Hello,
I'm struggling with a very strange issue in my Octavia. It's 2021 RS model, with Canton. Sometimes audio just stops playing and when I touch volume control (up/down) it starts playing again but the side speakers don't work anymore, just the front one. After MIB reboot everything goes back to normal. I had this issue on 18xx software and now it's still happening on 1941. Does anyone experience similar issues or know how to solve this?

I can't recall if I had that issue in the past but my MJ21 got 2 dedicated updates for the canton amplifier in the past due to whatever reasons. I think you should talk to your dealer about that issue and give him a little hint towards the canton amplifier software/firmware.

Thanks, I already talked to a dealer and booked a slot for the Canton module update. Currently, I run on the 4015 version and 4019 is available (checked via OBD11).

It never happened again after upgrading from 4015 to 4019, so I think it solved the issue.
