Sound fails when changing the volume of snd_hda_intel (OK in 2.6.20-13)

Binary package hint: linux-image-2.6.20-14-generic

I'm using a Intel integrated sound card in a Samsung Q35 laptop.

lspci -v:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
        Subsystem: Samsung Electronics Co Ltd Unknown device c504
        Flags: bus master, fast devsel, latency 0, IRQ 22
        Memory at d8240000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable-
        Capabilities: [70] Express Unknown type IRQ 0

In 2.6.20.13 the sound works great (With options snd-hda-intel single_cmd=1 model=laptop-eapd added to /etc/modprobe.d/options) but in 2.6.20.14 the sound drops out when the master volume is altered at all. As far as I can see it can only be brought back by a restart.

I can confirm this on a Samsung R65 with almost the same lspci output.

Could these bugs be duplicates?

Still doesn't work with 2.6.20-15 ...

Here's a solution for this Problem:

"You need to be using http://adhd.irule.net/~crimsun/snd-hda-codec.ko and http://adhd.irule.net/~crimsun/snd-hda-intel.ko (sha1sums 30296823b2e995c4deafdc5dad21a1944b0704ad and d26c67c9d6d2f1177dfa36575c2150dc305359a1, respectively)."

here at my samsung Q35 it works..

On my Samsung Q35 this problem seems fixed as of kernel 2.6.20-16, see if it does the same for you. If it does, this bug should be closed together with its duplicate 116084.

Sound refuses to change at all on my Compaq presario C300 worked fine before i upgraded to gutsy....

Fixed upstream.
