no audio w/ ATI IXP SB400 SMBus


problem is, everything as far as 3 of us can see, audio sets up as it should, modules are loaded, settings configured, nothing is muted at all. I've tried ALSA and OSS w/ the same result. All seemingly loaded properly, but still no sound at all.

This is an Enpower 770 laptop from www.pcclub.com.

I've tried Fedora Core 5 mainly, but SUSE 10.0, 10.1, and Gentoo 2006.0, Mandriva 2006, Ubuntu 6, and Slackware 10 all produce the same result. Seemingly all setup and working fine, just, it doesn't make any sound at all.
I've even had this machine dual-boot w/ WinXP, made sure all volume settings w/ the function keys, and windows volumes were all set up as high as possible before I left windows behind (which btw sound works in windows no prob.)

windows audio drivers are here: http://pcclub.com/support_downloads_...745C2A3F17489A

I haven't a clue what to do to get this working, maybe someone can help me out.

That's odd... Alsa should make it work fine, even the 56k modem.

So you said you run alsamixer and the volume isn't down to zero?

The card requires this ALSA module: snd_atiixp (ATI-IXP southbridge AC97 audio) and module snd-atiixp-modem for the modem (ATI-IXP southbridge AC97 modem), which you probably have installed (assuming for the distros you named).

Refer to Alsa website if you have to (re)compile and/or install those drivers, is the best source:

http://alsa-project.org/alsa-doc/doc...&module=atiixp

And for installing the modem using cvs:
http://website.lineone.net/~bryanrpo...ixp-modem.html

This Alsa website page says that the alsa driver works fine with the ATI IXP SB400:
http://www.alsa-project.org/alsa-doc...dor-ATI#matrix

Hi, I'm back, it's a little bug with the rev 01, not affecting the rev 02 sb400.
This other thread can help: http://www.linuxquestions.org/questi...d.php?t=399114
Read it carefully.
Pay attention to this:
Quote:
# echo "7a 2090" > /proc/asound/card0/codec97#0/ac97#0-0+regs
# less ac97#0-0+regs | grep 7a
0:7a = ffff
and to this script: http://starynkevitch.net/Basile/sound_basile
Cheers.

The second link is a script actually, and it will not work, since that error tells us you need ALSA debugging enabled in the kernel (option CONFIG_SND_DEBUG), most kernels don't have this so you'll have to recompile and install a new kernel for testing it. If you don't rush with this, it may be a second option upgrading to alsa 1.0.10 or newer. This alternative involves installing snd_atiixp module from a 1.0.10 or newer alsa, as I said:

1- get the alsa-utils source package (I don't know what's your actual distro).
2- make sure you have installed the linux-headers package (must be consistent with the kernel you are
using, of course).
3- Change to dir where new alsa sources are installed now, (I don't recall where they will be)
ie: cd /usr/src/linux/sound/alsa-driver-1.0.10 or 11 or ~/tmp/sound/alsa-driver-X.X.XX
4- Be frugal, configuring just to add snd_atiixp module. Point to the kernel you are building the module this way: "./configure --with-kernel=/usr/src/linux-headers-2.6.X-X-XXX-XX --with-cards=atiixp" [replace X's with kernel version]
5- make
6- # make install (#: as root)
7- After installing the module do not depmod, just reboot.

If it doesn't work, you (or we) can adjust point 4, or going for option 1. If you choose to go for option 1, make sure you do _not_ replace installed kernel & its grub or lilo entry (we don't need another problem).

i'm currently running 1.0.11, tried 1.0.12RC, and i originally had 1.0.10

right now i'm messing around w/ the different compile options for alsa drivers to see if maybe i just skipped something simple ;-p

And still doesn't work following that instructions? In that case, you'll need Alsa Debugging enabled in your running kernel as I said before. And when you have that new kernel compiled and running with that option on, run "#modprobe snd-atiixp" run the script http://starynkevitch.net/Basile/sound_basile or (in case it doesn't work) the instruction:
Quote:
echo "7a 2090" > /proc/asound/card0/codec97#0/ac97#0-0+regs
and check the values are correct after, this way:
Quote:
less ac97#0-0+regs | grep 7a
So it have to show: "0:7a = ffff". In case everything was right, run alsamixer. Let me know what happened.

for some reason this won't allow me to write to the file ac97#0-0+regs, even though I'm root (no additional users were even configured), but, i will try these things and post result ;-p

It should allow you when you run the command with a new kernel with "Alsa Debugging" enabled.
On a different issue:

That isn't convenient. You need some other user just in case you lose root access.

More info if you need, the kernel config for alsa and oss must look _like_ this, I don't recommend _at all_ replacing this areas in your kernel config, reconfigure instead to have this options like this:

same here

This is an interesting post as I'm having exactly the same problems with my IXP SB400 AC97. Everything "seems to work", nothing muted, sounds load, but nothing comes out of the computer.
I'll be following this thread closely.

if you have the same issue, please feel free to post any findings, what you've tried, etc., i'll be back on track soon hopefully

my 2 cents

Hello. So I had (yes, I'm using the past!!) the same problem and got it solved after many hours of desperation by...
Doing hardly nothing. I had tried thousands of time to fiddle with the external amplifier on/off togle, and on one last try it seems to have done the trick.
I turned it off, rebooted, and I know have sound.

Meanwhile, I did tons of fiddling with everything else, so I don't know why or how this is so...

Anyway, regardless of all fiddling ... the definite position of external amplifier is OFF + REBOOT.

David
