Hi Chris,
Some Debian users have been reporting that the lastfm player uses a
very large amount of CPU time. Some info in the forwarded message
below, and more at http://bugs.debian.org/354486
Please let me know if you have any ideas.
Thanks,
Paul.

Followup-For: Bug #354486
Hi,
I'm seeing this very high CPU usage too.
I recompiled with gprof turned on, and I see that most of the time is
being spent in sinc_process() from libsndfile.
Flat profile:
Each sample counts as 0.01 seconds.

time seconds seconds calls ms/call ms/call name

3.32 22.90 0.79 61776 0.01 0.01 synth_1to1
This appears to be being called from WaveThread::run()

Now considering sinc_process has a comment
> Beware all ye who dare pass this point. There be dragons here.
I'm not inclined to dive in there :) I CC'd Erik incase he knows of
anything that might cause this. I confirmed that the src_sinc.c file
is the same as the latest libsndfile download.
Of course, it's probably something stupid that WaveThread::run() is
doing to invoke sinc_process.
The only thing I can think is that this is on my laptop, a Pentium M.
I wonder if the other reporters are running similar hardware?
Thanks,
