    @tlauda No, I played using I2S device ( -Dhw:0,0 ).

    This issues still can be reproduced on BYT platform. However, the phenomenon is very strange.
    I tested it on two similar devices (byt-nocodec) ,and one can reproduce it, another cannot reproduced it. It seems that this issue is not related to the sof version, and will suddenly appear from time to time.

    ack. will start checking tomorrow...

    @juimonen

    using latest kernel & fw, very easy to reproduce this error with pause/release:
    aplay: pcm_write:2011: write error: Input/output error

    attaching fw log, @tlauda any idea?
    byt_fw_log.txt

    is byt affected by the 3 periods change?

  10. juimonen commented on Oct 23, 2019

    @juimonen

    and the above was with nocodec topology

    @juimonen Could you verify if #1984 improves it?

  12. juimonen commented on Oct 23, 2019

    @juimonen

    @tlauda yes #1984 seems to help and I can't reporoduce it now.

  13. juimonen commented on Oct 23, 2019

    @juimonen

    @Jiangxinx can you also try/verify with #1984? my test's we're very minimal, but could not reproduce the issue..

    @juimonen @tlauda Very strange, I tried #1984 , I still can reproduce it on my device.

    @Jiangxinx Could you attach full log from sof-logger -t? Also does it reproduce only on one machine or on couple of them. This particular error looks like some kind of HW problem.

    @tlauda Yes, I tried two machines, another one still can not reproduce it, but my device is very easy to reproduce it.

    @Jiangxinx I have no idea what is going on with this particular platform. I can't reproduce the issue on any other BYT. After stopping and restarting DMA there is no interrupt coming and we cannot stop DMA. Hardware is stuck. Could you look for the differences between platforms? Maybe BIOS is different or has different settings? I've tried 3 different platforms and it didn't reproduce.

  19. juimonen commented on Oct 23, 2019

    @juimonen

    @tlauda @Jiangxinx same here also: I've been hitting the space bar like crazy in my byt-mb-> no error... it just works for me with #1984

    Close it as it is HW problem.
