Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
module-alsa-sink's "control" argument causes segmentation fault
Status in pulseaudio package in Ubuntu:
Incomplete
Bug description:
Loading the pulseaudio module 'module-alsa-sink' with the "control"
argument causes pulseaudio to segfault on my system.
In /etc/pulse/default.pa find this line:
#load-module module-alsa-sink
and change it to this:
load-module module-alsa-sink control=Master
then restart pulseaudio by running these commands:
pulseaudio -k
pulseaudio --start
Notice that it prints this into the terminal.
E: [pulseaudio] main.c: Daemon startup failed.
Try starting pulseaudio itself in the terminal, and you see what's happening:
W: [pulseaudio] pid.c: Stale PID file, overwriting.
Segmentation fault (core dumped)
