[FFmpeg-user] Audio/video capture out of synchronisation. Is my fix right?

Hello
I use the following command:
./ffmpeg -debug 1 -f pulse -ar 44100 -ac 2 -channel_layout stereo
-thread_queue_size 512 -i alsa_input.pci-0000_00_14.2.analog-stereo -f
v4l2 -ts mono2abs -channel 1 -video_size 720x576 -pix_fmt yuyv422
-thread_queue_size 512 -i /dev/video0 -vf
drawbox=0:0:3:576:black at 1:t=max,drawbox=718:0:3:576:black at 1:t=max,drawbox=0:0:720:3:black at 1:t=max,drawbox=0:565:720:11:black at 1:t=max
-c:v ffv1 -level 3 -aspect 4:3 -pix_fmt yuv422p -c:a pcm_s16le
/Store3/Test/t_`date +%Y%m%d_%H%M`.mkv -aspect 4:3 -f sdl "Dazzle output"
See 1st output below
However even with -ts mon2abs option, I have a de-sync late audio of
around 150ms when I play the file with ffplay
I found a fix adding
-itsoffset -0.15
before
-i alsa_input.pci-0000_00_14.2.analog-stereo
See 2nd output below
This seems to work, remove the de-sinc but I have some very short
freezes in the sdl window. I checked the number of input and output
frames and packets, there are equal. Maybe this is only a display
freeze. Average CPU usage with System Monitor shows around 25-30%.
I want to know if this fix is OK.
BTW if I add -itsoffset -0.15 and I remove -ts mono2abs all is sync even
if start: of audio and start: of video are widely different:
