Not sure if you still have this issue, But I cannot reproduce this issue on my
NUC(PCODE:NUC6I7KYK-IDD).
# speaker-test -D hdmi:CARD=PCH,DEV=0 -t wav -c 6

speaker-test 1.0.27.2

Playback device is hdmi:CARD=PCH,DEV=0
Stream parameters are 48000Hz, S16_LE, 6 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 22 to 5461
Period size range from 11 to 2730
Using max buffer size 5460
Periods = 4
was set period_size = 1365
was set buffer_size = 5460
 0 - Front Left
 4 - Center
 1 - Front Right
 3 - Rear Right
 2 - Rear Left
 5 - LFE
Time per period = 8.530777

I tried with 2 last kernel branch mainline and drm-tip. both are work well.
mainline:git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
drm-tip:git://anongit.freedesktop.org/drm-tip
If you still have this issue, please have a try.
