did you specify period time or buffer time for speaker-test since it use
max buffer size by default
if (! buffer_time && ! period_time) {
583 buffer_size = buffer_size_max;
584 if (! period_time)
585 buffer_size = (buffer_size / nperiods) * nperiods;
586 printf(_("Using max buffer size %lu\n"), buffer_size);
587 err = snd_pcm_hw_params_set_buffer_size_near(handle, params,
&buffer_size);
588 if (err < 0) {
589 fprintf(stderr, _("Unable to set buffer size %lu for playback:
%s\n"),
590 buffer_size, snd_strerror(err));
591 return err;
592 }
but your log seem requesting low latency instead of Max buffer size
