Crackly when seeking with ma_sound_seek_to_pcm_frame() #449

I am using the easy setup of miniaudio and calling my own play() quite a lot, quite fast but not every frame, only when a new thing is displayed on screen. inside my play() I have ma_sound_seek_to_pcm_frame(sound, 0); it results in the correct sound being repeated but it seems to crackle. Just playing the sound once normally without ma_sound_seek_to_pcm_frame does not produce a crackle.

@quetzalsly When this happens, is it just a one-off glitch for each seek, or is it like a persistent crackle that lasts the length of the sound? What flags are you using when you initialize your sound? If you're not already, are you able to try with MA_SOUND_FLAG_DECODE and let me know how that changes it, if at all?

I am actually already using that decode flag, to me it sounds like the crackle is at the very start of the series of sounds. I tried to simply make a sound[10] array and play each one only if its not already playing, resulting in something like what I needed, but I would prefer to do it with resetting the buffer on a single sound. Also this is happening on very small sounds that are like 1 sec and under like little beeps that are meant to make a beeping signal.

Are you able to give the dev branch a try? I had a report about a crash with ma_sound_seek_to_pcm_frame() which I've fixed and I'm wondering if perhaps it has coincidentally fixed your issue.

Assuming fixed. This will be released in the next few days.
