Bug Description
Hi,
I have intel HDA PCH chipset, audio stops during a flash video is running eg. on youtube and then i cannot run any audio at all on any programme until i reboot system. This has been a persistent problem since i installed 4 weeks ago.
I have ubuntu. Alsa module is likely picking up the intel chipset correctly.
Thats the lscpi (audio)

First, run this command to gather information:
apport-collect 1133132
Next, if you can reproduce the issue, make a verbose pulseaudio log /wiki.ubuntu. com/PulseAudio/ Log

Finally, instead of rebooting after losing sound, try reloading alsa instead:
sudo alsa force-reload
