I see this in the dmesg :-
[ 7.955515] rt286 i2c-INT343A:00: Device with ID register ffffffff is
not rt286
and this comes from :-
regmap_read(rt286->regmap,
RT286_GET_PARAM(AC_NODE_ROOT, AC_PAR_VENDOR_ID), &ret);
if (ret != RT286_VENDOR_ID) {
dev_err(&i2c->dev,
"Device with ID register %x is not rt286\n", ret);
return -ENODEV;
}
This means we are not reading the RT286 codec ID correctly over I2C. I have no
access to this HW so can
someone check the BIOS settings for RT286 and make sure it's enabled in I2S
mode.

Title:
Audio broken on 2015 XPS 13 (9343) in I2S mode in Ubuntu 14.10/15.04
Status in Dell Sputnik:
Confirmed
Status in linux package in Ubuntu:
Confirmed
Bug description:
(This is a public bug report for LP1402828.)
This system has a dual-mode audio with an HDA and an I2S interface.
Which shows up depends on the reported _OSI from the last cold boot.
Since the kernels in Ubuntu 14.10/15.04 (15.04 uses 3.18 currently)
report an _OSI of "Windows 2013", I2S mode is used for audio.
A workaround is to pass acpi_os="!Windows 2013" as a kernel parameter,
but this is non-optimal since the mode of the touchpad is affected. It
also results in an alternate, less used and tested path in the
firmware to be used.
See the attached dmesg log for details on where the failure happens.
Notably,
$ dmesg -t | egrep "(audio|snd|INT3438)"
dmar: ACPI device "INT3438:00" under DMAR at fed91000 as 00:13.0
snd_hda_intel 0000:00:03.0: enabling device (0000 -> 0002)

There's also a failure to load the codec firmware after a
suspend/resume.
