Properties

Description

HalAudioSrc allows access to input 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 alsasrc or osssrc 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 capture
list the UDIs of all your ALSA input devices
gst-launch -v halaudiosrc udi=/org/freedesktop/Hal/devices/pci_8086_27d8_alsa_capture_0 ! autoaudiosink
You should now hear yourself with a small delay if you have a microphone connected to the specified sound device.
