This also happens on a GT 610 card. Both cards are no longer supported by official Nvidia drivers but for a media centre PC they are perfectly fine. Ubuntu 22.04 - video and sound work fine Ubuntu 24.04 - video works but sound does not I am not a very technical user but so far my tests with changing the kernel (in both 22.04 and 24.04) have concluded the following: kernel 6.6.63 and below - sound works well over HDMI kernel 6.7.0 and above - no sound over HDMI I've tried to report this as a kernel bug but I get redirected to Ubuntu, then in the Ubuntu bugs place I have been redirected here. I am managing to use 24.04 successfully at the moment by using an old kernel but this is not ideal. Please help.
