Public bug reported: After an update, I restarted my system only to find that the audio headphones were not working in latest kernel, 3.8.0-21-generic. I unplugged them and the integrated speakers were also not working. It's my first bug to report and I'm not sure how to do this. The bug is really similar to the stated here: http://askubuntu.com/q/294016/47254 and therefore similar (not sure if equal) to this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1169761
However, it has some differences: When I play anything anywhere, it just does not work. Not audio jack nor integrated speakers. I followed the instructions in that AskUbuntu question, choosing an older kernel through the GRUB and now the audio is working perfectly for me in the kernel 3.8.0-19-generic . In the newer ( 3.8.0-21-generic ) it would only list Dummy output in System Settings->Sound->Output->Play sound through, and not even the "Test sound" would work. I know this report is incomplete, please tell me which commands to run (to write the output here) to check the errors in a basic way. I will try with HDMI in a few hours when I get back home. Workaround: - Reboot and in GRUB select Advanced options (how to boot into grub: http://ubuntuforums.org/showthread.php?t=1565450) - Chose Ubuntu with older kernel Version: Ubuntu 13.04 Laptop model: Sony Vaio VPCEH13FX Audio: Intel® High Definition Audio (specs http://www.docs.sony.com/release/specs/VPCEH13FXL_mksp.pdf ) ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: audio raring ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1180925 Title: Audio not working in kernel 3.8.0-21-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1180925/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
