Subject: 2.6.23 - MacMini - snd-hda-intel stopped working

Ubuntu kernel 2.6.22-10 works fine - I get sound although volume
control doesn't seem to work.

With 2.6.23 (today's git actually) I get this error on loading snd-hda-intel -

[ 672.830052] PCI: Setting latency timer of device 0000:00:1b.0 to 64
[ 673.061586] hda_codec: STAC922x, Apple subsys_id=106b0800
[ 673.471059] ACPI: PCI interrupt for device 0000:00:1b.0 disabled
[ 673.471367] HDA Intel: probe of 0000:00:1b.0 failed with error -16

Any ideas?

Thanks

Parag

It's a bug in post-2.6.23 merge, so 2.6.23 should work as is.
The fix was already in ALSA tree but still not pushed.

Jaroslav, pretty please prepare the push to Linus.


thanks,

Takashi

Not that this would help you a lot, but it worked with a stock 2.6.23 kernel
here:

2007-10-19_05:56:58.01014 kern.info: hda_codec: STAC922x, Apple
subsys_id=106b0800
2007-10-19_05:56:58.01015 kern.info: usblp0: USB Bidirectional printer
dev 11 if 0 alt 0 proto 2 vid 0x03F0 pid 0x6004

What model do you have? Mine is the first dual core version (1,66 GHz,
Superdrive)

I attached my kernel config, for the case that this makes any
difference.

Right. As was pointed in previous email the bug was introduced in post 2.6.23
updates (I was running git but Makefile version was still 2.6.23).

Looks like we have a fix that'll go to Linus shortly. I'll go back to released
2.6.23.1 for the time being.

Same model I have, BTW.

Thanks
