Updated Linux kernel on Debian stable (Trixie) on x86_64 from
6.12.113-1 to 6.12.115-2 and several hours later, noticed a segfault
with Firefox when I was not using it, only two tabs open with
gmail--segfault below.  Prior to this kernel v115, I have not had any
segfaults.  Are there any known issues with this updated kernel
version with respect to audio handling?

the system does have two audio devices but I was not using the
machine/audio at the time of the segfault
00:1f.3 Audio device: Intel Corporation Alder Lake-S HD Audio
Controller (rev 11)
01:00.1 Audio device: NVIDIA Corporation GB202 High Definition Audio
Controller (rev a1)

cacin in #debian on OFTC noted other users are also having problems
with audio with the new 115 kernel version:
