I would like Alsa to output everything at 44.1kHz (by default it looks like it's using 48kHz). I understand that the correct option would be something like: defaults.pcm.dmix.rate 44100But where should this be included: in .asoundrc or .asoundrc.asoundconf? Does .asoundrc override settings in .asoundrc.asoundconf? 
Setting Alsa to output 44.1kHz

Possible locations for the configuration file are /etc/asound.conf for all users, or ~/.asoundrc for a single user.The file ~/.asoundrc.asoundconf is a file created by the asoundconf tool, and should not be edited by hand.
