[pulseaudio-discuss] - wrap around when recording output.monitor

I am seeing warp around happening due to overflow when doing the following.
parec -r --device=alsa_output.pci_8086_269a_sound_card_0_alsa_playback_0.monitor
output.raw --format=s16le --rate=44100 --channels=1
paplay --format=s16le --rate=44100 --channels=2
if i use parec with the same configuration as the sink that I am
playing the wave file on, then there is no overflow/wraparound. It
seems to be a problem with the remapping of the channels from stereo
to mono. Is there an additional gain stage applied in this remapping
that might be causing this?
I am using pulseaudio 0.9.14
