asoundrc

The .asoundrc file allows a user to leverage extra functionality offered by ALSA. This article is supplemental to the information available on the ALSA wiki

The .asoundrc file uses a simple syntax that is comprised of simple code blocks enclosed by curly braces to create so-called definitions. Definitions can be created for two types of devices:

1. pcm devices. These can be actual hardware or virtual devices created in the .asoundrc file itself.
2. ctl devices. These comprise how programs can modify specific parameters of hardware or virtual devices.
