You need PulseAudio 6.0 but otherwise yes, it works for me.
Since there's no way to get this working without using new userspace,
we're basically stuck with having to support _REV 5. And since we're
supposed to support old userspace basically forever, this isn't going
to be something that we can just remove in a few months. But since the
hardware is intended to be used in I2S mode, we don't want this quirk
to be there forever. So we're basically left with adding
CONFIG_ACPI_WORKAROUND_BROKEN_DELLS which enables the quirk, default
it to Y and then let distributions set it to N when they've got
sufficiently new userspace. Unless someone has a better plan?
Just to be clear, from the Dell side only the XPS 13 9343 has this _REV
behavior.
What's wrong with a DMI quirk until I2S is mature on the kernel side and
userspace is new enough in distros? Is it too early in boot for DMI
quirks? That would enforce that no other machines can use _REV value of
5 to detect Linux without breaking the 9343.
