Dear Maintainer,

My Dell laptop using an "Intel Corporation Lunar Lake-M HD Audio
Controller (rev 10)" audio device has no sound.  pavucontrol shows only
the Dummy device.

My web search found this discussion:
   https://bbs.archlinux.org/viewtopic.php?id=310227&p=2
but apparently this regression was never fixed in the Debian kernel.

I'm currently using the kernel and firmware-intel-sound from Trixie backports.

My apologies if this issue should be addressed somewhere else.

Regards
Ralph
