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".
