Solved (was: snd-hda-intel works only with acpi=off)

[jabol]

At mine laptop (A100-436, gentoo 2007.0 linux2.6.21) most of mentioned hacks were already included! Nevertheless sound is still not working... Yesterday it was, I wonder why (I recompiled my kernel since than but did not touch sound options)?

[boroshan]

[jabol]

Well, it's not too obvious. Firstly, because I use the in-kernel drivers. Secondly, sound works, it's only very quite! I can hardly hear anything at maximum volume.
For now I've found another solution... I've got an external USB soundcard that I can use, but this doesn't satisfy me. In this recompilation I included Acpi/Fan support and added suspend support. Now I've removed Fan again since I don't even know what this, but I don't want to try to remove suspend also. And it's still not working properly (maximum volume makes the sound barely hear-able).

[jabol]

Yes. Just as on the wiki mentioned on page 2 of this thread. The only thing is that all the patches that I should have applied were already included. It's a bit weird. The only thing that I done was to spoof the OS to Win 2006... I would try setting acpi=off and try it out, but I'm compilling openoffice now...
Funny thing is that my hda-intel devices mixer *has no* volume control! I can only set mic gain, no PCM/Speaker/Master!

EDIT:

It's possible to get the gpu fans working in a BIOS > 2.4. Essentially, in 2.4 there are hacks for a pre-release version of Vista that force the fan to remain a constant speed. Once Vista was released these hacks were removed (presumably they moved them to the WMI junk for Windows) and so a simple BIOS fix/compile isn't enough to fix the fan problem. You can find some good information for fixing it in > 2.4 starting about half way through the second page of this post: http://www.nvnews.net/vbulletin/showthread.php?t=75995

If any low level developers are following this post, let me know. If VTMP could be exposed via /proc/acpi/embedded_controller it would be trivial to write a fan controller daemon (But, I don't know enough about low level level stuff to know how to expose it). Hell, it might even possible to send the BIOS mods to Toshiba and convince them to use them. Probably wouldn't be a far stretch to then get nvidia to pickup the speed control code ("cat speed > /proc/acpi/embedded_controller/tosh_fan).

[boroshan]

Thanks for the link.

Basically, the idea seems to be to set the VTMP value to something low-ish (0x3C in the discussion) which gives you an always-on-but-not-overly-loud GPU fan.

I've just tried it here and it doesn't seem to have made any difference. That said, I believe I'm still on bios 2.4 so there may be other vista hacks sabotaging the attempt.

(This'd probably be better posted to the discussion on the NVidia forums, but I always have trouble posting there for some reason).

Well, that was painful.

I upgraded to 3.30, applied the changes shaundennie pointed out, made allowances for a different model (PSPA3E) as best I could... and it didn't work. In fact,
even with the computer basically idling (nothing but X) then temp still steadily climbed.

So I went to the tosh web site to get a downgrade and couldn't find one. I was sure I'd seen an archived downloads links somewhere, but nowhere in sight now. Never mind, I thought, I can use the backup the WinPhlash util made. If I run the toshiba .exe again I expect it'll detect that the bios is up to date and give me the option of reverting using the backup. At the very least it should do nothing since I'm up to date.

Alas what it did was reflash my bios, clobbering the backup in the process.

Luckily I found the remains of my 2.40 upgrade luring in the recycle bin and could use that to flash the bios back. If anyone has a PSPA3E stuck on 3.30, feel free to send me a PM.

Now I'm back in 2.40 and my CPU temp goes down as well as up, so some level of cooling must be taking place. I'd just like it to be a little more pro-active.

I have Ubuntu 7.04 32 bits (kernel 2.6.20-16-generic) on my laptop Toshiba Satellite P100-448 (Satellite P100 PSPAD - 01300WFR) with 1 Go Ram + sound card Intel Corporation 82801G (ICH7 Family) Conexant CX 20549 (Venice) + Bios Phoenis 3.30.
My problem is obviously that I have sound only with acpi=off !

1. I have updated my alsa-driver and lib and utils to the version 1.0.14 and tried few DSDT [http://acpi.sourceforge.net/dsdt/] but still no sound.
2. Is downgrading my BIOS to 2.40 is the final solution ? : where can I upload it ? (I'm french and there is no BIOS 2.40 on the Toshiba french site) and how can I proceed to downgrade ? (I'm a newbee and a little bit scared about the downgrading process : I can loose my guaranty if it fails)
3. Since the 27 th of June, there is a new version of BIOS (3.80). Will it solve the problem of sound+acpi ?

Thanks for your help

Hey guys. I've been closely examining this thread for the last two days and I finally fixed all my sound problems! Thanks guys! I have a Toshiba P105-s9337 with BIOS 3.80 . As some of you know (or not) toshiba locked this laptop from downgrading to the 2.40 BIOS although the components are exactly the same compared to an XP laptop of a similar model. Anyways I am using Ubuntu 7.04 (kernel 2.6.20-16-generic) and at first all I was missing was sound. Everything else worked fine (Wifi, GPU and CPU fans, etc) except for the Sound. I fixed the DSDT and recompiled it into the Kernal and all works fine! Wierd thing is that whenever I would boot with acpi=off Ubuntu would boot up and then I would get a blue screen telling me something about my video card and if I want to analyze the eror. When I hit no it would take me back to the black screen with text and just froze. Anyways, everything is finally fixed. Thanks to all of you for all the input.

hi guys,

i fixed few months ago the dsdt folloxwing your advices and i got the sound well on my festy. unfotunatky i tried to add 1go Ram and now
my linux is not starting anymore. i now this is linked to the dsdt nut i dont knopw what to change in it to fix it.

if i try to put the initialo dsdt the computer starts with the 2go ram but i ve no sound...


any idea?

thanks

Hello,
I've got a P100-197 PSPA3E (french model with 1Gb RAM) with a recent upgrade to BIOS v3.80
With this trick acpi, sound and gpu fan (constant speed) works for me.
I did following changes in my DSDT :
changed all the _T_0 to T_0, _T_1 to T_1, ... , _T_7 to T_7
changed the *PNP to PNP
added at the end of the BTST and EVNT methods

[rienko]

Lorang, can you post your modified dsdt, I have a similar model P100-195 PSPA6E and the fixes are not working with the BIOS v3.80.
They used to work with the 2.4.

Something that puzzles me,
the current decompiled ACPI (3.80) is missing all the code you posted from the _INI method which I distinctly remember fixing when I've done with a previous 2.4 BIOS.

Hopefully your DSDT can help me figure out what I'm missing.

[Martin LORANG]

Here you'll find my modified DSDT
Hope this can help you

Martin

[rienko]

Thank you Martin,
My acpi did feel strange compared to yours, so I booted a clean minimal gentoo live cd, extracted it from a non-poluted source and applied the common fixes.
Afterwards a diff between yours and mine shows me that our ACPI is exactly the same only the assembly time changes.

I've got the fans up and running, but I still have no sound, well at least I can work without burning my fingers .
I think the audio issues might be a kernel issue, so I will have the check that, since it stop working somewhere in the transition from 2.6.21 to 2.6.22.

Hello Everybody

I have a laptop Toshiba p100 (PSPA3E). But i haven't any song.
I'm a beginner on Linux and i don't understand all of your conversation.

Is it possible that one of you help me?
I would like you give me all steps to writ in the "Terminal".

Ifesle, maybe is there any frensh guy to help me?

thx for you help.

I mentioned it elsewhere, but kernel 2.6.24 has support for connexant hda-intel chips built in.

Working fine here.
