Audio playback

I didn’t find a topic about this so that I started a new one.
Aufter trying to play *.wavs in a project and I tried 16 bit that didn’t work.
I decided to try uncompressed Mono 8Bit files (8000, 11025, 16000, 22050, 32000, 44100 and 48000 Hz) which didn’t throw any exceptions but there were only buzzing noises.
Can you provide any information on the wav format/ a converter? Thanks in advance.
