Title:
  No sound via HDMI on older Nvidia card (using nouveau driver)

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  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
