Bug Description
New Toshiba P50-B, but no sound. "ubuntu-bug -s audio" said that PulseAudio was not configured to use the card I want output from (Built-In Audio - HDA Intel HDMI, but pavucontrol hasn't helped anyway (in pavucontrol, under Configuration tab, all options under Built-In Audio claim that they are unplugged [ 3 options say "Digital Stereo (HDMI) Output (unplugged)", 3 more options say "Digital Surround 5.1 (HDMI) output (unplugged)" and an "Off" option]).

Antonio Rodriguez, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https:/
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-
kernel-
where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-
This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-
kernel-
Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Thank you for the indications on how to test this. I installed two kernels from mainline, v3.19.0-rc1 and v3.18.1, and both have my sound working correctly. I'm going to remove v3.19.0-rc1 from this machine, as I'd prefer to use a kernel that's not a release candidate.
I have a question, however. Should I revert to my previous kernel (3.16.0-29), or can I keep v3.18.1 without any adverse effects?

status: | Incomplete → Confirmed |
Antonio Rodriguez, the upstream kernel is not supported in Ubuntu as outlined in https:/
If you want to use this going forward, please feel free to mark this Status Invalid.
However, if you would like to have this fix backported to a Ubuntu supported kernel, the next step is to fully reverse commit bisect from kernel 3.16 to 3.18.1 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https:/
Thank you for your understanding.

I've been going through the kernels and trying to determine what's going on, and a curious thing is happening.
If I use a kernel that fixes my sound (v3.18.1-vivid, for example), and then use my old kernel again (v3.16.7-ck2), sound still works. However, if I boot into Windows 8, then return to Ubuntu (v3.16.7-ck2), sound no longer works. I've tested v3.17.1-utopic and I still have no sound, so I'm considering it as a bug-exists kernel.
I'm currently downloading 3.18-rc2 to see if the bug is still present after purposefully losing my sound by booting into Windows 8. The download is going very slowly (close to 4 hours for a ~60MB file). Are there any additional mirrors for kernel images?

Antonio Rodriguez (taserian) wrote : | #37 |
I've located the bisect. Kernel v3.18-rc6 has the bug, but V3.18-rc7 seems to fix it. I've removed the previous tag
kernel-
, and added the tag
kernel-
as the earliest fixed kernel.
Is there a tag I should use to show that the bug exists up to 3.18-rc6? And another to show that the reverse bisect is complete?

Antonio Rodriguez, while you have made progress, finding adjacent kernel versions is not fully bisecting as noted in https:/
