--- Comment #1 from Jarno van der Kolk <ja...@jarno.ca> ---
Apologies if this is a different bug but it sounds very similar to what I am
experiencing so I believe it may be caused by the same thing.

Every month, I load all video clips from my bike camera into Kdenlive (~10
hours worth) and play each one at 10x speed to search for notable events. The
audio playback sometimes drops when I switch from previewing one clip to the
next.

I've been keeping an eye on the playback device for applications in the Plasma
volume widget and I notice it switches to "no applications playing or recording
sound" when this happens. Like Daryl, only a restart of Kdenlive fixes this.

I think the action of simply selecting a clip (like I do when previewing and
what Daryl does when dragging/dropping) sometimes causes the playback device to
drop and Kdenlive seems unable to recover from that.

In fact, I can reproduce this by loading a project with a few video clips and
rapidly selecting one and then the other several times.

I am also on Arch Linux with Kdenlive 24.12.2.

>From the log on the console:

<code>

ACTION:  "C&liptaken configureren…"  =  ""

The important thing here being (I think!):
MLT: "[consumer sdl2_audio ] SDL failed to open audio"
