Nvidia 8200 Slack 12.2 no audio

phantom_cyph · 06-30-2009, 02:14 AM

With 12.1 it works out-of-the-box. However, 12.2 is a different story. If I try and even start alsamixer I get the following:

Code:

alsamixer: function snd_ctl_open failed for default: No such file or directory

If anyone has any idea what the issue may be I would greatly appreciate it.

This might be a dumb question with an obvious answer: have you run alsaconf?

H_TeXMeX_H · 06-30-2009, 07:35 AM

Also make sure '/etc/rc.d/rc.alsa' is executable.

phantom_cyph · 06-30-2009, 12:59 PM

Did all that. Alsaconf returns no errors at all. Alsamixer returns the same error..

Can you post the output of 'lsmod', maybe some modules aren't loaded.

Here is the lsmod output:

All the snd_whatever modules appear to be loaded OK.

phantom_cyph · 06-30-2009, 01:36 PM

Apparently not if it doesn't work. Unless the modules are the problem.

Her's my lsmod results for comparison, if it's any use:

Almost looks like there's a missing /dev node relating to the sound system. Possible to compare /dev nodes on the working vs non-working system? If there *is* a missing node, it could be manually created, though that doesn't address *why* the node is missing (udev??).

H_TeXMeX_H · 06-30-2009, 01:51 PM

Check if '/dev/dsp' exists.

phantom_cyph · 06-30-2009, 01:54 PM

Wow! I got GrapefruiTgirl to come out for this one!

I've never actually had to mess with setting up nodes. Not sure how this is done, and what should I look for in /dev to see if I am actually missing it?

(Edit: /dev/dsp does not exist. what now?)

H_TeXMeX_H · 06-30-2009, 01:56 PM

Also, how did you install slackware, did you upgrade or do a clean install ?

LOL, am I *that* hard to find?

Well, I was hoping that you could compare /dev structure on the installation which worked, vs the installation that doesn't; but I suppose that if this is an upgrade, the working installation has been 'upgraded'!

There's a document floating around which lists ALL of the major/minor allocations for nodes in /dev which can be used as reference in case you need to create any manually.

Also, I would look in the udev rules on the system, and see what/if the necessary nodes are all being created.

For the record, exactly which type of audio device is on this motherboard? ie, a Realtek ALC888 or which?

If it were me (and it was not too long ago with my own sound chip) I would go about investigating the /dev nodes, and creating any that we guess maybe should be there that aren't (like /dsp as suggested above) and continue testing with alsamixer.

Good luck

Sasha

There is a /dev/dsp on mine.
