[ecasound] problems with audioloops in ecasound 2.9.2

Using any audioloops causes garbled/distorted sound, and thousands of
error messages (see below). I am using ecasound 2.9.2 on Linux Mint. I
have also included the log file. I can hear the sound playing and
looping, but it's buzzy or distorted somehow, and the error messages
fill up Emacs. I'm using this through Ecasound.el. I would greatly
appreciate any help you can offer.
