SNES audio crackling on some games (video inside)

[Querpmuerp]

I'm using Retrix on my Xbox One S and noticed some audio crackling on different games like Yoshis Island or Super Bomberman 4. I made a video of it, please skip to 1:10: https://www.youtube.com/watch?v=biZGeqJXuWI&feature=youtu.be

I added what looks like the solution as the last post.
If there is anything I can do like testing, please let me know.

I tried it on PC and ran into the same issue (just play the first level of Yoshis Island).
On both my Xbox and my PC i run Retrix 2.1.1.0.
Other games I noticed this were Super Bomberman, Super Bonk or Demons Crest.

I tried setting my Xbox to 720p and it helped a lot, but still there is some crackling (enough to be annoying).

I think I found the solution in this thread: http://www.snes9x.com/phpbb3/viewtopic.php?f=6&t=5289
I installed SNES9x on my PC and had the same crackling noise in some games, so I changed the input rate from "automatic input rate" with the value 32104 down by 100 to 32004 as stated in the thread.
Even SNES9x says "if you experience crackling you can try lower this setting" when hovering over the slider :) Please adapt this change to Retrix, playing SNES on the Xbox would be so much better,
