WDTV LSMP Audio Problems with certain files

I’m having a similar issue with files that have worked flawlessly up until now. The audio is barely audible over an awful staticky noise. The issue is resolved if I turn the media player off, back on and hit play again for the same file. This has started in the last 2-3 weeks. Firmware is up to date, problem seems to happen with random avi files.
