I have a program that plays audio files. The problem is that in old computers (XP) they are not heard and the quality must be reduced so that they can be heard. I don't know if there will be any method to fix it in the program.
For example, Bit Depth 16 works, but 32 is not heard.
Playwave simply passes a .wav to your sound card. If your sound card can’t play the file it defaults safe to silence. Pick a middle of the road format that works for most situations. For games, 8 bit works fine. For high fidelity recording and playback at higher bit rates you probably want dedicated hardware.
