ffmpeg – Trying to record the screen with pauses (Ctrl-Z and fg): getting audio/video desync: audio still recording after Ctrl-Z

this is my script:

ffmpeg -f x11grab -video_size 1920x1200 -i :0+0,2640 \
    -f pulse -i alsa_output.usb-GN_Netcom_A_S_Jabra_EVOLVE_LINK_00113735E82E0A-00.analog-stereo.monitor \
    -f pulse -i alsa_input.usb-Focusrite_Scarlett_Solo_USB_Y7D1J3F0A66336-00.HiFi__Mic1__source \
    -filter_complex "amerge" -ac 1 \
    -vf setpts=N/FR/TB \
    -c:v libsvtav1 -preset 6 \
    -c:a libopus \
    ~/record/out/$(date +%Y-%b-%d%a--%H-%M-%S | tr A-Z a-z).webm

Is something around -vf setpts=N/FR/TB?
