Recent versions of ALSA now set up software mixing automatically (or so I'm told), which is what lets you play more sounds at a time than your hardware is capable of playing by combining them in software. This is a big deal for anyone who uses onboard sound, since it usually only allows ONE sound to be played at a time. asound.conf is the ALSA config file that lets you modify the properties of your hardware, and is generated by alsa-utils. Debian-based systems by default do not allow packages to overwrite or remove the user's custom configurations, so the old file was left in place. ALSA probably used the options in that old file rather than its automatic configuration, so it didn't set up software mixing. Attachment:
