Intel High Definition Audio (Intel D945GNT MB) no audio in FC4

Jeffwsi · #1 7th July 2005, 09:50 AM

Greetings..

I have installed FC4/i686 on an Intel D945GNT motherboard. The install was fresh.

I have not been able to get a peep out of the audio device even though it was automatically recognized during intallation and some modprobe.conf entries were generated. I have read many posts here about the Intel High Def Audio and have tried several things but none work. I am hoping some kind soul reads this and takes pity on me as I have burnt hours on this with no results..

Anyone have ideas as to why this is not working?

Thanks!

Have you updated you system to the latest alsa and kernel 2.6.12. Alsa 1.0.9 is required for Intel hi-def audio to work. The 2.6.12 kernel version has alsa 1.0.9 built in to it so you might have better luck if you update those 2 things.

Jeffwsi · #3 11th July 2005, 04:43 AM

I have both 2.6.12 and alsa 1.0.9 and it is a still a no go. I have been digging and I think I know the problem...

The D945GNT motherboard has Intel HDA based on the Sigmatel 9923 codec. After digging into the kernel source for 2.6.12-1.1390_FC4 I found that there is no support for the stac9223 codec. The snd_hda_intel loads but the codec seems unsupported.

If I run alsamixer or the Gnome mixer I only get a PCM device to set/enable/disable and I should have many more devices and switches.

Anyone know of a way to get Sigamtel stac9223 codec support??

Thanks!

I had no sound at first, and I added an external amplifier in volume control.. Works great now.

Jeffwsi · #5 11th July 2005, 05:52 AM

How did you do that? Can you explain in detail?

steve941 · #6 11th July 2005, 06:09 AM

Run gnome-volume-control by clicking applications then sound and video then volume control. Now click edit, preferences, scroll to the through (should be at the bottom) and look for External Amplifier, click it, click close. A new tab will appear in volume control called Swithes, your sound should now work if not make sure all the options in Playback are high and unmuted.

Jeffwsi · #7 19th July 2005, 03:28 AM

When I do that the only option I get is "PCM". Nothing else.

I have since discovered that Intel's HDA utilizes a number of different audio codecs. It turns out the Intel HDA on the D845GNT motherboard uses an 8-channel 7.1 codec made by Sigmatel, model 9223 (STAC9223). There is no support for this codec in the Intel HDA (snd-intel-hda) kernel module. The STAC9223 is latest/greatest stuff so it will take someone with connections at Sigmatel to get enough data on this chip to generate a working driver.

Life without sound is so....... quiet. =(

Jeffwsi · #8 20th July 2005, 06:01 AM

I found the answer to get the Intel HDA based on Sigmatel's STAC9223 7.1 8-channel codec under FC4.

Download, compile and boot 2.6.13-rc3 from kernel.org. In this version patches for the STAC9223 has been added to the sound/pci/hda driver source.

Once I rebooted this new kernel and ran alsa-mixer or gnome-mixer I had the correct devices. Add the xmms w/ mp3 rpms from FC3 and I'm golden.

daneel971 · #9 20th July 2005, 06:54 AM

did you managed to control volume and to get 5.1/7.1 sound?

Melio · #10 3rd September 2005, 09:05 AM

Steve, I had someone with a dell inspiron try your method and it worked for them.

nice work finding this out.

rathed9 · #11 4th September 2005, 11:49 AM

If anyone can now figure out why a Fujitsu laptop with the usual integrated AC97 sound card has no sound (running KDE) even tho the volumes are up on alsamixer and kmix....we can make enough noise to wake the baby....heh

Jeff, thanks for the info.
I hate to say it but I'm new at this and hoping to do what you've just suggested. Could you give me more explicit instructions? I'm trying to upgrade from 2.6.12-1.1447_FC4-x86_64.
Thanks

roberto8080 · #13 20th October 2005, 06:54 AM

I'm running FC4, updated the kernel to 2.6.13 (smp) and the sound from D945GNT works well but I hear a background noise when sound is playing, anyone else is experimenting that?

It's a little annoying

People

Thanks for the information, I am new at Linux Fedora Core 4, could you please post the details of the solution of these problem, principal ,the part of the dowinload and the compile part.

I hope you please help us.

Regards

alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel

For me it sound like your system is recognizing your sound card but is immediately removing it...
You should remove (comment):

alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
and, the most important :
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel
that line is removing your devive from the confguration... Even if you have an alias for it, if the reference does not exists, you sound processes will be dumped to /dev/null ..

This is it! It worked for me with my SBLive, I had the same problem.
