module_init fails with OEM SoundBlaster Live!

module_init fails with OEM SoundBlaster Live!

[Peter Chapman]

I have an SBLive! which came with a Dell Dimension PC. The snd-emu10k1
module has been refusing to load ("EMU10K1/Audigy soundcard not found or
device busy"), however I found the following patch makes it work:

By no coincidence I'm sure, I never got the spdif output on the card to
work. Perhaps it's a cut-down OEM version? I noticed a DELL OEM entry in
snd_emu10k1_ids[], but my card does not match that device id. Here is
the lspci output:

could a failure to add the spdif control be made non-fatal perhaps?

most likely your ac97 codec chip has the IEC958 control, which
conflicts with the native emu10k1's control.
please check /proc/asound/card0/ac97#0 (with your patch).

the one for DELL's board was addedd experimentally, but it got never
worked.  apparently it's totally different chip from emu10k1.

Is this what you mean?

I can't find any mention of IEC958, but then I don't really know what
I'm doing! I can check the chips on the card itself when I get home, if
that will help.

Thanks,
Pete

IEC958 is aka SPDIF.  you see it in the above too :)

does the board have spdif i/o?

Oh, I see! :) Yes, there is an spdif connector on the card, however I've
never managed to make it work, either under Linux or Windows. Not even
using Dell's own Windows drivers.
I've always suspected that I had a crippled version of the card from
Dell, but maybe it's just defective?
Personally, I'm happy to modify the source before I build it, but I
wonder if there are other people with the same hardware. I suppose time
will tell as 2.6.0 bings a whole load more alsa users.

no idea.  but you can try the attached patch.
it disables the ac97's spdif control but it still keeps the emu10k1's
one.  if you have an spdif receiver, give it a try.

Takashi, your patch lets me load the emu10k1 module. For me that's the
most important thing. My spdif output is still dead, though (my minidisc
keeps saying "no signal" even when I enable the control with alsamixer).
The card doesn't have an spdif receiver.
Thanks again,

Pete

what happens if you use "spdif" (or "iec958") pcm, e.g. aplay with
-Dspdif option?

The 0x1102:0x0002 is a standard emu10k1 chip, and not the cut down version.

If it was a 0x1102:0x0006, it would be the really strange dell one, so 
this one is just a bit strange!

We could use the emu->serial or Subsystem Vendor ID to use to identify 
this card, and create a special case for it.

Cheers
James
