Must be some config problem in SDL. Can you try the following in a terminal: env SDL_AUDIODRIVER=alsa melt out4.mp4
With pulse running it can't find any device, sure. When the driver is pulse - melt plays movie with sound. But kdenlive still crashes. $ env SDL_AUDIODRIVER=alsa melt ~/out4.mp4 +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ |1=-10| |2= -5| |3= -2| |4= -1| |5= 0| |6= 1| |7= 2| |8= 5| |9= 10| +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +---------------------------------------------------------------------+ | H = back 1 minute, L = forward 1 minute | | h = previous frame, l = next frame | | g = start of clip, j = next clip, k = previous clip | | 0 = restart, q = quit, space = play | +---------------------------------------------------------------------+ [consumer sdl] SDL failed to open audio: No available audio device Current Position: 80 $ env SDL_AUDIODRIVER=pulse melt ~/out4.mp4 +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ |1=-10| |2= -5| |3= -2| |4= -1| |5= 0| |6= 1| |7= 2| |8= 5| |9= 10| +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +---------------------------------------------------------------------+ | H = back 1 minute, L = forward 1 minute | | h = previous frame, l = next frame | | g = start of clip, j = next clip, k = previous clip | | 0 = restart, q = quit, space = play | +---------------------------------------------------------------------+ Current Position: 177 $ env SDL_AUDIODRIVER=pulse kdenlive Removing cache at "/home/username/.cache/kdenlive-thumbs.kcache" 0x477de30 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x477e300 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x39fa180 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x477de30 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x477e300 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x3a39a70 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x39fa180 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x47bb6a0 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x47bbb70 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x3f74720 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x47bb6a0 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x47bbb70 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x3f78fb0 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window. 0x3f74720 void QWindowPrivate::setTopLevelScreen(QScreen*, bool) ( QScreen(0x2b812a0) ): Attempt to set a screen on a child window.

What if you set the SDL audio driver to PulseAudio in Kdenlive ? Go to "Settings" > "Configure Kdenlive" > "Playback" And select PulseAudio as audio driver, then maybe quit and restart Kdenlive
PulseAudio was already set there But I switched off "Use GPU processing..." and it was not crashes until now. So it crashes with movit library. Thank you.
