Bug Description

I upgraded overnight from 8.10 to 9.04 and lost sound in the jump from 2.6.27-11 to 2.6.28-11. With the new kernel, I'm only getting the HDMI interface and my cx8800 audio chip on my pchdtv3000. When I boot into 2.6.27, `aplay -l` gives me this:

Firstly, you're using model=3stack-dig. Have you verified that it's
actually necessary for your codec & revision? Notably, why is the
model quirk missing in your 2.6.27 (custom) boot but present in your
2.6.28 (generic) boot?

Secondly - and we'll have to troubleshoot this once you've replied
regarding the former point - you may need to pass probe_mask=1 as a
module parameter to snd-hda-intel. However, this is a conditional step
based on your rationale for providing the above quirk in 2.6.28
(generic).

Machine is at home, but that quirk was there as I was testing to see if the model option had any effect (I tried a few, I just happened to be on the 3stack-dig model when I gave up and ran the alsa-info.sh to submit this bug). A completely unaltered load of snd-hda-intel still won't load the driver and shows the same info with only the HDMI interface loading, which is why I even noticed the issue in the first place.

Just FYI on the custom 2.6.27 kernel, I patched the SATA driver since I was having problems with the RAID5. It's otherwise directly from the Ubuntu sources and the Ubuntu generic kernel configuration otherwise, so I'm confident it's not affecting alsa in any way.

I will attempt the probe_mask=1 tonight and have since removed the 3stack-dig. I did so when booting back into the 2.6.27 kernel.

Thanks!

I take that back. Didn't need to go home to test it. Still only detecting the HDMI interface.

In my dmesg I get these errors relating to HDA:

Doing some more thinking... this is the dmesg output for the 2.6.28-11 kernel grepping for HDA:

myth@Wakko:~$ dmesg | grep -i HDA

[ 9.900669] HDA Intel 0000:01:05.1: setting latency timer to 64

In 2.6.27-11 the card has IRQ 16. hda_intel is trying to get IRQ 0 for the card, and sending out error -16... could those be connected? Why is it trying to pull IRQ 0? That should be reserved for the system timer, never even attempted. Seems like this is definitely a kernel issue of some sort, ALSA or something.

Looks like this guy is having a similar problem with his HP DV4:

I believe I'm seeign a similar problem. I have an ASUS M2A-VM HDMI. Things were working with 8.10, not so much with 9.04. Here's the relevant bits during boot:

Under 2.6.27-14, I was seeing the on-board SB card as well as the HDMI output.

pitabred -- I love the unintentional pun about my post to the alsa-dev list -- the name I go by is Guy (my middle name :-) I have an update on my issue. I cannot begin to remember exactly what I did, but I got sound working at one point. I can distinctly remember making the latest also-driver-snapshot source and typing make install-modules and on reboot having sound. But, alas, it is now gone again. I had some serious issues with grub (after upgrading to grub2 -- what a mistake) and the restore process involved a lot of package purges and reinstalls. That, of course, lost the alsa-driver modules. Just this evening I tried the make install-modules when I noticed I didn't have sound again. And I'm back where I was several weeks ago. No sound on the SB output. The HDMI is correctly found. The also-dev gurus think this is a kernel issue. So, like you I'm available for tshooting should anyone here think I can help. I have an HP dv4 laptop:

I have no idea, of course, why purging all the kernel images, then reinstalling the latest generic and remaking and make installing the latest alsa-driver-snapshot doesn't work.

UPDATE - now, I noticed serveral suggestions for startup kernel params on this and other posts and I tried two of them simultaneously and sound has returned!! One is "pci=noacpi" and the other was "pci=biosirq". Now, I enabled BOTH of them at the same time. Sound is now working. So, I don't know which of the two, fi only one of them, is responsible. May be both. But, with working sound, I'm not changing a thing :-)

Thanks for the tips, and they may work for other HP DV4 owners as a workaround, but they don't do anything for my machine. Something has still changed with snd_hda_intel between alsa 1.0.17 and 1.0.20 or kernel 2.6.27 and 2.6.28 (or both) that broke the proper PCI and/or IRQ grabbing on my machine.

Good news! I have the proposed repository enabled and just installed the 2.6.28-13-generic kernel, and it shows all my sound cards as being detected! I'm not in front of the machine so I can't actually check the speakers, but everything looks on the up and up from remotely here. I'll post if it really does work:

Being that 2.6.29 and 2.6.30 didn't work from the Karmic packages, it may just be a kernel configuration issue. Hope that helps someone who has been having the same problems.
