pulseaudio: Initialize fragsize to fix mic recording fragsize wasn't initialized, and it is used for recording. If the value was 0 or -1, pulseaudio configures it itself. But sometimes we can get a random (and large) value that makes pulseaudio give us large sample at a very low frequency. https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/blob/master/src/pulse/def.h#L453 https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/blob/v13.0/src/pulsecore/protocol-native.c#L409
