I mentioned this in another thread, but I suddenly have moved to a battery issue out of the blue. The cause? Pulseaudio consuming CPU like when the equalizer is running (16-18%), it even drops to 9-10% with headphones in. As normal, if _playing_ something. Which I'm not doing. I don't use the media player in general. There's no obvious reason why pulseaudio should run its equalizer.

SDL1.2 does a 10Hz tick even if your app is completely idle.

Ok there's definitely something fishy with pulseaudio.

As I mentioned above pulseaudio was spinning CPU like when it's equalizing something playing. Nothing was playing. Battery in 'low battery warning' mode this morning. I looked through all processes running. There was really no reason for pulseaudio eq being active.
So I killed pulseaudio. It then restarted, but now with normal CPU (i.e. idle).

I'll be keeping an eye on this. I bet my battery performance will now be back to normal (until pulseaudio acts up again). I'm not a media player user so I don't know what triggers pulseaudio misbehaviour.

It's not necessarily pulseaudio's fault. Any app opening a pulseaudio socket and not closing it/closing itself will cause that.

@javispedro: I'm not familiar with how pulseaudio works. If it's via a socket then it should be possible to figure out the offending process with netstat -p (or lsof, if it's available). I will try to check that out if/when this happens again. What I did though was to look for suspicious processes, which I couldn't find.

This one didn't return anything.

Run as root?
No need to run as root. Perhaps you have mistyped the commands or something? Lowercase "LSHAL" and | can be gotten from fn-ctrl. In case of mistyped commands, it should list the command before and after | separately and never include | in the error message.

Does that mean the wifi was still on? Even so why would it drain so fast.
You will get something like that listing even in offline mode. When you are connected, included will be:
"UP BROADCAST RUNNING"
The "UP" and "RUNNING" are key.

I don't know how to tell for certain if power is going to the wifi radio.

Separate the vertical bar with spaces on both sides.

That isn't required. It works both ways just fine.
