Hi Takashi/Alexander E. Patrakov,
2013/8/20 Takashi Iwai tiwai@suse.de:
Xingchao, could you take a look at this bug?
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.
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.
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).
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.
thanks --xingchao
Thanks, I will try to update the BIOS and retest.
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
Same result. I guess I should update the BIOS first.
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?
The issue is 100% reproducible on my board, and I don't have any other Haswell boards to test.
