Description Piet E Barber 2001-09-04 15:33:53 UTC
Description of Problem:
Sound does not work on Toshiba Tecra 8100.  It worked in RH 7.1
sndconfig, when prompted to probe for sound on a Tecra 8100 will properly
detect the Yamaha 

The problem is sporadic and hard to track down. 

Version-Release number of selected component (if applicable):
sndconfig-0.65.1-1

How Reproducible:
On two different Toshiba Tecra 8100s, I have had spurious support for the
sound cards. 

I was writing the bug report for this, and miraculously, the sound started
working on my Tecra 8100 (without me doing anything)
(very frustrating)

Thankfully, my co-worker's laptop, another Tecra 8100, has no working sound
on his. 

I compared /etc/modules.conf. 

Here's mine:


alias eth0 3c59x
alias parport_lowlevel parport_pc
alias sound-slot-0 ymfpci
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null
2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null
2>&1 || :
alias usb-controller usb-uhci
options sb support=1


Here's his (and what mine was when sound wasn't working)
alias eth0 3c59x
alias parport_lowlevel parport_pc
alias sound-slot-0 ymfpci
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null
2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null
2>&1 || :
alias usb-controller usb-uhci


Whenever I had the /etc/modules.conf without the 'options sb support=1'
tag, I would get lots of modprobe errors [URL 1]

Steps to Reproduce:
1. Install system on Tecra 8100
2. run sndconfig
3. modprobe section fails (Screenshot in URL 2)
3a. (/proc/pci on system which failed is located at URL 3)


1. Write bug report to bugzilla
2. run sndconfig so that you can prove sndconfig is broken
3. modprobe section miraculously works. 
3a (/proc/pci on system which worked is located at URL 4)

Actual Results:
When broken: sndconfig successfully detected soundcard, but
when it attempted to load module, modprobe broke.

When I booted this morning, it miraculously worked, and I didn't even do
anything to fix it.

Expected Results:
I expected ymfpci module to correctly load, and I can't identify why it
sometimes works and sometimes doesn't.

I'll be happy to submit more information if requested.

You shouldn't need to use the SB support any more, I think.

Assigning to the kernel.
