Topic: How to detect onboard (asus board) sound?
started by: mikshaw
Posted by mikshaw on May 25 2008,01:37I recently got a second-hand asus motherboard with an athlon XP 2000+ processor and 1gb ram attached. It has an onboard sound card that DSL doesn't recognize. I tried adding the soundblaster pci card I had previously used, which DSL detects, but the system freezes whenever audio is required, so I pulled the soundblaster out. I assume there is a conflict between the two cards. I can't find anything in the bios to disable the onboard audio as I did on my previous board.
Is there an app I can install in DSL that will let me discover what the onboard sound is so maybe I can load the appropriate driver? I didn't get any manual with the board of course, so I don't know anything about it other than the brand. I don't see anything in sysstats.lua that gives me a clue, but I'm guessing it may be via?
Thanks for any help.

Wouldn't that require a bit of a catch 22?
Anyway, I assume you already tried google and the motherboard model number right? Can you find a model number, so I can give it a shot.
Edit: If no model number, is the south or north bridge uncovered on the board? Can you remove the bridge heatsink to see, if it is covered? Or what does sysstats say for the bridge?
Posted by curaga on May 25 2008,08:03I'm surprised a motherboard this new still has an ISA sound chip..
Posted by mikshaw on May 25 2008,13:52Looking at the board now, it's Asus A7V333, which apparently uses (according to a quick google) VIA 8233A sound (AC97?)
EDIT: another search came up with this:
C-Media 8738 6-channel PCI audio controller
Maybe I should update the BIOS in hopes of having the ability to disable this controller?
In any case, DSL forums may already have an answer here, now that I have a better idea of what to search for (didn't find much just searching for asus and sound).

I have no idea if this is the audio, but it's the nearest I've come so far to finding anything with dmesg. Also no idea what that "interrupt pin A" message means.
On an unrelated note, the lucent winmodem I had been using on the other board wouldn't work on this board, so I swapped it for an older(?) model.
Posted by humpty on May 25 2008,17:09since you don't see ;
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97 Audio Controller (rev xx)
then it looks like it is not detected.
I used to have an Asus board. Does it look like to have a jumper that can enable/disable the onboard audio ?
edit: also found this;

(i guess you already tried < http://www.cmedia.com.tw/?q=en/driver) >
Posted by curaga on May 25 2008,17:15Try a bios update, and then these boot codes ->
found from google..
Also check if changing the "Plug and play OS" option in bios affects anything.
Posted by chaostic on May 25 2008,17:58It's a via combo bridge. I have a similar via based board
Your via chip and mine are driven by the same driver, so there's a chance you can use this info.
Can you check lsmod, see if any of those are loaded?
dmesg | grep -i "via"
since the driver doesn't have 8233 in it's name
And for the pin A thing, it seems that that might be an unsupported bios raid option thing with your motherboard.
Are you booting no-acpi? On mine, the acpi is 11.4, with the audio at 11.5. If you turn off the acpi, maybe that's disabling the audio along with it?
As for the possible c-media controller, you would need the c-media pci module, which dsl has as /lib/modules/2.4.26/kernel/drivers/sound/cmpci.o
And it might not be a c8738.
According to hardware4linux.info, it might be a ENS1371 Ensoniq / Sound Blaster 16PCI 4.1ch [Multimedia audio controller], but they have multiple a7v333 boards, listing either the cmedia or ensoniq controllers. None have a via bridge based controller. So try these first.

The ENS1371 is module
You might also want to try
modinfo cmpci es1371
to find some of their options.
Could there be any icq conflicts? Have you tried without the winmodem (I assume its pci, no?)
Finally, which slots are you using for the cards?
According to < http://www.techsupportforum.com/hardwar....ms.html >
There seems to be an issue with slot 5 and 3 on the a7v333. (remove any card in slot 5)
< http://forums.modojo.com/showthread.php?t=49054&page=5 >
there seems to be an issue with sound blaster live cards and the a7v333, in general. Do you have another one you can try?
Last, what revision number is the motherboard?
Posted by ^thehatsrule^ on May 25 2008,18:38... and you could just look on the asus site
Posted by mikshaw on May 26 2008,02:34The Asus site had nothing about this board, as far as I could find...it seems to be unsupported now, and the asus website lacks any logical navigation.
lsmod shows no audio
I tried both xubuntu and dynebolic, and neither distro detected the sound controller. I wonder if it might be broken, or maybe so old that it's obsolete.
I haven't tried the other suggestions yet. So far the bios updates I've found have been Windows binaries.
The suggestion about the slots is interesting, though....I've never heard about this issue. slot 5 has nothing, but slot 3 has a firewire controler.
board version number is 1.02
I tried loading sb and es1371 and both failed.
Posted by chaostic on May 26 2008,06:01Maybe that's why you got it second hand Happens to all of us.
From your lspci, the firewire controller isn't listed there either. Is there any other card you know works that you can try in, say, slot 1 with slot 2-5 empty? Is the winmodem a pci card? Does it actually work, or just detect? It could be that the whole pci part of the board is dead. Might be a blown cap.
The noacpi thing wouldn't matter. I made the suggestion on a hunch, before I found out that mb does not use the via bridge for audio, unlike mine...

Look again - see downloads. You might need a fully featured browser to move through the site though.
- looks like your c-media audio chipset is the correct one
- might need to use/force apic? (I guess you've already checked for irq conflicts, etc)
- you can use a dos bootdisk to flash your bios
Posted by curaga on May 27 2008,11:54Here's a dos bootdisk from bootdisk.com, in case you don't have one:

Posted by mikshaw on June 14 2008,23:31Although I'm not certain this was the probem, it seems to be simply a matter of removing "noacpi" from my boot options. I'd made some changes to the bios, reset the bios, and made a couple more changes, so I can't be 100% positive. In any case, I now have audio using my pci soundblaster.
I was hesitant to upgrade the bios because the upgrade path is apparently very dependent on the current bios version, and I couldn't find the version number for mine.
Thanks to all for taking the time to help.
EDIT: there seems to be some serious jumping now, both with audio and video files....I'll have to look into it again later.
