# NAME

`audiocfg` —
configure default audio device

# SYNOPSIS

`audiocfg` | `list` [index]

`audiocfg` | `default` index

`audiocfg` | `set` index direction encoding precision channels sample_rate

`audiocfg` | `test` index

# DESCRIPTION

The `audiocfg` utility helps maintaining the audio and mixer device symlinks.

Run with “`list`”, it lists the available audio devices and shows the currently selected default audio device.

Run with “`set`”, it sets the hardware format. The direction is represented by either of 'p' (playback) or 'r' (record), or both of them. This indicates the direction you want to set. The remaining parameters encoding, precision, channels, and sample_rate indicate the hardware format you want to set. These parameters must be selected from the candidates displayed by `audiocfg` `list`.

Called with “`test`”, it plays a tone of 2 seconds for each channel of the device with the index index. Called with “`default`”, it sets the default audio device to the one with the index index.

`audiocfg` needs access to /dev/drvctl and write access to /dev (when used with “`default`”) to work.
