Description Fred New 2004-02-16 21:01:30 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6)

Description of problem:
I was able to configure this isapnp device using sndconfig in FC1.  My
FC2-test1 dmesg shows

pci_hotplug: PCI Hot Plug PCI Core version: 0.5
isapnp: Scanning for PnP cards...
isapnp: Card 'CS4235 CODEC'
isapnp: 1 Plug & Play card detected total
pty: 2048 Unix98 ptys configured

But when I run system-config-soundcard from Gnome terminal, I get the

# system-config-soundcard
** (system-config-soundcard.py:1941): WARNING **: `GtkTextSearchFlags'
is not an enum type

and a message window displays, "No soundcards were detected."

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Run system-config-soundcard from Gnome terminal or from Red Hat ->
System Settings -> Soundcard Detection

Actual Results:  No soundcards were detected.

Expected Results:  Soundcard detected and sound using the snd-cs4236

Additional info:

kudzu doesn't detect this device either.

Comment 1 Bill Nottingham 2004-02-17 05:23:51 UTC
There appears to be no isapnpmap files created by the kernel anymore -

Comment 2 Dave Jones 2004-02-17 12:32:02 UTC
I'm unaware we ever did generate any.

Comment 3 Bill Nottingham 2004-02-17 15:55:11 UTC
In 2.4, both ALSA and OSS generated ISAPnP module tables. Maybe it's a
module-init-tools misfeature. :/

Comment 4 Bill Nottingham 2004-05-25 16:32:26 UTC
kudzu isn't handling 2.6 ISAPnP correctly.

Comment 9 Kyrre Ness Sjøbæk 2004-05-26 17:18:06 UTC
Okay... I've confirmed that sound works when i do "modprobe
snd-sbawe", but how do I make this happen each time i boot the computer?

Comment 10 Andre Robatino 2004-05-28 10:23:01 UTC
  The CS4235 used to be detected and configured automatically at least
as far back as RH 6.0, but stopped being detected somewhere around RH
9, when sndconfig stopped being the default tool (sndconfig continued
to work until now, but it can't be used anymore).  The following 4
lines in modprobe.conf, inspired by using automatically generated
lines on another machine as a template and changing the driver, seem
to work for me (the install and remove lines are each one line that
appears as two due to wraparound):

alias snd-card-0 snd-cs4236
options snd-cs4236 isapnp=1
install snd-cs4236 /sbin/modprobe --ignore-install snd-cs4236 &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-cs4236 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-cs4236

Comment 12 Andre Robatino 2004-06-01 05:58:09 UTC
  Correction to my previous comment - the CS4235 stopped being
detected in RH 8.0, when redhat-config-soundcard (now
system-config-soundcard) became the default configuration tool.  This
tool has _never_ been able to detect the CS4235, though sndconfig
always could.

Comment 15 Michael R. Mayne 2004-06-22 15:47:59 UTC
We may be seeing some progress here - I tried the latest 2.6.7 kernel 
and the latest kudzu (kernel-2.6.7-1.441.i686.rpm, kernel-utils-2.4-
11.i386.rpm, kudzu-1.1.70-1.i386.rpm, kudzu-devel-1.1.70-1.i386.rpm) 
last night - kudzu recognised new hardware (YMH08xx) on reboot .  I 
haven't actually gotten any sound yet, but the volume control seems 
to work (doesn't immediately drop back to zero), and alsamixer 
immediately recognizes an OPL3SA2 sound card.  I think this is due to 
changes in the following file: linux-2.6.7\sound\isa\opl3sa2.c.  I 
did this on a fresh reinstall of FC2 with just the updates-released-
fc2 updates applied.  Any other updates from the development tree 
that I should apply?  BTW, where do I find the RPM GPG key for the 
Development (Rawhide) tree?


Comment 16 Bill Nottingham 2004-06-28 20:45:43 UTC
rawhide isn't signed, generally.

There is test code for this in development; the problem is that I
wanted to flesh out a few other (non-ISAPnP) bugs before doing a test

(And yes, the device descriptions for ISAPnP devices will be *ugly* -
there's really no correlating descriptive info from the kernel in sysfs.)

Comment 18 Chaz 2004-08-02 03:19:44 UTC
So, is there a fix out yet?

Comment 19 Bill Nottingham 2004-08-02 19:31:43 UTC
The package in rawhide may work for you.

Comment 21 Bill Nottingham 2004-09-30 04:56:20 UTC
1.1.91-1 will have better ISAPnP description strings as well.

Comment 22 Bill Nottingham 2004-09-30 05:06:50 UTC
Closing as 'rawhide'.

Comment 24 Andre Robatino 2004-11-10 09:08:47 UTC
  On a clean install of FC3, I get no sound even though modprobe.conf
appears more or less correct.  There is only a one-line difference
between the automatically generated file and the one I used in FC2 and
given in comment #10: instead of the line

options snd-cs4236 isapnp=1

the automatically generated file has the line

options snd-card-0 index=0

and I tried replacing this line with the original one with no luck.  I
tried fiddling with all the volume controls.  If this is confirmed,
this should be bumped up to FC3.

Comment 25 Bill Nottingham 2004-11-10 17:53:48 UTC
The failure of the sound driver to produce output is generally
unrelated to kudzu.

Comment 26 FC Better Than Windows 2004-12-01 07:05:22 UTC
I have tried to find correction for this bug for FC2, but it seems
that FC policy is not to fix anything for anywhere else than the
latest release. Is this correct intepretation?

Comment 27 Dave Jones 2004-12-01 07:07:20 UTC
the fc2 & fc3 kernels are 99.9% the same, so if this still affects fc2
with the 2.6.9 kernel update, it very likely also affects fc3.

Comment 28 Dave Jones 2004-12-01 07:09:16 UTC
brainfart -- ignore last comment, I just realised this is a kudzu bug,
not a kernel bug.

Comment 29 Bill Nottingham 2004-12-01 16:22:49 UTC
If there is a need to push another kudzu fix for FC2, this will
probably be fixed at the same time.
