Arh - fixed this one - I think on my Compaq V5214ea laptop.

I got this one off a Mephis support website, applied it to my Fedora Core 6
machine and sound SPRUNG into life.

From root:

1) update-pciids - this will update any updates to your laptop that are not
recognised from standard kernel idents.

2) aumix -q - this makes sure none of your settings for sound devices are set to
zero level.

3) Add the following file /etc/modprobe.d/snd-hda-intel 
add this line:
options snd-hda-intel position_fix=1 disable_msi=1

Save the file and wait 10 secs - if you have system-config-sound running on loop
in the background, you will suddenly find sound bursting out the speakers.

Aparently - this problem is caused by a IRQ problem - quote from Mephis page:;topicseen

The invalid_dep_range error is possibly related to position buffers and msi can
interfere with the irq settings.
As carlops mentioned, testing the new development kernel and alsa 1.0.13 might help.
This link mentions adding support for toshiba laptops to ALSA  kernel (the hg
version - patch hg-8781) 1.0.13
hg is alsa development though and it may not have been merged into 1.0.13 in time.

(This is a mass-update to all current FC6 kernel bugs in NEW state)


I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.

I am CC'ing myself to this bug, however this version of Fedora is no longer

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!

Comment 5 Jon Stanley 2008-02-08 04:24:35 UTC

since no information has been lodged for over 30 days.

Please re-open this bug or file a new one if you can provide the requested data,
and thanks for filing the original report!
