[Launchpad Bug Tracker <2111569@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

My Nvidia card is model GT710. 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.

Many thanks
