No sound in OS when suspending `aplay` process

alsa-project/alsa-utils issue #243 was opened from syduki:

I'm using the [flac tool](https://xiph.org/flac/documentation_tools_flac.html) + `aplay` combo to play my lossless audio files, something like following:

`flac -cds filename.flac | aplay`

I usually suspend this process with `ctrl+z` when I need to temporarily switch to another sound-enabled application. That worked until recently when I upgraded my OS (Ubuntu 23.10, aplay-1.2.9, was 1.2.8). Now when suspending that process there is no sound at all in any of applications nor system.
