It seems a rare condition, but making it optional could help in two ways.

- As a temporary safe broadcast measure
Programs/contents can still be played while you search for the audio or file error. What could take days if you need external technicians etc

- As a long term solution if your system ...

OK, then it may be an option to make the Overlay player "finish check" optional ?
That could be very usefull in case of audio device troubles.

And/or user notifications for errors related to audio output. Theses errors can be difficult to spot otherwise.


For the root cause, I solved my problem ...

The setup of of the demo PF, for the issue reproduction, is just the default setup. I didn't changed anything.

And in our studio, the routing settings are the defaults ones.
We just have two inputs (one for each live production studio). Studios are used as input in PF, we didn't use ...

I've try to reproduce the issue on my computer. Using a PF demo, i get the exact same issue.

Here is how to reproduce :

- start a playlist
- run an overlay (no specific settings, just playing a wav file)
- disable the play channel (on/off button on the mixer channel)

At that point, the overlay ...

The shell commands only trigger very minor events :
- changing led lights statut in studios (writing values to COM port)
- evaluating the remaining time of the current track and showing remaining time in the countdown window
- sending show infos to RDS etc

My question about audio output is that ...

In the logs I found another Stream stalled error happening in this situation :

- An overlay is playing from 18:00 to 20:00.
- A live show in studio is started manualy a little earlyer 19:54:29.

The current overlay is then stopped with the error "Playback-Stream Stalled".
Is there any possibility ...

Just Stereotools with very few modules. Whole system CPU usage is around 10%.

Thats weird...
Thank you for the details.

To reduce the charge/make it more stable, I've just tryed :
- changing the value of the Lookahead Cache to 256kb (was 64kb)
- removing BPM on load and live BPM calcuations
- excluding PF, music and shows folders from AV.

Will see.
If you think of other ...

For example :
27-09-26 18:56:43: Overlay 'Kool Strings@2026-09-27T18:01:00' Playback-Stream Stalled (Pos1=3339,98933333333, Pos2=3339,98933333333).
27-09-26 18:56:43: Overlay 'Kool Strings@2026-09-27T18:01:00' Playback finished.
-> Here the file is 2h long. It stops after less than one hour.

Hi,

For several months, we have had an intermittent problem with long files played by the Overlay Scheduler.

Pre-recorded shows (1h to 3h, WAV files) scheduled as overlays sometimes stop playing after a random amount of time, between about 20 and 100 minutes. The playlist then resumes. It is not ...
