I tried manually changing the SDVOB bits, and it temporarily enabled
audio (until I changed from one video clip to another). There's also
other bits that differ so I guess that the channel mapping etc might be
messed up.
Attached is the output from intel_audio_dump with working audio (without
forced KMS mode) and without (with forced KMS mode). The diff between
them is:
