snd_hda_intel with buffer_size set to 32768 sounds horrible. Kernel driver bug?

Fresh Debian Bookworm (v12) installation with alsa but no sound
server. aplay with no .asoundrc sounds great (default buffer_size is
16384). If I force the buffer_size to 32768 ([1]), then aplay sounds
horrible ([2]). Is this a kernel driver bug? (If yes, I'll log it at
https://bugzilla.kernel.org) I discovered this bug because pipewire
sets the buffer_size to 32768 hence it triggers this bug - I've logged
a bug against pipewire at [3]. Output from alsa-info at [4]. TIA.

[1] To set aplay's buffer_size to 32768, I use the following ~/.asoundrc:
pcm.!default {
  type plug
  slave {
    pcm {
      type dmix
      ipc_key 1234
      slave {
        period_size 1024
        buffer_size 32768
        pcm "hw:0"
        format S32_LE
      }
    }
  }
}
