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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1464757 Title: Audio broken on Dell Venue 11 Pro 7140 Status in linux package in Ubuntu: Incomplete Bug description: Appears related to the following https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1413446 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1441852 https://bugzilla.redhat.com/show_bug.cgi?id=1194616 ubuntu-gnome@ubuntu-gnome:~$ dmesg -t | egrep "(audio|snd|INT3438)" dmar: ACPI device "INT3438:00" under DMAR at fed91000 as 00:13.0 snd_hda_intel 0000:00:03.0: enabling device (0000 -> 0002) sst-acpi INT3438:00: DesignWare DMA Controller, 8 channels haswell-pcm-audio haswell-pcm-audio: FW loaded, mailbox readback FW info: type 01, - version: 00.00, build 77, source commit id: 876ac6906f31a43b6772b23c7c983ce9dcb18a19 broadwell-audio broadwell-audio: ASoC: CODEC DAI rt286-aif1 not registered platform broadwell-audio: Driver broadwell-audio requests probe deferral ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: linux-image-3.19.0-15-generic 3.19.0-15.15 ProcVersionSignature: Ubuntu 3.19.0-15.15-generic 3.19.3 Uname: Linux 3.19.0-15-generic x86_64 ApportVersion: 2.17.2-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu-gnome 2440 F.... pulseaudio CasperVersion: 1.360 CurrentDesktop: GNOME Date: Fri Jun 12 19:33:45 2015 LiveMediaBuild: Ubuntu-GNOME 15.04 "Vivid Vervet" - Release amd64 (20150422) MachineType: Dell Inc.
