Properties

Description

HalAudioSink allows access to output of sound devices by specifying the corresponding persistent Unique Device Id (UDI) from the Hardware Abstraction Layer (HAL) in the "udi" property. It currently always embeds alsasink or osssink as HAL doesn't support other sound systems yet. You can also specify the UDI of a device that has ALSA or OSS subdevices. If both are present ALSA is preferred.

Examples

hal-find-by-property --key alsa.type --string playback

list the UDIs of all your ALSA output devices

gst-launch -v audiotestsrc ! halaudiosink udi=/org/freedesktop/Hal/devices/pci_8086_27d8_alsa_playback_0

test your soundcard by playing a test signal on the specified sound device.
