I assumed that it simply uses ALSA as a sink, so with the same audio device, it should be affected by the same limitations. Have you actually measured the latency difference between PulseAudio and ALSA? And are PulseAudio and ALSA really using the same audio device? One thing that comes to mind is the multi-channel feature of the LPass driver. It can use up to 8 channels, but period_bytes_min/max is fixed and not dependent on the number of channels. So if PulseAudio is configured for the full 8 channels, then maybe the buffer fills up 4 times as fast, leading to a quarter of the perceived latency compared to stereo mode. But that is just a wild guess. Looking at the PulseAudio config might clear things up.
