Raspberry Pi4 - send own audio output (speaker output) #74
Comments
ok, i cannot get it to work on PI4. works with other versions PiFmRSD, or with FM_Transmitter, but with this one is not :( pacmd load-module module-pipe-sink file=/tmp/pulse.fifo Let me know if this works. there is something missing here, could it be: ? Anyway, thank you for your work. !!! |
Now i get an errror when trying to start the station: |
It has been a long day, so I may well be wrong, but it doesn't look like
you are piping anything to the input, but you are calling stdin.
Maybe you could create some ALSA virtual sound devices, one playing back
the movie soundtrack and the other used as a capture device...but I am not
so sure if PiFmAdv works on a Pi4 though.

Easiest solution for piping Pulseaudio is using |
Hello, is it possible to broadcast my own Audio Output ?
So I have Raspi4 which is connected to a Projector.
I project the a Movie on the neighbours house, and also the other neighbours are watching, and i tought that i can send the sound of the movie thru FM Radio, so the other neighbours can also hear the sound, not only the Image.
Do you know how i could send the Audio from the movie ? I'm usind Kodi as a media player.
Thank you
