Cmi87xx works in 15.5; abandoned by 15.6?

In 15.5:

15.6 on same PC:

# lspci | grep dia
0a:02.0 Multimedia audio controller: C-Media Electronics Inc CMI8738/CMI8768 PCI Audio (rev 10)
# lsmod | grep snd
#

I tried yast2 sound module, but it can’t find any cmi87* driver that will load. Where does one look for missing 15.6 kernel module that 15.5 kernels provide? Is this a bug report time? A simple BZ search for cmi87xx returns Zarro Boogs found, as do cmi87, cmi8738, cmi8768, “cmi 8738”, cmi-8738 and other variations of the lspci report.

# modinfo snd_cmipci
modinfo: ERROR: Module snd_cmipci not found.

modinfo snd_cmipci to be at all useful would seem to require the containing package be installed first, magic that doesn’t come to mind when when one knows neither that those are the strings to search for, or that the project implemented some subtle policy change without including it in relnotes. :stuck_out_tongue: Not once did Google offer me those kinds of connections either. 'Tis bliss we have our malcolmlewises here. :grin:

In 15.2 and prior, nouveau and snd-cmipci were provided by the single kernel-default package. Now, each comes from a different package than the kernel it’s dedicated to. 29.05% additional installed “kernel” size over 4 releases/4 years because of the happenstance the PC is not using Intel graphics and Intel sound. :skunk:
