Position mask should be build out of masks rather than channel values.
Try to create a wav file with following channel map:
Channels: 10 (front-left, front-right, front-center, lfe1, rear-left, rear-right, top-front-left, top-front-right, top-rear-left, top-rear-right)with
gst-launch-1.0 -v audiotestsrc num-buffers=10 ! "audio/x-raw,channels=10,channel-mask=(bitmask)0x3303f" ! wavenc ! filesink location=out.wav- Before patch:
