BatWelcome to ProffieOS, type ‘help’ for more info.
Whut? :lay_Kanen.Wav
Battery voltage: 3.96
File tracks/Kanen.wav not found.
Amplifier off.
Unmounting SD Card.
Double check your SD card and the exact spelling and case of this file.
Also make sure it’s formatted correctly, it needs to be a 44khz, 16-bit mono PCM Wav file.
how can i check/ change the format
Most users use Audacity. There’s probably a bunch of YouTube videos on how to use if you search.
i checked and the file is corect,
this is the location
You don’t need to post a screenshot just to prove it to us.
We trust you.
Oh oke sorry
i compared it with other file but some see anything strange
It is spelled wrong 
. You put Kanen.wav in your config so your SD needs the files named Kanen.wav not Kanan.wav or you need to fix your config a reupload.
still nothing
what did you do? and what does Serial Monitor say?
I changed the name of the .wam file to to correct one.
Still get confused with serial monitor do i type play or play_Kanen or with .wav
“play_track”
And i need to be on the kanen font right?
Yes, if that’s the one not working
channels: 2 rate: 48000 bits: 16
Unsupported rate.
Amplifier off.
Unmounting SD Card.
This happend when i typed play_track on the corect
font
So your file is not formatted correctly go back to post about format
how ir says this,
Not RIFF WAVE.
Amplifier off.
Unmounting SD Card.
Like Fett is saying, your best bet is to take the sound file that is a problem, open it in audacity, then save it with the right settings:
It’s fairly easy with audacity and something most users come across. I think it’s at least in part because font makers create board specific packages, and they may get mixed up. Once you do it once you can clean up sound files as you need to.
Also, please remove the screenshot. It takes up a lot of server memory and this one isn’t necessary.
