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?
What I am looking for is to have system wide implementation of sound enhancements like bass boosts, echoes, Fidelity, Stereo enhancement and so on.
Audio Video players have their own equalizer but they enhance only the audio / video files they are playing.
So to enhance sounds playing such as: YouTube, Spotify, System Sound, etc. I need a enhancer software. Back in Windows, I used to use SRS HD audio lab to do the same.
P.S. I have a horrible Speaker set.
Is it possible to do realtime noise-removal with PulseAudio, so the sound output that's coming out is smoother?
Sometimes the pulseaudio service stops and it doesn't restart itself when I open an audio file with banshee or totem.
How I can make pulseaudio start again without having to logout?
Ubuntu's desktop gui is great for changing audio settings (System->Preferences->Sound), like the default input/output device and setting the volume.
However, I would like to be able to do these things from the command-line. What tool is the gui using behind the scenes?
