I got the same issue here when using alsa with my own app :

snd_pcm_update_hw_ptr_pos: 9 callbacks suppressed

snd_pcm_update_hw_ptr_pos: 8 callbacks suppressed

snd_pcm_update_hw_ptr_pos: 9 callbacks suppressed

snd_pcm_update_hw_ptr_pos: 8 callbacks suppressed

snd_pcm_update_hw_ptr_pos: 9 callbacks suppressed

and so on..
