Hello! I have now talked to upstream about this issue, and my patches have been applied. He also sent a third patch to enable EAPD on playback and disable it afterwards (for best power efficiency). If you can test his patch and confirm that it works, he will apply it to the 3.0 kernel and so it will be fixed in Oneiric. Can you please do that?
Test instructions: 1) Make sure no other workarounds (such as the manual hda-verb, dkms och alsa-drivers) 2) Download and install http://people.canonical.com/~diwic/temp/alsa-hda-dkms-acer3830tg_0.1_all.deb - this is a new version of the package, updated today. 3) Reboot and test. Thanks! I'm also attaching upstream's patch for reference. ** Changed in: alsa-driver (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/783582 Title: [Aspire 3830TG, Conexant ID 506c, Speaker, Internal] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/783582/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
