Package: libasound2-data Version: 1.1.7-2 Many people use Alsa only with Debian and with Hifi speakers connected to analog out of the motherboard. However the audio device 0 is hdmi audio and you need to change it in /usr/share/alsa/alsa.conf: defaults.ctl.card 2 defaults.pcm.card 2
Many other Debian packages asks confirmation from the user when updating configuration files. The libasound2-data package should do the same.
