Is there another way to restart the sound system if pulseaudio/ALSA don't work?












130














I was listening to music, and my sound suddenly went dead in all my applications. I'm using Ubuntu 12.04, which uses pulseaudio, so I tried sudo /etc/init.d/pulseaudio restart, but nothing happened. According to lsof | grep pcm, nothing is using the soundcard at the moment, although I'm not entirely sure if my source for that command is applicable.



Is there a way another way to restart Ubuntu 12.04's sound system from the command line without rebooting the system?

I've used pulseaudio -k && sudo alsa force-reload a couple of times, and it worked well. The first part kills pulseaudio, the second reloads ALSA. You don't need to restart pulseaudio, because it auto-restarts.

    Sometimes you might need to clear pulse config with "rm -R ~/.pulse*" before issuing any restart.

    In my case there were nasty messages in kern.log / dmesg:



    sound hdaudioC0D2: HDMI: invalid ELD buf size -1


    The solution was simply to suspend and resume the machine!



    $ sudo pm-suspend

    Have you looked inside the folder to see if pulseaudio was available in init.d, try replacing pulse audio with alsa-utils
