Sound made when you say "Hey Siri" isn't the original 2 dings. Now it's a muffled LOOOOWWW bump sound

Right after the ios 15.x update siri sound is nothing like it's been since it was invented. I searched everywhere and all I find is "siri voice" is muffled, or it doesn't respond.

Mine went from the audible double ding sound to a single low muffled almost bump sound???

I went through (shut down. Restart, change voice, change language, reset everything, except factory default, which I should NOT have to do after a simple update).

This is so frustrating, I have just about stopped using Siri! If I had the cash, I'd toss this off a cliff into the ocean and get a new one at this point, that's how frustrated I am at the 10,000 attempts to get it back to the original (normal volume so you CAN hear it, sound).

Any help would be very, very much appreciated.

Thanks
