Subject: changing volume using alsamixer
To: gstreamer-devel <[hidden email]>

Hi,
i executed following commands
gst-launch audiotestsrc ! alsasink &
amixer set Master 10%+

it changed the volume for the test source playback.

Does amixer use alsamixer plugin internally?
is there any command for gst-launch to include alsamixer in the chain with some preset volume?
can this volume be changed dynamically?

thanks,
Sachin

I'd rather use the following pipeline, programatically: audiotestsrc ! volume ! alsasink

And play with volume's "volume" property, example in python:

vol = gst.element_factory_make("volume")
vol.set_property("volume", 0.8)

Cheers
