The Dell XPS 9530, like previous XPS laptops like the 9520 and 9510 have dual speakers in
each channel.
If the ALC289_FIXUP_DUAL_SPK flag is not set in sound/pci/hda/patch_realtek.c only the
tweeter will work and therefore make the sound quality terrible.
This patch has not been tested but is derived from a previous patch attempt from a
different user called Pentracillin which was rejected.

I don't have much confidence that this patch request will meet the requirements.
