Red Hat Bugzilla – Bug 456698
Module snd-sb16.ko fails to build in a custom kernel.
Last modified: 2009-09-02 05:00:51 EDT
Description of problem:
Attempts to build the snd-sb.ko module to support the use of an ISA bus CT4180
sound card (uses Creative Vibra 16C chip) in a customised kernel (ISA bus & ISA
PnP support enabled) will fail due to the ‘struct snd_sb’ having no member named
‘rmidi_callback’ in the file sb16_main.c and sb16.c
Version-Release number of selected component (if applicable):
How reproducible: Always.
Steps to Reproduce:
1.Configure a kernel: Bus options --> ISA support [y]; Device drivers --> PnP
support --> ISA PnP support [y]; Device drivers --> Sound --> ALSA --> ISA
devices --> Sound Blaster 16 (PnP) <m> and Sound Blaster 16/AWE CSP support [y]
Actual results: Fails with following message -
sound/isa/sb/sb16_main.c: In function ‘snd_sb16dsp_interrupt’:
sound/isa/sb/sb16_main.c:407: error: ‘struct snd_sb’ has no member named
sound/isa/sb/sb16_main.c:408: error: ‘struct snd_sb’ has no member named
make: *** [sound/isa/sb/sb16_main.o] Error 1
make: *** [_module_sound/isa/sb] Error 2
Expected results: Kernel rpm files built.
Additional info: This issue was discovered by a member of the CentOS Community
and is detailed here
Although ISA bus and this sound module support is not part of the default kernel
configuration, source code present should compile without error.

Thank you, Prarit. I'll test this fix in a couple of days and report the result
Now I've tested the patch in Comment #2 and can confirm that CentOS kernel
2.6.18-92.1.6.el5.bz_pre53 compiled all right with the options mentioned by Alan
Bartlett in Step 1. of bug opening.
In addition, sound using SB16 ISA PnP (Vibra 16C) sound card now works in my
PIIX4 Celeron box flawlessly. Many thanks!

You can download this test kernel from http://people.redhat.com/dzickus/el5
Please do NOT transition this bugzilla state to VERIFIED until our QE team
has sent specific instructions indicating when to do so. However feel free
to provide a comment indicating that this fix has been verified.
Thank you, Don. I'll try the new kernel in a few days and report back here...

I am pleased to report that the 2.6.18-132.el5 kernel indeed has solved the ISA SB16 sound card problem in my case.
I built a custom kernel from source in http://people.redhat.com/dzickus/el5 and in xconfig added support to things mentioned in Step 1 of original bug description (except Sound Blaster 16/AWE CSP support).
The kernel compiled without error and the SB Vibra16C PnP ISA sound card now works well with eg. Rhythmbox. Many thanks to all who contributed!
Thank you for testing this with the original hardware Antti. Your assistance is appreciated.
So that's a "thumbs-up" ACK from here, Don.
