[pulseaudio-discuss] 0.9.22 on Ubuntu Lucid gobbling up CPU

[Brian J. Murrell]

I was so hoping that the PA on Ubuntu Lucid was going to be much more stable 
than previous releases but alas, I don't think it's to be.  Currently installed 
on a machine here is 0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu14 which 
presumably is some form of 0.9.22.

I have it currently running with "-vvvv" due to the instability and desire to
at least log what it's doing.  As such, I can provide a full log upon request.

But currently, at this moment, there is not even any audio running through it 
and it's using 90% of a pretty modern (and hence, somewhat beefy) processor.

The only thing the log is showing currently, while this is happening:

D: module-rtp-recv.c: Checking for dead streams ...

The hardware in this machine is:

$ lspci | grep -i audio

Definition Audio Controller) (rev 10)

Again, a full log is available if desired.

Thots?
