I got mine in the beginning of August. Updated immediately to 2.02 BIOS.

I had already prepared for not having sound as I had read the Arch Wiki page, and was really struck with a surprise as one day after playing with merely the ubuntu sound settings (fiddling with system sound volume) the speakers suddenly started working. I did not make any notes of the occasion as I assumed there might have been a recent kernel or some other package update, and did not expect any regressions to occur. But they did a couple of weeks later and that's when I found this ticket for ALC287.

What makes tracking this down a bit trickier than just booting with earlier kernel packages is that I have fiddled with both alsa and pulse on the system (e.g. tried different kernel module options for snd-hda-intel) so my working state was never a vanilla install with some updates. I will nevertheless try to get back to a working configuration with some kernel and report back.
