Hmm, it seems unlikely that overriding the headphone would lead to working speakers, but assuming that you have double-checked and verified that this is actually what's causing it to work:
The only thing that could remotely have any effect and that's different between images 2 and 4 is the channel group, but it's difficult to tell why without looking more closely at the kernel source code. Btw, are you currently having the DKMS upgrade installed, or not? Could you upload alsa-infos (see https://wiki.ubuntu.com/Audio/AlsaInfo ) for both the scenario where internal speakers do not work (but should), and where they actually work? We could then try looking for differences between them. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/960124 Title: [VPCZ13C5E, Realtek ALC889, Speaker, Internal] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/960124/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
