Just for me to understand what you're trying to achieve: what do you mean exactly with pipe to a file?

If you want to access the audio files that the app downloads, you could simply get them from the folder that they're downloaded to.  This is ~/.local/share/KDE/kasts/enclosures if you haven't customized the path.

Or do you mean that you want to pipe the audio to another program?  In that case, most audio backends allow to re-route audio to e.g. pipes.

Hi .. thanks for answer.
It is the second option you mention there and i think you might be right... I could make pulseaudio pipe to file but it would be a bit more work if for example i have a setup with snapcast and just want to cast the Kasts sound out to snapcast speaker system and not my laptop speakers

hmm hmmm you might be totaly right there ... but then i must have a way in kasts to choose audio output device ?? if i want to switch between audio out in my laptop speakers or to the sink that sends to file?

He he... i think i get it now ... sorry i am not used to sound things....

I see now that i should be able to do this in kde thru the normal pavucontrol-qt ... as long as i in someway can get my sink(output) to file from pulseaudio to show ut there as an output device .... i just have to readup more on this and how it is suppose to be done ... sorry for creating spam in your bug report list :D

You can close this ticket

I'm also using snapcast myself for other purposes.  AFAIK, it's possible to pipe all pulseaudio audio directly to snapcast.  Possibly you could set up a dedicated output sink that will directly feed to snapcast.  That way you would avoid the detour through named pipes.

ok ... thanks now i know more how to solve it ...

I'll close now (as you suggested).
I hope you manage to set this up.
