audio: Fix various stylistic inconsistencies

- Indenting.
- Positioning of brackets and braces around if, switch and while.
- Position of * when declaring pointers.
- Always put braces around body of if statements, even if it's only
  a single line (it helps readability and avoids bugs when extending
  code if the scope is explicit).
- Remove spaces between brackets and arguments in function calls - some
  of the early code used this style but it's uncommon so remove it.
- Use Linux style multi-line comments.
- Use consistent initial capitalization of comments.
