OK, I tried the new kernel. Just as Jamin said, not only it doesn't solve the sound problem, it breaks the wireless card as well. Actually, with the new kernel, no sound device was detected on my machine at all! I'm attaching the Alsa-Info.
P.S I don't know if everyone is experiencing the same issue as mine. But mine seems to be an intemittent problem. For example right now, I DO have sound from my internal speaker, using the 3.5.0-17 kernel (a few minutes after boot). But sometimes I lose sound in a matter of seconds after logging in. ** Attachment added: "Alsa-Info from proposed kernel (3.5.0-18)" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1064621/+attachment/3418549/+files/alsa-info.txt.BPCPyJ67kT%20-%20Kernel%203.5.0-18 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1064621 Title: Internal speaker muted after a while, several Realtek codecs (Quantal) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1064621/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
