Yes ! it's a lot of time i tell this problem on canonical and nothing seems to be doing. Have you an HP Pavillon DV - or 7 ? It's seem to be a PC Pavillon HP DV problem. I change system and I load the new Quantal and.... NO SOUND !!!! I am in Quantal 64b (thinking that no problem else). Seems to be resolved on DV6 HP but not on DV7.
some infos on Forum Ubuntu EN : Problème son Ubuntu 12,04 idem 12,10 Quantal on PC Pavillon DV6 DV7, Shadow Mage (x-shadow-mage-x) wrote : #30 Hi, I would like to confirm that this bug appeared in 3.2.0-25 and was not an issue in 3.2.0-24. Myself and a number of other people are all experiencing this issue using an HP Pavilion DV6, as per this thread on Ubuntu Forums: http://ubuntuforums.org/showthread.php?p=12034674 Is it possible that this specifically affects HP Pavilion DV6 laptops (or perhaps other laptops as well with similar hardware)? If there is any additional information I can provide to help just let me know. Luis Henriques (henrix) wrote : #31 Ok, so if you're available to test a few kernels, we can try to find the commit on the 3.2.0-25 kernel that introduced the issue. We can start to bisect the kernel between the two tags (3.2.0-24 and 3.2.0-25) until we find it. I'll start building the first kernel. (By the way, you may also want to try the kernel currentely under -proposed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.)

In the meantime, I started analysing the commits introduced by 3.2.0-25.40 and found a "suspicious" commit: 73b3c06f83fbc43b02f1fe8aa770c37c3becb463: ALSA: hda/idt - Fix power-map for speaker-pins with some HP laptops So, I've built another test kernel, this time based on the original 3.2.0-25.40 but reverting this commit.

IAC, the kernel at http://people.canonical.com/~henrix/lp1013183/old/ (~lp1013183v2) *is* working for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1014866 Title: Matching subscriptions: No Audio after update kernel 3 2 025 in Ubuntu 12.04 32bits.
