Very Computer

Hi,

I just upgraded to linux-2.4.6 and the latest ALSA driver from the CVS tree
(07/05/01) and found my sound system is no longer working.  I checked the
/var/log/messages file and found the following message:

        PCI: Found IRQ 10 for device 00:04.5
        ALSA card-via686a.c:241: codec_valid: codec 0 is not valid [0x980000]

Has anyone encountered such a problem with ALSA on a MOBO that has a
VIA686a chip?

TIA.

slightly off-topic, but why are you using the latest(bets) drivers?
alsa 0.5.1 works wery well...

sorry for being of no real help :)

the excession

Some of the audio/sound proggies require newer ALSA and the ALSA 0.5.1 does
not work.

ok, not i problem i've had so far, but give us more information and well
see what we can do about it.

for instance, what is your alsa configuration in etc/modules.conf?

what does lsmod say once the system is booted up?

what happends if you load the modules manually?

give enough info and well hopefully figure somthing out - tho if you're
using the beta, it could be a bug, but i'd wait to start bugging the
alsa guys. at least until you've excluded all other options.

if everything else fails, i'll turn on the onboard sound on my 686a mb,
and give the drivers a try. :) - i've got an sb live...

the excession - what's this proggie that wants the beta alsas?

Manually loading via686a module gives the following error messages:

My Linux system is an AMD Athlon 500MHz with Asus K7M Mobo, thus a via686a
sound system.

The only via686a sound my system has is on board.

Quote:> the excession - what's this proggie that wants the beta alsas?

it should not be snd-card-x, but snd-card-0.
cuz they are the options for the module of your soundcard. no wonder
modprobe sez u have a bad config...unless it's a typo from you?

so far so good, modules there, but your main is unused. see above?

there you go. i't either that "x" which should be "0", or bad irq/dma.
my via kt133 mb lets me set the stuff manually in the bios. check that
it's right?/modify the settings in modules.conf to match?

mine an athlon 800 thunderbird, via kt133, via 686a southbridge - sound
turned off - and sblive. but - as i've said - i can always turn it on
and check if I get the same problem :)

so, change that thing in your modules.conf. also, try turning off the joystick stuff,

as i've yet to see it work aniway :(

keep us posted, i f it still doesen't work, ill try it here.

the excession - getting the files right now...

belay that, it should be the exact name of the module you need - i
checked on mine and it says snd-card-emu10k1.

so yours should say snd-card-via686a

modify, run depmod -a
and loading the module again

the excession

It was not a typo and I made changes to it as you had suggested below;
however, the problem still presists and the /var/log/messages says:

        PCI: Found IRQ 10 for device 00:04.5
        ALSA ac97_codec.c:1388: AC'97 0:0 does not respond - RESET

(I don't know if that error messages will help).

right.

this might be a hardware/alsa problem/bug.

i'll try seeing what happends if I turn mine on and configure it.

ill ask again, do you _really_ need the 0.9.x betas? i've got 6 gigs of
the latest software installed, and found none that complains with 0.5.1...

while I do this - i have to shutdown, change a jumper, fiddle in the
bios etc... - see if the driver that comes with the kernel loads.
the one in 2.4.6 has midi support too. i'm not suggesting that you use
it instead of the alsa's, cuz' alsa has better sound quality, but at
least we'll know if its specific to the alsa drivers or a
systemwide/hardware problem.

let me know what happends with the kernel modules..

the excession

I believe it is a software problem, i.e. alsa-driver.  If I installed
alsa-driver 0.5.11 (back drop), I could use regulard audio software without
a problem.  However, someone has asked me to compile his audio program that
requires the beta version of alsa-driver, i.e. cvs tree.  I even tried
alsa-driver-0.9beta1 - alsa-driver-0.9beta5 to noavail.

Definitely...:(  Also, it is better to find out what the problem is with
the beta driver now than having such problems when the beta version becomes
a released one.

Is you Mobo Asus K7M?  Mine, K7M, does not have any jumper setup that I
know to fiddle with.  When I installed the v0.5.11, the via686a occupied
interrupt 10.  Now, when I install the beta version of alsa-driver from the
cvs source, checked the /proc/int, and found interrupt 10 is not occupied
at all.  Here is the cat /proc/int:

Did you mean patching the linux-2.4.6 kernel with the  
alsa-0.9.0beta4-k2.4.4-1342026.diff.bz2?  I have not touched the alsa
kernel patch since the alsa-0.9.0beta3-k2.4.3-1131131.diff.bz2.  I
remembered getting a lot of error with the patch and abandoned it since.

Quote:> the excession

right. i'm just back from dinner, ill try it out and if the problem
comes up on me too, we file a bug report.

agreed

a gigabyte GA-7ZX, via kt133 chipset, via 686a southbridge.
on mine there is a jumper that allows you to physically disable the
audio. which i had done, because the first bios revision did not allow
me to disable it otherwise. it's now enabled.

no, i meant trying the sound drivers that come with the vanilla linux
kernel. but since you say that the old alsas worked, then it's
definetely an asls problem. give , say half an hour, ill make a test
kernel and install the beta drivers on it, and report back.
then we can send mails to the alsa developers, since this appears to be
a bug.

be back soon.

what does lspci say?

forget it.

the beta are way tooo beta.

nothing works.
