No sound on Intel HDA...

[abobrien13]

Simple problem to explain. The sound doesn't output on my Intel HDA audio (a Realtek inside) though my volume settings are correct, the card selected is correct, and the system recognizes that sound is being played back. Everything functions and looks normal, but the sound simply doesn't come out of my headphones which I tested fine in other setups. This wasn't a problem in Fedora 8 or Ubuntu Fiesty or Hardy on the same hardware setup.

Any ideas? Hints? Spiritual encouragement?

Thanks in advance!

You didn't say what computer system you have.

Confirmed. I have an Intel 945gn essentials motherboard with the Intel HDA chip and the sound never worked properly in Fedora 8 either (low volume regardless of settings).

Now, I've got no sound in Fedora 9. I don't understand why after the numerous posts about Intel based sound not working in F8, the Fedora team still haven't sorted this problem. Most of the previous threads on this blame PulseAudio but I have the same problems without it. It seems like an ALSA situation because my Gentoo install, based on OSS works fine. Hardy Heron doesn't work, Feisty doesn't work. Anyone see a pattern here?

The first problem is that ALSA is trying to support a zillion variations on the Intel HDA "standard", each with their own quirks. And sharing the same code tree. So they fix/add one card, and break some others in the process.

The second problem is that the people with non-working cards do not attempt to fix the ALSA code themselves ;)

Or submit detailed error reports to the ALSA bugzilla, then respond to questions and requests for testing sample code.

I submitted bug reports to ALSA last year and didn't see a response for a few months, so I stopped watching, knowing that F9 would be released at some time probably with a fix. I also kept a diary of all the updates hoping that one day I could just switch on and it would work.

I'm also learning to program as fast as I can. I could program years ago from the ZX Spectrum era through to the Atari ST but lost track shortly afterwards. I can't remember much from those days and it's taking some doing, especially since there is now 'fashionable' programming rather than just functional.

I don't suppose you know of any good tutorials on the Linux sound system and ALSA do you? I'm prepared to do a lot of work on this and improve my Linux knowledge at the same time.

See article (http://gentoo-wiki.com/HOWTO_Compile_Kernel_with_ALSA) for starters.

Hello:
If you have not already done so, you might want to install the kernel-doc rpm, then have a look under
/usr/share/doc/kernel-doc-2.6.2X/Documentation/sound/alsa

to get some more information.

I am like moonshinerat. The exact motherboard is a Gigabyte GA-8I945GZME-RH (Intel 945GC chipset). However, my sound worked fine in Fedora 8, but as mentioned, it didn't seem very loud in my headphones. It wasn't enough of an annoyance to really bother me though. I'm surprised to see that this is such a big issue.

Hi, i had a similar problem a long time ago, below is how i fixed it, this may not be the best way but it worked for me,(maybe for you?) also there are newer drivers available now then when i did this.
su
yum -y install gcc kernel-devel-$(uname -r) make
wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.14rc4.tar.bz2
tar -xvf alsa-driver-1.0.14rc4.tar.bz2
cd alsa-driver-1.0.14rc4
./configure --with-cards=hda-intel
make
make install
make clean
