Alsa update in mainline broke ATI-IXP sound driver

Alsa update in mainline broke ATI-IXP sound driver

[Andi Kleen]

Since I updated an ATI x86-64 box to 2.6.17-git6 sound doesn't work anymore.

I just get

ALSA lib confmisc.c:672:(snd_func_card_driver) cannot find card '0'
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_card_driver returned error: No such device

ALSA lib conf.c:3962:(snd_config_expand) Evaluate error: No such device
ALSA lib pcm.c:2099:(snd_pcm_open_noupdate) Unknown PCM default

no matter how often I try. OSS clients also don't seem to work.
(in older kernels it sometimes didn't work on first try after boot, now it doesn't work 
at all)

The module loaded ok:

I can't find any output from alsa in the kernel log except for

First check /proc/asound/cards after loading snd-atiixp.  If the ATI
IXP entry appears, the device was initialized and set up.  If not,
something wrong in the driver initialization.

Then check whether /dev/snd/controlC0 exists.  If not, it's likely a
udev thingy.  Possibly upgrading udev package might help...

I'll defer testing because -git9 broke SATA too until after that is fixed.

Checking it now. There is no /proc/asound.

First /proc/asound appeared now - in the first try the modules weren't correctly loaded.
The card is shown there

 0 [IXP            ]: ATIIXP - ATI IXP
                      ATI IXP rev 0 with ALC658D at 0xfe029000, irq 217


I added some instrumentation to the driver now and the probe function seems
to run completely - at least it hits its return 0.

The device file is also still there so I don't think udev is to blame.

OK, and still you get the same error like:

	ALSA lib confmisc.c:672:(snd_func_card_driver) cannot find card '0'
	...
??

Any change if you set CONFIG_SND_DYNAMIC_MINORS=y ?

Yes.

With that it finally works. Thanks.

Still can it be fixed?

Well, the bug shall be fixed :)

Unfortunately I cannot reproduce this on my systems that are all based
on SUSE 10.1, and the latest 2.6.17-git works fine even
CONFIG_SND_DYNAMIC_MINORS=n as far as I've tested.

Could you check the strace and what open error occurs?
I suppose it's /dev/snd/controlC0, but don't figure out exactly.


thanks,

Takashi

Sorry for the delay

(as root) I get

5184  open("/dev/snd/controlC0", O_RDONLY) = -1 EACCES (Permission denied)
5184  open("/dev/snd/controlC1", O_RDONLY) = -1 EACCES (Permission denied)
... (upto 31) ...
5184  open("/dev/sound/dsp", O_WRONLY|O_NONBLOCK) = -1 ENOENT (No such file or d
5184  open("/dev/dsp", O_WRONLY|O_NONBLOCK) = -1 EACCES (Permission denied)

ccontrol0 is
crw-------  1 andi audio 116, 6 2006-06-29 11:49 /dev/snd/controlC0

It also doesn't work as andi

I stuck printks to the EACCES in sound/* and they don't trigger so it must
be somewhere else.
