[gentoo-user] alsa-driver

[Ken Gypen]

Hi fellow Gentoo users,

Today I updated my working alsa-driver to version 1.0.14_rc4 and when I 
restart /etc/init.d/alsasound I get following error:

# modules-update -f && /etc/init.d/alsasound restart

 ERROR: Failed to load necessary drivers
 * Service alsasound started

But there (obviously) is no sound... So I tried rebooting to ensure 
proper reinsertion of the modules. This was no avail.

The dmesg output (referred to by the error) is:

snd_intel8x0: Unknown symbol snd_free_irq
snd_intel8x0: Unknown symbol snd_pci_quirk_lookup
snd_intel8x0: Unknown symbol snd_request_irq
snd_intel8x0: Unknown symbol snd_free_irq
snd_intel8x0: Unknown symbol snd_pci_quirk_lookup
snd_intel8x0: Unknown symbol snd_request_irq


Reverting back to the previous version fixes the sound once again.

Any advice?

Kind Regards

not sure, but maybe you ran into compiler incompatibilities. Anyway, I 
wonder why all people still try to install the alsa-driver package. You 
don't need it as all drivers already are in the kernel.

In the case of some drivers (such as intel hd audio) I have found the userspace drivers to be far superior to the kernel modules which gave poor sound quality, incredibly low volume even when turned fully up, and frequent distortion.

using the alsa-driver package makes sense to get more recent drivers 
(that's why it exists). But the mentioned snd_intel8x0 in the kernel 
should work very well.

I'll believe you, although your terms are wrong.  The alsa-drivers package 
include the out-of-tree kernel modules, not userspace drivers.  They still 
operate entirely in kernelspace, they are just not shipped with the kernel 
(like the kqemu module or the nvidia module).

I think the poster is talking about snd_hda_intel, not snd_intel8x0, which is 
a different module. The version of snd_hda_intel in kernel doesn't work well, 
but fortunately it is being actively worked on by one of the alsa devs, so 
that  version 1.0.14_rc1 of the alsa-driver package is much better than the 
kernel version.

No, I was actually referring to the snd_intel8x0 module. On my laptop 
(which gave the errors) the in kernel driver doesn't work correctly. 
Lots of distortion and low volume.

For now I've masked the newest version. Should I file a bugreport?
