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

Okay, so I installed Arch from scratch with a minimalist set-up of OpenBox and tint2, installed alsa-utils and alsa-tools, and made that modprobe config file to disable HDMI output, just like I did when I did the netinstall of Debian. Then installed vlc and played all the files I played previously

Yes, I was about to do that. Though those distros all have PulseAudio by default, so I thought of installing Arch on a separate partition and test ALSA there.

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

Okay... then what is there to do next? Call me technologically illiterate, or say that I don't know of the inner workings of ALSA, but I don't think this can be a given that a simple task such as outputting audio could take 13-20% of a quad core CPU!
