Firmware update?

I’m a bit of a noob so bear with me…

I’ve got a problem with Kodi and some glitchy sound via hdmi to my tv. A thread on the RPi forum suggested updating firmware.

I’m running an RPi 3 Model B (armv7l) - v6.7 of DietPi . Im just wondering if there is a firmware update for it and if so how I would go about applying it?



With firmware is meant the kernel version. You can simply update it via

apt update
apt full-upgrade

If there is a hint that a Kodi/sound related fix available within the testing (master) branch of the kernel, then you could try to apply it via

dietpi-config > Advanced Settings > Update firmware


Also consider to update to the current version of DietPi, which include APT updates.
