Print the number of PulseAudio input channels when in verbose mode

[Calinou]

This is useful information to have for troubleshooting, and it's said to sidestep a possible race condition issue that breaks microphone recording on Linux.

Other verbose messages were tweaked to refer to output explicitly (as opposed to input).

See #33184.

@enorrmann @mgschwan To confirm whether this comment is still correct, can you test this editor build which is 3.4-stable with this PR cherry-picked on top? https://0x0.st/-5vV.zip

Try running the Mic Record demo with it, with and without Verbose Stdout enabled in the Project Settings.

Thanks in advance 🙂

Verbose Stdout

for me the issue remans, in part, the recording part works fine, but when I press Play, the app "hangs" for a couple of minutes, then it plays the sound, with lots of underruns
