Fixing stuttering/high CPU mpd on Pogoplug

Recently got a special on pink pogoplugs, two at $12.95 each. My friend John also bought, and he clued me to the fact that these were labelled B01 on the outside, but were really E02 models as shown on the device itself.

I quickly had Debian Squeeze on the box using Jeff Doozan's script, then upgraded to Wheezy. Since I like to set up boxes as music players, I added mpd and mpc to the install.

I was listening to music in no time. However, there was a problem. My favorite classical music streaming station is KVOD from Denver, cpr.org. Of the five classical streams I had in my playlist, they were the only one to stutter every few seconds - the other stations played fine.

After hours of trying different things to fix the problem, I finally hit on a combination of factors that somebody had an answer to. I noticed that ONLY the problem stream showed high CPU in top, and also
had the stutter.

If you look in mpd.wikia.com/wiki/Tuning, you'll see references to samplerate. One suggestion was to change to:
samplerate_converter "internal"
I tried that and it immediately fixed the problem, at the cost of reduced sound quality.

There are other suggestions on the Tuning page, so check there for more detail.
