Thinkpad 770Z sound card not detected


hi all, I have IBM Thinkpad 770Z. Redhat 9.0 installed. Problem is there is no sound card detected. I have been tearing up Google and forums for weeks, with no avail. I was refered here by the guys over at NForcersHQ, they claim you guys are the best there is.

I admit I am new to linux and am definately far from knowing the ins and outs of the OS. I tried Mandrake, and Slackware first, but have finally settled on Redhat, the layout seems to suit me better for now.

heres the skinny

Redhat 9.0 does not detect a sound card at all, if I can get it to detect a sound card maybe I can figure out something from there, but maybe not...LOL

Mandrake 9.1 detected a Cirus Logic Soundfusion 4610 but would not work, I tried several different combinations...snd-cs46xx and standard cs46xx, I did not try the generic soundblaster driver as I did not come across that thread until after installing redhat

Slackware 9.0 also detected the same card as mandrake but did not work either


I tried to install the latest ALSA drivers on mandrake, but had problems with my source code install (my fault, I hope I got that fixed with the radhat install)


any help will be appreciated, Thanks All!!

update: I installed the alsa 0.9.6 driver anlong with the lib and utils packages.

sndconfig now detects Cirrus cs4610 Coldfusion sound card, howver is says that it is not supported.

it there a way to enable support?

I have found that it sopposed to be soundblaster compatible, but how do you get it to recognize as a sb?

ok I got the sound working

after i installed the alsa drivers, I then had the ability to run sndconfig

I used sndconfig --noprobe to disable autodetection because it will select the cs4610/1 driver that doesn't work

I selected CS4232 driver with the following settings
io=0x530
irq=5
dma=1
dma2=0
mpuio=0x300
mpuirq=5

the sound works, now on to the next problem

video display is set as a generic laptop display panel 1280x1024 resolution
thousands of colors
31.5-67khz horizontal refresh
50-75hz vertical refresh
2956x3251 dpi

Trident Cyber 9397 DVD (generic) 8mb

problem is that when any game is displayed in full screen or at least in a window that encompases the majority of the screen, this happens

aproximately 25% of the diplay area on the left side will remain clear and unafected. the remainder clones the next 1/2 inch across the remaining 75% of the screen and it will not reset untill you restart X, and you have to do a forced shutdown due to the fact that if you slect the log off/shutdown from the main menu, the menu is displayed in the middle messed up portion of the display


any ideas or suggestions would be appreciated

Hi,

I have the exact same problem that you do, except I'm using Mandrake 9.1 on 770z. I have been trying to reproduce your steps to the hilt. I do not have ALSA drivers installed yet, as I have to build from the source and have the kernel source in my HDD, which I do not (to save disk space), so I'll have to do it later when I have more time (tomorrow).

In the meantime, I downloaded and installed sndconfig & all of it's dependencies that I did not have, and tried to run it, but the bloody program hung and did not do anything. Will this happen until I install alsa, or is it something else. DId you encouner this when you were installing your cs**** drivers? Please do let me know. I'm going nuts here. I have to boot to WINDOWS (yechchchc) to listen to sound.

Regards,
AR

OK here's what I got. If you got sound config to load you don't need the alsa drivers. the CS**** drivers work good for like cds or dvd sound, but for system sounds or games its all messed up, you need to use the soundblaster drivers use:

sndconfig --noprobe

sb

io=0x220

irq=5

dma=1

this driver seems to work much better.

on the install, sndconfig does hang for a moment and doesn't seem to do anything, took nearly a minute before mine responds, but it did finally proceed.

now in my quest to get eveything working, I have come across a bunch of different ways of getting the sound to work, some work, some don't, the sb works best for me on my 770Z. Turns out this laptop actually has more than one sound chip in it...

I like the user name, I am a big Asimov fan too!

also I never had any luck at all with mandrake on this laptop (mandrake has a different directory stucture than standard linux) (you do not have to recompile your kernel to install the alsa drivers, you just have to find where in the heck mandrake installs the source files, i can't remember where I found them ---run updatedb then do a search for version h ,I think is how I found them),

however redhat was much easier, except no mp3 or dvd support which was fun.

get apt-get

if your not familiar with it, it is great, instead of having to download something, unpack then install

like the alsa drivers for instance, if you have apt-get all you have to do is type in

apt-get install alsa*

and boom it connects to freashmeat's servers downloads the drivers, libraries, utilitys and all and installs them all in one swoop.

note the * , you don't even have to know the whole filename!

Hi,

I did as you said, and I tried to load the cs423X driver first and then, failing that the sb with the io irq etc settings that you said. In both instances i got the following error message:

/lib/modules/2.4.21-0.13mdk/kernel/drivers/sound/sb.o.gz: x
x init_module: No such device x
x modprobe: insmod x
x /lib/modules/2.4.21-0.13mdk/kernel/drivers/sound/sb.o.gz failed x
x modprobe: insmod sound-slot-0 failed


What did I do wrong?

AR

I wish I knew,

come on somebody help us out here!

unless you have your heart set on Mandrake, you might try Redhat 9.0, it was the only one that I could get sound working properly using the sb method

I don't hav enough knowledge to help you any further at this point.

I tried both Mandrake 9.0 and 9.1 on my 770Z with no avail, on 9.0 I could'nt get teh sound to work at all, and on 9.1 the best i could get was a repeating echo every time a sound played.

their might be a possibility the MDK has dropped legacy support. and that is exactly what we have with the 770 series thinkpad, legacy.

Well,
Here is what I would like to do:

Keep the Linux Mandrake. Create a 2 GB Journalised ext3
partition and install Red Hat there (already have a swap) to see if sound works. I already have LILO running on the 1st sector of MBR. What I want to know is that when I install RH Linux, I presume the installer will autodect my windows and configure a lilo.conf file of it's own and rewrite the MBR or whatever. Question is, will it do the same for my existing Mandrake Installation? If not, how do I edit the /etc/lilo.conf file so as to tell it have an option in the menu to locate the vmlinuz file for the Linux Mandrake and boot it if neccessary? The reason I do not want to overwrite my MDK is because I have a lot of software and stuff there that I use like Open Office & tetex and libdvdcss and others and I do not want to overwrite them because if I do, and have to reinstall them, the redhat distro may not have the dependencies and I'll have to go through sheer hell trying to find them off the web because many of the rpm sites that uniquely contain rare dependies turn out to be duds .

Any suggestions on how to proceed with this safely?

I got sound to work on my thinkpad 770z just now.

But I did not have to use ALSA or anything. I pressed F1 during boot and disabled quick boot in the BIOS settings. Plus I used sndconfig to change my driver to CS4232.

look in
