Bugs,
I posted this in #207135 too (probably a dup?):
If you are getting high CPU usage from pulse, change the resample method in
/etc/pulse/daemon.conf to a less CPU intensive algorithm:
resample-method = src-sinc-fastest
See if this works for you. My CPU dropped from 2-5% CPU to pretty much

Thanks for the clarification Daniel. Is there any way we're able to
help?
My audio controller [1] consumes a lot of CPU too, if glitch-free usage
is disabled. In fact the whole system is nearly unusable when playing
sound or video (up to 60% CPU usage for pulse alone).

PulseAudio cannot currently switch between glitch-free (and not) without
an explicit (manual) default.pa reconfiguration and restart. Your
configuration (and mine) seems amenable to glitch-free usage, but a
great many other jaunty users have configurations that are not. Until

Find the line that loads module-hal-detect in /etc/pulse/default.pa, and
remove tsched=0 from the end of it, and restart pulseaudio with
pulseaudio -k; start-pulseaudio-x11. Do things settle down then? In
addition, once you make this change, do you get crackly/glitchy audio at
all?

Hey Luke,
Just tried your suggestion of removing the tsched=0 and then running
pulseaudio -k; start-pulseaudio-x11.
Did not have any luck (keeps saying daemon startup failed).
Anyway the log of what I did (minus the editing of the conf file) is
attached.
** Attachment added: lukecommands.txt
Ignore the last post (I did not read all of the output of the pulseaudio
-v -v) (I commented out the #tsched=0 and it tried to use that as an
argument).
Anyways testing your commands again now with the config file set right.

Luke that seems to have worked. No problems as of yet no crackling or
distortions of any kind and the cpu usage is down to a total of 3%.
What was that line telling pulse to do? (don't tell me pulse was
outputting through itself =S?).

Removing tsched=0 turned glitch-free playback on. It seems your card
driver/system cause pulse to use lots of CPU if glitch-free is disabled.

Luke thanks for you replies and help. Pulseaudio is running fine now
however:
Where do we take this bug from here? Do we just make sure that tsched=0
is not the default? Or do we try figure out why my system hates that
option?
Anyway here is the output of lshw -html for my affected system.
