[imx8mm] tinycompress test tool not working on Yocto image

Hello,

I have imx8mm EVK platform with image:

LF_v6.6.52-2.2.1_images_IMX8MMEVK/imx-image-full-imx8mmevk.wic

flashed on it. When I was trying to use a test tool cplay that is shipped with package tinycompress, I encountered following error:

root@imx8mmevk:~# cplay test.mp3
Unable to open Compress device 0:0
ERR: cannot open device '/dev/snd/comprC0D0': No such file or directory

In fact, I don't see any comprCxDy devices under /dev/snd/, so modifying the tool call with flags has no effect as it always ends up looking for compress devices. Could you help me determine if it's possible to make this example work? I suppose tinycompress is installed mostly as a gstreamer dependency, but I was wondering if it can work standalone, e.g. via mentioned cplay tool example.

Hello,

Cplay is not the default in yocto bsp, you should try aplay -D plughw:0,0 your_sound.wav
