white noise unexpected sound when playing the files

[cyrax50000]

Hello!

Thanks for this interesting library. It's really compact and for sure can be used in many projects.
I had some strange problem when trying to run the examples on my old tv box, an allwinner a10 armhf system.
The example1 works fine there.
examples 2 and 3 do play the notes, but also some quite loud white noise plays in the background.
I have also tried to use the tinysoundfont implementation from esp8266audio and got a similar problem there. A background whooshing sound goes together with every note played.
On a regular x86_64 system it works perfectly.
Any hints to solve this? thanks again...

You may note that example1 outputs in signed integer 16 bit, while examples 2 and 3 output in floating point 32 bit, which your device may not handle properly.

Hello,
Thanks for the reply. You were right, I have used tsf_render_short instead of float and now it's working.
Have you seen the ESP library? There, they seem to be using some modified version of tsf_render_short already, so I can't see why a similar problem happens.
