Sound/ACPI issues...

Fenster

These are in no way related, but I felt it better to keep it all in one thread.

Anyways, to business...

Sound:

First a little history on my problem... I made a DVD installation of Fedora Core 2 on my laptop-its a Toshiba Satellite A60-672, and the sound worked perfectly (2.6.5-1.358 kernel). However, there's no sound at all in the newer kernel (.521), even after I recompiled it and specifically included sound card support and specifically support for my card, the AI IXP 150 AC97 (I recompiled as the .358 kernel was having trouble with my video).

However, the sound module doesn't seem to be compiled in, which is the start of my troubles.

Firstly:

[root@fenster home]# /sbin/modinfo soundcore
modinfo: could not find module soundcore

[root@fenster home]# /sbin/modprobe sound
FATAL: Module sound not found.

The .config for the kernel shows it as a loadable module, even though I specifically wished it to be integrated.

Next up, my soundcard itself appears to be installed correctly:

[root@fenster home]# /sbin/lspci
(lot of crap cut out here)
00:14.5 Multimedia audio controller: ATI Technologies Inc IXP150 AC'97 Audio Controller

So this seems to be where I stand. I've tried recompiling the kernel four times now, but at no point has it included sound. This is really starting to bug me as all the advice out there boils down to "if you get really stuck, recompile"

I've searched high and low on Google, but to no avail. What patches and programs are out there that might help me in this situation?

Next up, ACPI:

I've a lot less detail to provide here as I'm unsure of the ACPI (and APM) console commands. My problem is in short that the fan on my laptop is apt not to work. What will happen is that I boot up, go about my work, but the fan doesn't operate, causing my system to overheat and crash. Next time I boot though, the laptop recognises that its overheated and then turns on the fan until the next time I reboot.

As with above, I've tried compiling it into the kernel, especially with the Toshiba laptop extras, which provide additional control over my power settings. Zippo. None of them seem to work.

As my laptop is used more or less entirely on my desktop, I'm not too pushed over conserving battery power, so I want the fan running the entire time. Is there a simple, direct way to just force my fan to run at boot time-strangely, considering this is a laptop, there's no options in my BIOS for power/APM settings.

leave it like that

you should have a modules alias file somewhere like I have /etc/modules.d/alsa

make aliases like this

alias char-major-116 snd
alias char-major-14 soundcore
alias snd-card-0 snd-cmipci
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
options snd cards_limit=1

or do it manually

try modprobing now, lsmod should show up something like this

snd_cmipci             29316  2
snd_opl3_lib            9216  1 snd_cmipci
snd_hwdep               7456  1 snd_opl3_lib

you cant modprobe em because you have already built them in, use aplay whatever.wav to test if its ok.

for acpi trouble
use the pci=noacpi boot option and see if it helps

Well this thread is a few days out of date as the boards just timed out when I tried to load 'em.

The laptop eventually just died as I wasn't able to solve this problem, so I swapped it for the next laptop up, the A60-692. So far I've had no ACPI problems, although sound can be iffy with the newer kernels.
