alsasink: Changing the device property passed READY state is not supported
Submitted by Francesco Ceruti
Trying to change the "device" property of an alsasink element, after the pipeline is set to "READY", has no actual effect on the used ALSA device.
I've briefly looked at the gstaudiosink.c source, and as far as I can tell,
in the "gst_alsasink_set_property" function, the property value (GstAlsaSink->device) is changed,
but the real ALSA device reference (GstAlsaSink->handle) is not.
