Mine has everything commented out, except:

## Automatically appended by jack-audio-connection-kit
@jackuser - rtprio 20
@jackuser - memlock 4194304

## Automatically appended by jack-audio-connection-kit
@pulse-rt - rtprio 20
@pulse-rt - nice -20

I should add that pulse is not running.

I don't know if it's still relevant, but

libsndfile-1.0.17-6.fc10.x86_64

and here's what sh gen_setformat_c.sh says:
