This logic did not belong to the channel configuration parser (only used by dvbbasebin) but to dvbsrc, which is the element directly using this value and honoring the "adapter" property. Allows previously non-working cases like this to work: GST_DVB_ADAPTER=1 gst-launch-1.0 dvbsrc delsys=11 modulation=7 frequency=689000000 ! fakesink
