As nobody replied, I have converted this into a formal bug report:
https://bugzilla.kernel.org/show_bug.cgi?id=60769

Haswell people, _please_ comment on the bug.

Xingchao, could you take a look at this bug?

I'll be off for traveling in this week.

sure, i will take a look at it.
But i'm afraid i cannot continue tracking from next week, i'm under
leaving process at Intel.

At first glance, i saw a lot of errors:

[  772.822663] playback write error (DMA or IRQ trouble?)
[  782.912776] playback write error (DMA or IRQ trouble?)
[  793.002904] playback write error (DMA or IRQ trouble?)
[  803.093052] playback write error (DMA or IRQ trouble?)
[  813.183205] playback write error (DMA or IRQ trouble?)
[  823.273217] playback write error (DMA or IRQ trouble?)

I know this issue on some Haswell ULT boards(STP/WTM1) because they
are not stable, and it's better to use latest BIOS image(V131 or
later).
The log message like below are not critical, in fact they're just
"Warning", it will not harm audio playback:
 [    1.803595] hda_codec: invalid CONNECT_LIST verb 5[1]:0

And seems the proper HDMI device should be pin6, i hope Alexander E.
Patrakov could help check below command at first:
speak-test -t wav -c 2 -D hw:0,7

And pleaset let me know can you reproduce this issue 100% on the same
board? Did you test on some other boards with same Hardware?

thanks

Best wishes to you, and good luck with a new job :)

But then please tell us the contact information of the person at Intel
who should be contacted instead of you for any further questions
related to HDMI audio on Haswell.

Thanks, I will try to update the BIOS and retest.

Same result. I guess I should update the BIOS first.

The issue is 100% reproducible on my board, and I don't have any other
Haswell boards to test.

btw, did you do any suspend/resume operation before the audio playback test?
if not, it's a new case. i found the issue only on some particular
boards after suspend/resume.

The issue is 100% reproducible without suspend/resume. Just in case, I
tested after one suspend-resume cycle, it didn't fix the problem.

On IRC (#intel-gfx) ohsix said that the bug
(https://bugzilla.kernel.org/show_bug.cgi?id=60769) may be graphics
related after all, but was too scared with the interrupt handling code
there. The contents of /proc/interrupts are attached to the bug, but
he said there is nothing interesting there.

BTW I am surprised that the bug is still assigned to Jaroslav Kysela
and not to Intel specialists (who are not even in the CC list of the
bug).

broonie@kernel.org asked to CC: him to the thread. As far as I know,
Intel tried to reproduce this bug on their hardware and on some OEM
boards, but didn't try exactly the same motherboard, and reproduced
another bug (files play silently but IRQs seem to come correctly).

It is interesting to know that today I found two people on FreeNode
IRC with the same board, and only one of them (rvalles) can reproduce
the IRQ problem. The other one (broonie) uses an older kernel
(Debian's 3.10-3, current unstable) and sees the "files play silently"
problem instead of the IRQ one.
