AUDIOCFG(1) FreeBSD General Commands Manual AUDIOCFG(1) 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. FILES /dev/audio Symlink to default audio device. /dev/audio[0-9]* Available audio devices. /dev/audioctl Symlink to default audio control device. /dev/audioctl[0-9]* Available audio control devices. /dev/drvctl Used for finding the corresponding audio driver to an audio device. /dev/mixer Symlink to default mixer device. /dev/mixer[0-9]* Available mixer devices. /dev/sound Symlink to default audio device (for the difference to /dev/audio, see audio(4)). /dev/sound[0-9]* Available audio devices.
