libsndfile: Can't open anything.

I tried to use paplay to test something but that failed:

LibreELEC:~ # paplay test_mono_44100Hz_8bit_PCM.wav
sndfile: Bad parameter passed to function sf_command.
Failed to determine sample specification from file.

So I collected some wav files around the net and tested them: Same result.

This is with OpenELEC 7.0.1 on a RPi 3.

I readed that, so it would be much better if you tell me what's missing. Anyhow, here every single requested information:

• Raspberri Pi 3
• 7.0.1
• There is no log
• Try to play any file with paplay or any other tool utilizing libsndfile

• No
• video
• issue

• Paspberry Pi 3
• 10858744
• Include lspci into LibreELEC and I'll give you the output...
• This is no USB issue. But just in case: 10858745
