well,
i have been trying something similar before,
it goes something like the codes below,
*note that I'm using C

			audio_caps = gst_caps_new_simple("audio/x-raw-int",
			                                  "width",       G_TYPE_INT, 16,
			                                  "rate",        G_TYPE_INT, 48000,
			                                  "channels",    G_TYPE_INT, 2,
			                                  "endianness",  G_TYPE_INT, 1234,
			                                  "depth",       G_TYPE_INT, 24,
			                                  "signed",      G_TYPE_BOOLEAN, true,
			                                  NULL);
			g_assert(audio_caps);
			gst_pad_set_caps(audioconvert_src_pad, audio_caps);
			gst_caps_unref(audio_caps);



I run this before linking up the pipeline,
and so far i have tried numerous setting combinations,
so far i have no positive improvements yet.

so far only by replacing the audiosink to alsasink,
i can get good volume with the same setting on all the other part of the
pipeline.
i guess this part of setting could be the only connection to this problem.
