From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

As far as I understand, audio cards hold a buffer of the audio that should be played at any time. If the CPU can't keep up producing new audio, it will loop to the beginning of the buffer. My guess is that when you suspend, the CPU stops producing new data before the audio card stops consuming it. And that's why you hear the last part for a short instant.
It also happens on my devices, and it's always happened on all my previous devices as far as I can remember.
Disclaimer: this is based on my understanding + a lot of suppositions. It might not be accurate.
