Could you check the raw hwptr and applptr values surrounding the error time, e.g. with the patch to alsa-lib below? If it's really hwsync that makes values unstable, we have to see the value skips there...
Does this help? Log attached. (head -n 100, tail -n 100)
Thanks. At least it shows the values in hwsync ioctl are sane. So something wrong in elsewhere.
Could you check whether this error happens with sync_ptr_ioctl flag in PCM config? For example, define the below in ~/.asoundrc,
pcm.mytest { type hw card 0 sync_ptr_ioctl true }
Then run with PCM "mytest".
