sound issue after updating kernel

[amitvn]

last month installed kernel 2.6.38 and saw one problem with sound that whenever i use headphone mode in sound preferences
it doesn't mute the main speakers..
i thought might be problem of that kernel and now when i updated to lates 2.6.39 same problem persists........anybody having same issue??
For informatin when i boot back using default kernel i.e 2.6.37 all works fine

Have you tried running alsaconf (as root user) after you upgraded the kernel? See if that helps.

See also the blog post Nostalgia for those ALSA mixer channels that KMix and GNOME Volume Control used to have? for some tips that might be of interest.

after running alsaconf as root i get that no suupported PnP or PCI card found??
probe legacy ISA and cards?? This may make system unstable

What is your audio hardware? Run the commands lspci and lsusb as root user and post the results.

The other thing you can do is to stop the ALSA daemon before running alsaconf, then start it again afterwards:

Code: Select all

# /etc/init.d/alsasound stop
# alsaconf
# /etc/init.d/alsasound restart

no stoping the deamon didnt worked...shows the same message

running lspci :

and runnning lsusb

and lsusb showing 1.1 root hub and only one 2.0 root hub
wht does that means?

[amitvn]

looking at the only some working solutions at http://ubuntuforums.org/showthread.php?t=798945
if it would really works how should i determine which option i should include in configuration and basically there is no alsa-base.conf in my sytem but i have alsa.conf

[Fitzcarraldo]

Your audio hardware is reported as "Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01)". I'm surprised alsaconf doesn't see it; that would appear to indicate something is wrong, somewhere.

See the SL wiki article HOWTO: Resolve Problems with HDA-Intel Sound Cards.

If you enter the command lsmod as root user, which sound modules are listed?
