Intel HD audio confusion

Xamindar · Posted: Fri Feb 15, 2008 1:46 am Post subject: Intel HD audio confusion

The 2.6.24 kernel has lots of new options for the HD audio driver. How can I tell which ones I need?
I tried building them all, my sound did work.....sometimes. Then I would have to reboot to get it back.
Then I tried no other options and now I have no sound at all.

I can't say exactly what options you need to select, but it can't do any harm to select most of them, I would select all of the "HD-audio codec" options to be safe at least. Obviously you'll waste a tiny amount of memory and introduce some extra compile time, but that's all the harm it can do AFAIK.

Did you really have to reboot to get your sounds back? Did you try just restarting ALSA?

Cheers,

There is a bug report on this a similar issue with this driver. Please go to this URL to see the bug. I would suggest you make a bug report on the way that driver is working with your system.

Blessed be!

Xamindar, where do you get these options?
I'm trying to use 2.6.24-gentoo-r8 and currently have no sound (previous kernels worked perfectly).
When I configure my kernel using make menuconfig -> Device Drivers -> Sound -> ALSA -> PCI Devices and select Intel HD Audio, I don't get any other options whether modules or compiled in

This has only happened with 2.6.24 onwards. Previous kernels work perfectly. I've also tried the alsa-drivers package (slightly newer 1.0.15 while the kernel is 1.0.14) but that doesn't work with 2.6.24 either.

My chipset (Conexant) only got support in 1.0.14, so it should work with kernel 2.6.24, but dosen't.

Any ideas?

Thanks,
Roland.

I'm using all the options except Aggressive power-saving on HD-audio, because Alsa had a roft time at the boot about the mixer and also alsa didn't found my card.

I will inverstigate this more next time that I build the kernel for the 2.6.24-Gentoo-r3.

Oh dear. Now I do feel silly... :oops:

Hmm, seem to be using 2.6.23-gentoo-r8....

Please ignore me, I'll go away.

Ok, maybe 'now' I'll try 2.6.24

Yeah you are right, I did it in the past and I will do it again, I'm sure

Ok, now I am using 2.6.24 and strangely enough the kernel options are there and my audio works perfectly.

Who'd have thought.... :lol:

Hi!

I found it!

Compile driver with all codecs and look at /proc/asound/card0/. You'll find codecs you need.
