Sound and ACPI issues on a Toshiba A60 Satellite laptop


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.

Hi Fenster,

about the sound issue, I had the same problem after installing FC3 test3 on my A60-723.
Google gave the answer, the sound chip is detected both as soundcard aswell a modem.
The corresponding modules are snd-atiixp and snd-atiixp-modem.
What you can do is to add snd-atiixp-modem to the hotplug blacklist file at /etc/hotplug/blacklist and add modprobe snd-atiixp to /etc/rc.d/rc.local .

Don know yet how to solve the acpi issues.

Best regards,

Dick.

I'll give that a shot.

echo "force_on:1" > /proc/acpi/toshiba/fan

That will turn on your fan. One caveat, there are seem to be some Toshiba's that do not have Toshiba written bios's and do not work with the toshiba_acpi module.

FC2 has acpi and the toshiba_acpi in the kernel. Try lsmod and look for the toshiba_acpi module. It's there for my Toshiba M10-S405 with a default FC2 install.

Here's a web site that is much better at explaining all of this than I am. http://memebeam.org/toys/ToshibaAcpiDriver


Cheers.

Thanks for the link

Alas that its too late though, as the laptop finally croaked last night. I wiped the hard drive and got it changed for a new one today.

If all is well, the directory toshiba should appear under /proc/acpi. Within that, proc files exist for examining and changing the state of various devices. Generally any user may view the state, but changing state requires root privilege.

As an example, let's look at the LCD device status (lines that start with $ are entered by the user, the other lines are output):

$ cat /proc/acpi/toshiba/lcd
brightness: 6
brightness_levels: 8

Now let's change the LCD brightness:

$ echo "brightness:4" > /proc/acpi/toshiba/lcd

If doing this manually doesn't seem like much fun, there are a few programs that will monitor hotkeys and perform the approprite action:

* [hotkey daemon example] - from driver author
* [fnfx]
* [tclkeymon]
* [Wez Furlong's patch to ACPID]

Well after all my misadventures, my laptop finally died due to constant overheating and crashing. Nothing I tried remedied the situation, so at this point I'm going to mark it down as faulty hardware. I upgraded to the next model (clicky) while getting the old one replaced and so far I'm quite happy. Its far faster and ACPI and sound work perfectly. I also ditched dual boot and went with a full fedora setup, which is a first for me. So far so good.

The Toshiba A60 does not work with the toshiba_acpi module, there is an asus_acpi module according to lsmod.
Since the fan is not turned on by the os, /proc/acpi/fan/FAN1/state lists "status: off", I solved the cooling problem by adding the next to /etc/rc.d/rc.local :

echo "force_on:1" > /proc/acpi/fan/FAN1/state

Now the fan is always turned on at very slow speed on a cool system, speeding up to half speed at a processor temperature of 50 degrees celcius and running full speed above 65 degrees celcius and slowing down again when the temperature lowers.

If someone knows a better solution, please let us know too,

regards,
Dick.
