It's not quite that simple. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1464757 points out that you still have to unmute the SPO channel in alsamixer to actually get sound. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1464757 Title: Audio broken on Dell Venue 11 Pro 7140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1464757/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1464757] Re: Audio broken on Dell Venue 11 Pro 7140
To check if the symptoms are actually identical to bug 1413446, there are a few ways to go about it debugging further. The easiest thing you can do is to grab kernel 4.2 (rc5 or later) which includes this commit: https://github.com/torvalds/linux/commit/ea7d521569a70418aa9f6309a1d1916709818b62 That avoids the behavior of the things changed by this _REV check. You'll probably need to cold boot a few times and might need to mess with mixers to get audio working after this. If that doesn't work properly then that likely means that there are other audio problems that need to debugged and it's not a BIOS issue or not only a BIOS issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1464757 Title: Audio broken on Dell Venue 11 Pro 7140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1464757/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1464757] Re: Audio broken on Dell Venue 11 Pro 7140
Ah, it seems I miss-read the BIOS issue that was going on with this model and then made a faulty assumption. Apparently the problem was not the A05 version in particular, but the flashing process in general.

GaryParr: I know Dell released an A05 BIOS for this model... but then pulled the BIOS after it caused problems. Would you have further information towards this (ex. support article on Dell's website noting this)? ...(I'm A04)... Just to advise, as per your Bug Description you are using BIOS A05 (not A04). Despite this, one thing that could be discussed with Dell as per your dmesg https://launchpadlibrarian.net/208945923/CurrentDmesg.txt : [0.076672] Your BIOS is broken and requested that x2apic be disabled. This will slightly decrease performance. Use 'intremap=no_x2apic_optout' to override BIOS request. Hence, at a minimum they either should provide an updated BIOS that fixes at least this issue, or if this was the problem introduced in A05, they should provide A04 via their website. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1464757 Title: Audio broken on Dell Venue 11 Pro 7140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1464757/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1464757] Re: Audio broken on Dell Venue 11 Pro 7140
Christopher, I haven't contacted Dell yet for a few reasons. The primary being that I'm not quite sure I understand what to tell them. From what I gather on the most likely related bug (1413446) the original issue was how the BIOS presented the sound card. But... I can't tell from the dmesg results if this is the same thing. It looks similar, but also different. Also, I know Dell released an A05 BIOS for this model (I'm A04) but then pulled the BIOS after it caused problems. Because of this, and because Dell doesn't officially support Linux on this model, I wanted to have some idea of what to tell/ask them before I raised the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1464757 Title: Audio broken on Dell Venue 11 Pro 7140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1464757/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1464757] Re: Audio broken on Dell Venue 11 Pro 7140
GaryParr, thank you for reporting this and helping make Ubuntu better. You have a slightly different revision (and different connecting hardware) than LP#1413446, so this highly correlates to it. Hence, given you have the latest BIOS for your model as per Dell's support website, have you contacted Dell and inquired about this from a BIOS perspective? ** Tags added: latest-bios-a05 ** Changed in: linux (Ubuntu) Importance: Undecided = Low ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1464757 Title: Audio broken on Dell Venue 11 Pro 7140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1464757/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
