I'm seeing this in a slightly different situation .. I'm running an xpra server which starts its own pulseaudio server; something to do with running Chrome and attempting to play video randomly results in everything in /dev/shm getting deleted, which leads the shm errors reported above.
I made sure to set RemoveIPC=no in /etc/systemd/logind.conf, but systemd does not seem to be the culprit. I've tried using auditd to see what is wiping the files, but nothing is showing. Did anyone ever make any headway with this? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1572493 Title: pulseaudio 8.0 drops connections after playing audio in a firejail Status in pulseaudio package in Ubuntu: Confirmed Bug description: After upgrading from Ubuntu 15.10 to 16.04 (pulseaudio 6 -> 8), I notice that my audio output stops working every few hours. When this happens, if I run pavucontrol, it seems to wait forever trying to connect to pulseaudio. Killing pulseaudio and starting it again fixes the problem for a little while. I don't think anything fancy is needed to cause a hang; usually, I'm just using Chrome. This never happened with pulseaudio 6 over hundreds of hours of use. I am using the default pulseaudio config files on an HP EliteBook 8460p, which has this audio sink: 1 sink(s) available. * index: 0 name: <alsa_output.pci-0000_00_1b.0.analog-stereo> driver: <module-alsa-card.c> flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY DYNAMIC_LATENCY state: IDLE suspend cause: priority: 9959 volume: front-left: 61870 / 94% / -1.50 dB, front-right: 61870 / 94% / -1.50 dB balance 0.00 base volume: 65536 / 100% / 0.00 dB volume steps: 65537 muted: no current latency: 38.86 ms max request: 6 KiB max rewind: 64 KiB monitor source: 0 sample spec: s16le 2ch 44100Hz channel map: front-left,front-right Stereo used by: 0 linked by: 1 configured latency: 40.00 ms; range is 0.50 .. 371.52 ms card: 1 <alsa_card.pci-0000_00_1b.0> module: 7 properties: alsa.resolution_bits = "16" device.api = "alsa" device.class = "sound" alsa.class = "generic" alsa.subclass = "generic-mix" alsa.name = "92HD81B1X5 Analog" alsa.id = "92HD81B1X5 Analog" alsa.subdevice = "0" alsa.subdevice_name = "subdevice #0" alsa.device = "0" alsa.card = "0" alsa.card_name = "HDA Intel PCH" alsa.long_card_name = "HDA Intel PCH at 0xd4520000 irq 40" alsa.driver_name = "snd_hda_intel" device.bus_path = "pci-0000:00:1b.0" sysfs.path = "/devices/pci0000:00/0000:00:1b.0/sound/card0" device.bus = "pci" device.vendor.id = "8086" device.vendor.name = "Intel Corporation" device.product.id = "1c20" device.product.name = "6 Series/C200 Series Chipset Family High Definition Audio Controller" device.form_factor = "internal" device.string = "front:0" device.buffering.buffer_size = "65536" device.buffering.fragment_size = "32768" device.access_mode = "mmap+timer" device.profile.name = "analog-stereo" device.profile.description = "Analog Stereo" device.description = "Built-in Audio Analog Stereo" alsa.mixer_name = "IDT 92HD81B1X5" alsa.components = "HDA:111d7605,103c3588,00100105 HDA:11c11040,103c3066,00100200" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" ports: analog-output-lineout: Line Out (priority 9900, latency offset 0 usec, available: no) properties: analog-output-speaker: Speakers (priority 10000, latency offset 0 usec, available: unknown) properties: device.icon_name = "audio-speakers" analog-output-headphones: Headphones (priority 9000, latency offset 0 usec, available: no) properties: device.icon_name = "audio-headphones" active port: <analog-output-speaker> # dpkg -l | grep pulse ii libpulse-mainloop-glib0:amd64 1:8.0-0ubuntu3 amd64 PulseAudio client libraries (glib support) ii libpulse0:amd64 1:8.0-0ubuntu3 amd64 PulseAudio client libraries ii libpulse0:i386 1:8.0-0ubuntu3 i386 PulseAudio client libraries ii libpulsedsp:amd64 1:8.0-0ubuntu3 amd64 PulseAudio OSS pre-load library ii pulseaudio 1:8.0-0ubuntu3 amd64 PulseAudio sound server ii pulseaudio-utils 1:8.0-0ubuntu3 amd64 Command line tools for the PulseAudio sound server # uname -a Linux laptop 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux # lsb_release -rd Description: Ubuntu 16.04 LTS Release: 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1572493/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
