone near to the HomePod. This is happening with only one HomePod and the other one is stuck on a name which I gave previously and it keeps showing on airplay but cannot be found on any apple device HOME APP and factory reset is not working.

So im afraid of this HomePods because they might play music with full volume at midnight while everyone is sleeping so Im disconnecting the power cables everyday and left them like two BRICKS in my living room they are out of warranty and I dont know what to do with them so please Apple help me or I will make **** video of this craziness and post in threads and all social media platforms may someone will help me!!!
