i think i have narrowed this down to a faulty RAM (in excess of 30K errors). I will replace this shortly and retest but that would explain why a new build and my other desktop with a similar build are unaffected, and why the error conditions are somewhat erratic.
Does it explain why the fault disappears when the speakers are plugged into the motherboard sound output versus the sound card though? -- 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/1673942 Title: pulseaudio suddenly stops. No dmesg entries. Nothing in the syslog Status in pulseaudio package in Ubuntu: New Bug description: this only happens when sound is through the PCI sound card. When i connect speakers to the motherboard output (I lose the 5.1 component), pulseaudio never dies. I have switched and replaced the sound card to no effect but I never really thought that was the issue. There seems to be no evidence of the failure unless I run it from the command line with -vvvv, when eventually I see a 'killed' message. The pulseaudio log collects initial messages, but nothing else is echoed to the log - which could be anything from 3-20 minutes [typically]. I'm more than happy to assist in getting whatever logs are required, but nothing I've seen documented seems to help. --- ApportVersion: 2.20.3-0ubuntu8.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC3: julie 30342 F.... pulseaudio /dev/snd/controlC1: julie 30342 F.... pulseaudio /dev/snd/controlC2: julie 30342 F.... pulseaudio /dev/snd/controlC0: julie 30342 F.... pulseaudio DistroRelease: Ubuntu 16.10 InstallationDate: Installed on 2015-05-19 (670 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) Package: pulseaudio 1:9.0-2ubuntu2.1 PackageArchitecture: amd64 ProcEnviron: LANGUAGE=en_NZ:en TERM=xterm-256color PATH=(custom, no user) LANG=en_NZ.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 4.2.0-30.36-generic 4.2.8-ckt3 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Home directory not accessible: Permission denied No PulseAudio daemon running, or not running as session daemon.
