Please add this machine to the list impacted: Malibal Veda P180HM , aka Clevo P180HM , aka Sager np8180 (other rebranded flavors of this model also exist). RealTek ALC892 internal speakers fail to show up in sound-settings; instead the not-plugged-in iec598 aka S/PDIF output becomes default-sink.
Using the workaround from comment#32 corrects the trouble for my hardware. I have composed a brief shell-script which I believe can be cut-n-pasted into the xterm, rather than having folks perform manual editing. Worked for me on 12.04.3 with all updates but I have only tested it on this one machine. David, or other canonical employee, if this looks useful you might consider pasting it into the intro at the top, or as an addendum to comment#32.

I installed 12.04 from LiveUSB a couple months ago, and had no audio-playback (except in the bootloader via grub's play- command) until I had updated to 12.04.2 -- after which I was able to hear the drum-sound at the login-screen that appears immediately after boot. However, once into the desktop, I was not able to accomplish playback. When I would open up sound-settings from the taskbar (aka "gnome- control-panel sound-nua" under the hood), the only listed internal speakers were S/PDIF output. The laptop does have an spdif-out-jack, but nothing was plugged into it. Clicking on most any of the buttons in sound-settings would cause the not-even-plugged-in spdif-out-jack to become the default audio-sink. So to be clear, I did not plug in external speakers or headphones or microphones -- there were no internal speakers in the list provided by sound-settings, from what I can tell (ever at any time). I believe following the instructions of step#1A over here helped -- https://help.ubuntu.com/community/SoundTroubleshootingProcedure -- because when I executed killall pulseaudio; rm -r ~/.config/pulse/* ; rm -r ~/.pulse* then counted to fifty then rebooted, I was able to achieve mp3 playback in rhythmbox. There were still no external speakers listed in sound-settings, and any time I messed with sound- settings it would change my default speakers from the (invisible to it) internal speakers to the spdif-out-jack, necessitating a reboot. From the instructions in this thread, I have determined that it is possible to perform pulseaudio -k , as opposed to rebooting, which corrects this particular problem reliably, at least. As previously mentioned, applying the tip from comment#32 fixes my problem -- I now see 'built-in audio' internal speakers within sound- settings. I also applied the microphone related workaround, although I do not know whether or not my box suffers from that difficulty (I do not use an external mic at the moment). While I was fiddling with trying to debug this vexing problem, I did find the following indicator which reliably told me when I had lost my default speakers, and switched over to outputting sound to the non- existent spdif-connected-hardware. When I first logged in, I would run this command: lsmod | grep -P "^snd_hda_intel" and then make a note of the UsedBy number in the third column, typically the numeral five. Once I lost my audio, due to fiddling with sound- settings, I would instead see numeral six (the spdif endpoint presumably). Running the killall workaround would put the number back at five where it was originally, and audio would work for a bit thereafter. p.s. This was a dastardly difficult problem to track down. There are a couple things I would suggest for David and/or some other Ubuntu employee with commit access, to help endusers over this hump. First of all, a simple fix, pleas list the audio-chipsets in this bug, not just the model-names of the computers. Clevo P180Hm w/ RealTek ALC892, in my particular hardware. Most forums recommend that you search for your audio-chipset, not for your model-and-vendor, but this bug does not show up thataway currently. Second, because in at least some cases (mine for one) the bug manifests itself as refusing to display valid information, it was difficult for me to figure out what was going on. It did not dawn on me that my sound- settings applet might be lying to me about what hardware was avaialble for output and input, until *quite* a lenghthy struggle had already passed. I realize that pushing functional changes into LTS releases is frowned upon, of course.... but as David's SRU points out, this is quite the maddening bug, which intermittently prevents listening to music, voice-chat, and other Gotta-Work-All-The-Time features. I'm suspicious that there are plenty of folks out there that *know* their audio is busted, and either change distros -- I ran across at least three such cases with just ALC892 hardware alone in the forums -- or live with the problem. My suggestion is this: push an update to gnome-control-panel (or whatever package contains the ubuntu sound-settings dialog-box), and modify one of the text-labels on the Output Tab and the Input Tab, to alert endusers there is a fix for their pain. Something quite brief, like the following, would suffice: Do not see your speakers? (with a hyperlink that takes them to this bug-report) Do not see your microphone? (again with the hyperlink) These would need to be translated, and verified to fit in the available pixel-real-estate of the dialogbox in question, but methinks it could be done without violating the spirit of an LTS release. Failing that, backporting David's 3.6 kernel fixes to the 3.5.0.41-series that is currently in use with 12.04.3 seems the only way to fix the root cause. In any case, thanks to David for his hard work, and thanks to others for helping me solve my local difficulties. Glad I finally have reliable audio. ** Attachment added: "output of script from alsa-project.org , with bug in play (audio-out going to unplugged-spdif-jack)" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/946232/+attachment/3856405/+files/alsaInfoWhenAudioPlaybackFailing.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/946232 Title: [Meta-bug] Missing speaker and/or internal mic port Status in “pulseaudio” package in Ubuntu: Fix Released Status in “pulseaudio” source package in Precise: Fix Released Bug description: ==== Read me first ==== If you're suffering from one of the following problems: 1) In the sound settings dialog, when you plug your headphones into the designated 3.5 mm jack, there is a "Headphones" device correctly shown, but when you unplug it, there is no "Speaker" device shown, even though you have internal speakers on your computer. 2) In the sound settings dialog, when you plug your external microphone into the designated 3.5 mm jack, there is a "Microphone" (or similar) device correctly shown, but when you unplug it, there is no "Internal Mic" device shown, even though you have an internal mic on your computer.

IF AND ONLY IF that is working for you, please attach alsa info (see https://wiki.ubuntu.com/Audio/AlsaInfo ) to this bug, together with the name of your machine (e g "Dell Latitude D620"). I'll try to include it in a list of devices that we have to manually enable and release it as an update to 12.04. Thanks! - and sorry for causing the bug in the first place :-/ // David Henningsson ==== The following machines are known to be affected (no more alsa-info needed) : # Acer AOA150 # Acer Aspire 4810TZ # Acer Aspire 1810TZ # Packard bell dot m/a # Acer AOD260, AO532h # Dell MXC051 # Dell Inspiron 6400 and E1505 # Dell Latitude D620 # Dell Latitude D820 # Dell Latitude D520 # Dell Latitude D420 # Dell Inspiron 1525 # Dell Inspiron 1011 # Dell XPS 14 (L401X) # Dell XPS 15 (L501X) # Dell XPS 15 (L502X) # Asus 904HA (1000H) # Asus T101MT # Sony Vaio VGN-SR21M # Sony Vaio VPC-W115XG # Fujitsu Lifebook S7110 # Fujitsu Lifebook A530 # Toshiba A200 # MSI X360 # Lenovo 3000 Y410 ==== ==== SRU Justification === First, sorry if this bug is a bit messy, but I think it would be even more messy if I spread the information across several bugs. Here's some explanation: The long-term fix is already in Quantal, because we backported the "Phantom Jack" support into Ubuntu's 3.5 kernel. Together with that comes a small PulseAudio patch, http://bazaar.launchpad.net/~ubuntu- audio-dev/pulseaudio/ubuntu.precise/revision/519/debian/patches/0624 -alsa-mixer-Add-Phantom-Jack-support.patch - the reason I want this in 12.04 is to provide a better experience for users running the quantal kernel on precise, i e, the backport kernel coming with 12.04.2. In addition to that, while doing an SRU I could just as well add a few more quirks for affected machines showing up after the previous SRU, so that is now done in http://bazaar.launchpad.net/~ubuntu-audio- dev/pulseaudio/ubuntu.precise/revision/520/debian/patches/0625-alsa- mixer-Add-a-few-more-machines-to-internal-mic-w.patch [Impact] Several laptops (see above list) are missing mostly internal mics, but sometimes also speakers in the Sound Settings / PulseAudio. This leads to an inability to control volume for these devices, and often not being able to use them at all. [Test Case] * Have an affected machine * Notice that when your mic is unplugged, the "internal mic" is correctly shown in the sound settings [Regression Potential] The quirk-style fix only affects the machines above. The long-term fix affects only users of a newer (quantal or later) kernel. ==== I have an DELL Inspiron 6400. As it seems ubuntu precise beta1 thinks it has a digital ouput. In the audio settings it says Play sound through: »Digital Output (S/PDIF)« As you can see there → http://support.dell.com/support/edocs/systems/ins6400/en/om/specs.htm#wp1054816 it has no S/PDIF output. The audio Settings doesn't let me change the mode. Sometime the system sets the mode to »Digital Stereo (IEC958) Output« but the drop-down list menu is grayed out so I can't change it. If I plug in and out my headphones the system changes the mode to »Analog Stereo Output« and I can hear Sound again. If you need more Information please let me know.
