Sound issues on Linux

[vdrn]

I've had multiple issues with sounds:

1. load_sound function returns before the sound is actually loaded. When trying to play it right away, it will be queued until it is really loaded and played then.
2. loading sounds is very slow (30 files 10-20kB each take well over 10 seconds, with seemingly exponential growth). load_sound functions return almost right away, but all sounds you try to play during these 10 or more seconds are queued and then played at almost the same time.
3. Disabling macroquad audio module (via default-features = false in cargo.toml) does not actually disable underlaying quad-snd import of native sound library. Because of this, you cannot disable macroquad audio and use another crate (as suggested in subcrates enable default features for the main crate #389 this might be connected to profiler crate)
