Thanks for reporting.

Took a look at the package content and changes. Looks like padsp was present in Ubuntu 23.10 [1] and then removed in 24.04 [2]. Which means something happened between versions
1:16.1+dfsg1-2ubuntu4 [3]
1:16.1+dfsg1-2ubuntu10 [4]

Checking the changelog between these two versions led me to https://launchpad.net/ubuntu/+source/pulseaudio/1:16.1+dfsg1-2ubuntu8 which disabled padsp. though is short on details why. So there might be other issues which should be resolved before it can be re-enabled.

Regardless, now that it is disabled, looks like additionally:
* the package still contains bash completions for the binary even though it isn't included [2}
* the database for command-not-found doesn't seem to have been updated after the binary was removed. It probably should to reflect which binaries exists and are offered by the package.

Well whatever, the situation results in:
```
$ padsp
Command 'padsp' not found, but can be installed with:
sudo apt install pulseaudio-utils
```
but `pulseaudio-utils` doesn't have `padsp`.

if you check the diff of that package update the patch header has the explanation

but yes we should remove the corresponding bash completion entry and update command-not-found
