[gentoo-user] ALSA config problem

[gentoo-user] ALSA config problem

[James]

 Quandry:

(2) ALSA drivers exist. No matter what kernel choices I make
I either get 2 different ALSA devices, or none.

The mobo has an Nvidia chip, the video card has a ATI video chip,
both only work under the Intel HDA driver. These are compiled
into the kernel, not loadable modules. I'm going bald googling
trying to find out what to do, or how to fix?


from dmesg:


Advanced Linux Sound Architecture Driver Version 1.0.17.
ACPI: PCI Interrupt Link [LAZA] enabled at IRQ 23

No sound. Kmix has a red X over it on my kde panel.
There are no choices there in Kmix to select on.
HOW do I set this up?   udev, hal, or evdev configs?


Ideas?

In the 2.6.28 kernel alsa is broken for hda-intel. Either use 2.6.27 series 
kernel or use a live alsa ebuild.

Makes sense, but, it's does not work for *26 or *27 kernels:


Linux sliver 2.6.27-gentoo-r8 #12 SMP Mon Feb 9 13:04:18 EST 2009 x86_64 AMD
Athlon(tm) 64 X2 Dual Core Processor 4600+ AuthenticAMD GNU/Linux


It's a new install, and it has never worked. It works find under XP.

Start with:

http://www.gentoo.org/doc/en/alsa-guide.xml
/usr/src/linux/Documentation/sound/alsa/ALSA-Configuration.txt

On my new install using 2.6.28-gentoo-r1, alsa kernel, sound as modules 
(recommended), snd_intel_hda, ~x86, I have both analog and SPDI/F 
working, but the kernel is not recognizing HDMI device.

In a nut shell,

* enable alsa in the kernel
* enable as modules device drivers/sound card support/...
* do not install alsa-drivers.
* emerge alsa-utils
* follow the alsa-guide
* if digital device not recognized, specify option name from 
ALSA-Configuration.txt

HTH,
Roy

Yep got these. They do seem to be dated, in light of the 
recent kernel changes related to audio....?

Well, for now, I went back to this kernel version:
2.6.24-gentoo-r8

Only one audio chip (nvidia) shows up, and I got it working now

I'll try a 2.8 kernel when the gentoo  sources go stable.

I appreciate these steps and refs....

I'm good for now.

As was suggested above you may get better luck building the alsa drivers as 
modules.  Although I had my sound card driver built in the kernel for the 
last 2-3 years, I had to revert to building it as a module to get it to work 
with kernel 2.6.27-gentoo-r6/8.

The main reason for building the sound drivers as modules is so that 
alsaconf can find and setup your sound card for you.

Why can I listen to music and watch DVD with my hda-intel, if it's 
broken?

Guess it's only broken for certain cards then?

I notice there are more options for the type of hda-intel card now, so
you may need to tweak that.  It took me a few goes to figure out I
needed the IDT/Sigmatel sub-type for the Dell/Intel chipset.

I wasn't recommending that we make the links for them, only provide them
with the tools to do so if they want to take the gamble (or the gambol).

Works for me.  In fact, I've never alsa, mixers, and sound working
better than in 2.6.28...

I have this card:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller (rev 02)
which has the pci id 8086:284b
