I will just add that I have checked dmsg and found nothing helpful.
And just checked the kernel documention in
linux-stable/Documentation/DocBook/admin-guide/kernel-parameters.rst
which states:
-------------------------------
Module parameters can be specified in two ways: via the kernel command
line with a module name prefix, or via modprobe, e.g.::
(kernel command line) usbcore.blinkenlights=1
(modprobe command line) modprobe usbcore blinkenlights=1
[snip]
modprobe looks through the
kernel command line (/proc/cmdline) and collects module parameters
when it loads a module, so the kernel command line can be used for
loadable modules too.
------------------------------------
So modprobe is identified as the responsible component.
That documention may be out of date, of course.
I did try to look through git log for anything relevant, but didn't
find anything. Anyway, as I say, modprobe works just fine, but just not
during kernel boot for some odd reason.
Please help... I am wondering whether to bug report this against
modprobe. I did make a report against the kernel for want of anywhere
better, but kernel bug reports as so numerous, that I doubt that they
get read.
I didn't actually say which kernel. Here it is
6.10.6-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.10.6-1 (2024-08-19) x86_64
GNU/Linux
However, I think this problem only showed up after some other packages
upgrades. I did see
2024-08-26 15:31:22 upgrade kmod:amd64 32+20240611-1 33+20240816-2
2024-08-26 15:31:22 upgrade libkmod2:amd64 32+20240611-1 33+20240816-2
in /var/log/dpkg.1
But I think that sound was working thoughout August..
