Audio stuttering with pulseaudio , debug reports pulse pulsesink.c:702 ...Got underflow

I am playing a stream with pulseaudio like this:

gst-launch-1.0 playbin -v --gst-fatal-warnings --gst-debug-level=4 uri=https://edge214.rcs-rds.ro/V4-3036850-beb1b900f18955083bcd7cb147a0bba4-1495840202-0-1591903019-4-digi24/digi24/digi24-abr.m3u8

Unfortunately the stream has some location restrictions so you might not be able to get it to play. From time to time, randomly I have 1-2 seconds when the audio is not playing but it recovers. At exactly that time the debug reports error in the console :

0:04:32.827319214 14791 0x55a32c1a1b30 WARN pulse pulsesink.c:702:gst_pulsering_stream_underflow_cb: Got underflow

It then recovers and plays normally until it happens again.

I've attached the full output from the console.

I am using Manjaro Linux with versions:

gstreamer: 1.16.2-2 pulseaudio: 13.0-3

I can probably work around this by using ALSA output but I still think it should work. Playing the same stream with mplayer ( or mpv ) gstLog.txtworks without any audio interruptions.
