Помогите с регулярным выражением :)

Нужно достать из кода ссылки вида
https://sXX.knigavuhe.org/1/audio/XXXXXX/X.mp3
, где X - числа.

Пробовал вот такое выражение:
[^0-9\,a-zA-Z](https:\\/\\/s[0-9]+\.knigavuhe\.org\\/[0-9]+\\/audio\\/[0-9]+\\/[0-9]+\.mp3)[^0-9\,a-zA-Z]

Код (входной текст), из которого нужно извлечь ссылки (они в выражении var player = new BookPlayer(...)):
