Both gst-launch-1.0 and aplay work if the default device is set to analog headphones in gnome-control-center, and do not work correctly if the default device is set to HDMI.
I tried the following: speaker-test -c2 -t wav -D hdmi:1,DEV=0 gst-launch-1.0 uridecodebin uri=file:///<path to music file> ! alsasink device=hdmi:1 and the sound is too fast in both cases.
