Public bug reported: - I was unable to get any sound in Ubuntu when the kernel upgraded from default 2.6.32-21 -generic to 2.6.32-24-generic. - Alsa 1.0.21 was the default sound driver. - I followed the link : http://monespaceperso.org/blog-en/2010/05/02/upgrade-alsa-1-0-23-on-ubuntu-lucid-lynx-10-04/ and upgraded the sound driver. to 1.0.23 - Now i am facing intermittent sound outages (across reboots) and many times sound does not play at all. - There are a few instances when the sound plays properly, but when i plug my headphones in, sound stops playing. - i tried the sound-debugging wiki, but no use. hence reporting this issue.
-Also, strangely, in the link : http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt my sound card model is not listed :( #:~$ cat /proc/asound/card0/codec#* | grep Codec Codec: Realtek ID 665 #~$ Ubuntu version : #:~$ lsb_release -rd Description: Ubuntu 10.04.1 LTS Release: 10.04 ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: alsa-base 1.0.22.1+dfsg-0ubuntu3 ProcVersionSignature: Ubuntu 2.6.32-24.39-generic 2.6.32.15+drm33.5 Uname: Linux 2.6.32-24-generic i686 NonfreeKernelModules: fglrx wl AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
