AAC, MP3 128k+ streams periodically hitch/click/dropout

This occurs across different radio stations that use AAC, and it does not occur with the same streams in other players, like Gradio for example. I know SomaFM offers several 128k AAC radio stations you could test with. I have not tested if this occurs with lower-than-128k bitrate AAC. I have not seen this issue on MP3 or OGG format streams of various bitrates, including high bitrates like 256k.

It sounds like a buffer underrun, but I really don't want to hazard what the problem could be. It seems to be consistent with AAC/AAC+ streams. It happens maybe every few seconds to a few minutes, although if the hangup coincides with something like a snare or drum I might not hear it.

Using 1.1.1-stable flatpak version. Host system Fedora 32, PulseAudio 13.99.1.

Not fixed in 2.0.
