Hello,

I am a mother board: ASRock M3AUCC
lspci shows:
01:00.1 Audio device: nVidia Corporation High Definition Audio Controller
(rev a1)


However, sound (system seting) shows only a dummy output for the
output.
No hardware!!
How can I see the real "card"?

Thank.

Are you really a motherboard? o-O

What is the program that shows you this?

Show what?
The system settings>sound
does not show any sound card (except the dummy one)!

Try
aplay -lv
If that comes up blank, it means that alsa doesn't recognize any cards
on your system. It is pretty good at recognizing cards (unless the
hardware is really new), so if is hasn't, I would suspect it is disabled
in the bios or there is a hardware error.

If your hardware is really new, you could load a related sound device
module and pass it options found in the kernel documentation for sound
to try to get some functionality out of it.

eg You have an ALC893 and the latest alsa supported version is ALC891.
You would tell the kernel to pretend your device in an ALC891 hoping
that the interface is nearly the same as your related ALC893.

If it doesn't come up blank, then you have a configuration error. I
advise installing pavucontrol and using it to configure your sound
device characteristics manually, since they weren't configured
automatically.

aplay: device_list:252: no soundcards found...

This is bizarre, to tell the true, this card had been recognized last
week, and I tried to test it. I did not get it working, by disconnecting
the cable, do you think that I may have kill it?

There are probably some tests that I can run.

Thank.

You don't say what kind of card or system. But if it sits in a slot, I
recommend that you remove it, dust / clean it, and reseat it in the
slot. While you have it out, take a look at it for damaged components.
I have never experienced a problem from plugging / unplugging a cable
from a hot card, though it is probably best not to do that. However, the
mechanical action of pushing the cable in could have displaced the card
in its slot.

> There are probably some tests that I can run.

Alsa is low level; it is assigned devices by the kernel which scans to
determine hardware. If the kernel doesn't find the device, it is
unlikely any other test will.

I test the card with a knoppic distribution and it works fine:
To my knowledge, it a AMD SB600 chipset and the audio is:
5.1 CH HD Audio (VIA® VT1705 Audio Codec)

but aplay: device_list:252: no soundcards found...

Probably the driver is mising in the kernel
and I need to add the module?

So, the hardware is OK. Next step would seem to be to test it with a
liveCD of F16. If that works, then it is something in your
configuration blocking it. Look in /etc/modprobe.d/blacklist.conf to see
if it is blacklisted for some reason. This is a long shot.

Seems like as good a reason as any. But why?

The kernel alsa sound docs suggest that this card is automatically
supported.

VIA VT17xx/VT18xx/VT20xx
========================
auto BIOS setup (default)

So it might be that the Knoppix kernel has the sound driver compiled in
rather than loading as a module, thus bypassing any module loading
issues.

You could try, as root,
modprobe -v VT17xx
to see if it will load the driver. If it doesn't, it should give you
some errors.
