Thank you for reporting this bug to Ubuntu. Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete -- 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/989847 Title: Problem between pulseaudio and ALSA, suddenly no sound Status in pulseaudio package in Ubuntu: Incomplete Bug description: After updating to 12.04, my sound was working fine. At some point within the past 24 hours, it very suddenly stopped working. I did execute an "apt-get upgrade" once, so this may have been the cause. I have not made any modifications to pulesaudio or ALSA's configuration, so Ubuntu's default configuration is set. I have been searching other bug reports with similar symptoms, but most of them are from back in 2008, so I assume this is a new issue. My sound card has only headphone output, so I must use headphones. % sudo lshw -C sound [sudo] password for ramin: *-multimedia description: Audio device product: 82801JD/DO (ICH10 Family) HD Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 02 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=snd_hda_intel latency=0 resources: irq:292 memory:fe6dc000-fe6dffff Symptoms: Pulseaudio works fine, I can use my laptop as a sink and hear sound played on my desktop (my desktop is the one with the problem). Alsamixer selects the correct sound card and I can unmute and turn-up the volume and PCM. When I fiddle with the volume in alsamixer, or in the Gnome Control Center, I can hear the usual white noise in my headphones become lounder and softer as I turn the volume up and down, so the alsamixer is certainly interfaced with the sound card. However, when I try to play a sound, either with aplay, paplay, or mplayer, nothing works. Although I was able to watch YouTube videos earlier today without any problems, I cannot remember if this was before or after I executed a software update. But when I sink audio output into my laptop, all three of these applications work correctly. One thing is curious: alsamixer has a "headphone" volume control right next to the "master" volume control, and the "headphone" volume control is unmuted, but I am unable to turn the volume up or down on this controller, it is fixed at a 0 value. I thought perhaps pulseaudio was trying to output to a non-existent port on the soundcard (like speakers instead of headphones), so I tried enabling simultaneous output, but this did not solve the problem. I tried executing "alsactl restore" and "alsactl init" but this did not solve the problem. I believe the problem may be with Pulseaudio, and how it has configured my sound card as a sink, but I am not sure. The sound card obviously is working (it was working earlier today), and so is Pulseaudio (it can sink sound into a networked sound card), but they don't seem to be "connected" together. Another possibility is that the sound card has not detected that my headphones are plugged in and has muted the output (although I can still hear the usual white noise when turning up the volume), but I don't know how to check for this with pacmd, and alsamixer is indicating that everything is UNmuted (except headphone output is fixed at 0 volume). PLEASE HELP!!! Here is the output of "pacmd dump" with my headphones plugged in: ### Configuration dump generated at Sat Apr 28 00:20:15 2012 load-module module-device-restore load-module module-stream-restore load-module module-card-restore load-module module-augment-properties load-module module-alsa-card device_id="0" name="pci-0000_00_1b.0" card_name="alsa_card.pci-0000_00_1b.0" namereg_fail=false tsched=yes ignore_dB=no deferred_volume=yes card_properties="module-udev-detect.discovered=1" load-module module-udev-detect load-module module-bluetooth-discover load-module module-esound-protocol-unix load-module module-native-protocol-unix load-module module-zeroconf-discover load-module module-gconf load-module module-default-device-restore load-module module-rescue-streams load-module module-always-sink load-module module-intended-roles load-module module-suspend-on-idle load-module module-console-kit load-module module-position-event-sounds load-module module-filter-heuristics load-module module-filter-apply load-module module-switch-on-port-available load-module module-cli-protocol-unix set-sink-volume alsa_output.pci-0000_00_1b.0.analog-stereo 0x7289 set-sink-mute alsa_output.pci-0000_00_1b.0.analog-stereo no suspend-sink alsa_output.pci-0000_00_1b.0.analog-stereo yes set-source-volume alsa_input.pci-0000_00_1b.0.analog-stereo 0x361a set-source-mute alsa_input.pci-0000_00_1b.0.analog-stereo no suspend-source alsa_input.pci-0000_00_1b.0.analog-stereo yes set-source-volume alsa_output.pci-0000_00_1b.0.analog-stereo.monitor 0x10000 set-source-mute alsa_output.pci-0000_00_1b.0.analog-stereo.monitor no suspend-source alsa_output.pci-0000_00_1b.0.analog-stereo.monitor yes set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-stereo+input :analog-stereo set-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo set-default-source alsa_input.pci-0000_00_1b.0.analog-stereo ### EOF ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: pulseaudio 1:1.1-0ubuntu15 ProcVersionSignature: Ubuntu 3.2.0-24.37-generic-pae 3.2.14 Uname: Linux 3.2.0-24-generic-pae i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
