Hello Artyom,

Thanks for working on this, I am still procrastinating to comment. Tho, maybe it will help me to help with this issue about the library.
What is the problem with the libraries? Why test.scm does not import (srfi 253)?

By the way, an alternative form of:

  ;; It's possible that there are *no* audio devices available, in
  ;; which case open-device throws an exception.  In that case, return
  ;; #f.
  (let ((device (false-if-exception (openal:open-device))))
    (and device
         (%make-sound-system device ...)))

ref: https://github.com/scheme-requests-for-implementation/srfi-253/blob/master/existing-practice.scm#L293

It is possible to use and=> from the builtin guile env, and srfi-26 cut:

  (and=> (false-if-exception (openal:open-device))) (cut (sound-system <> ...)))

ref: https://www.gnu.org/software/guile/manual/html_node/Higher_002dOrder-Functions.html#index-and_003d_003e

In that particular case, it is easier to do:

  (guard (ex (else #f))
    (sound-system (openal:open-device) ...))

The form and=> is terse, handy, less general form of and-let*:

  (and-let* ((device (false-if-exception ...)) (sound-system (make-sound-system device ...))) sound-system))

Hope it helps,
