Capture speaker output
I saw that I can capture microphone and audio files with elements in the Windows.Media.Audio namespace . However, I am looking to capture the speaker output . For example, I click on something and the system hears a beep - I want it to be able to fix.
Is there a way to do this with elements in Windows.Media.Audio
(instead of downgrading in Win32 calls)?

Well, even with "low-level Win32 calls" you can't do looping recording in UWP.
This is traditionally done using WASAPI, but because of the sandboxed execution of Universal Applications, you cannot open capture streams on audio renderers in WASAPI.
In general, if you dive into the COM APIs that have been ported to the UWP, you will notice that there are many limitations.
