Bug#881715: alsa-utils: High CPU usage on the default device

[Andoru]

Forgot to check previously, but whenever I use those CLI players you
suggested, they also monopolise the soundcard, making me unable to play
other stuff in parallel, just like how it would happen when setting the
specific subdevice in VLC. So, since I'm not able to use those CLI players
to play with the default device to see if they use the same amount of CPU
as VLC and other players/apps, this issue is still not solved.
That's why I asked you for specific commands that I can use with those CLI
players.
