[Desktop-packages] [Bug 1783200] Re: [Lenovo Miix 310, Ubuntu 18.04] Audio no longer working

I'm also attaching the contents of /var/log/syslog for a desktop session with 'log-level = debug' in PA's daemon.conf file, if it helps. ** Attachment added: "syslog.pa.debug.xz" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1783200/+attachment/5168664/+files/syslog.pa.debug.xz

I can get other processes to produce core dumps, but pulseaudio is not producing any. Given PA stops dying when I add 'realtime-scheduling = no' to /etc/pulse/daemon.conf, this makes me think that the process is hitting either RLIMIT_RTTIME or RLIMIT_CPU, which would cause the kernel to send

I don't believe that'll work because pulseaudio is getting a SIGKILL, not a SIGABRT, , so apport will never receive a coredump anyway. I did a bit more research and came across . I updated /etc/pulse/daemon.conf, adding 'realtime-scheduling =

Yup, pulseaudio doesn't start at all. When I run it with 'pulseaudio -vv' to get the debug output, it ends with a SIGKILL. There's no daemon running. Here's a bug that I believe might be connected, and I commented on it before: https://bugs.launchpad.net/ubuntu/+source/alsa- driver/+bug/1759942

[Desktop-packages] [Bug 1783200] [NEW] [Lenovo Miix 310, Ubuntu 18.04] Audio no longer working

Public bug reported: I believe this is a pulseaudio regression, as the output of alsa-info (http://www.alsa- project.org/db/?f=730ab5b8f0499ef58c0e17f67f8f911ba53a011c) looks fine as far as I can see. I'm currently running Ubuntu 18.04, and I believe this is a regression as audio used to work

I believe I'm hitting the same issue, albeit with a Lenovo Miix 310, which previously to upgrading to Bionic had working audio. Attached is a log of what I get when I attempt to start pulseaudio with "pulseaudio -vv", and the list of devices and PCMs given by "aplay -l" and "aplay -L"
