Whenever I try to play an AC3 file (and I've tried multiple) on my Rockboxed iRiver H140, the unit freezes. I can then only reset via the reset button on the bottom. All other files (that I know of, mostly OGG Vorbis and MP3) play just fine. It didn't do this with the build I had from a few months (?) ago. (Sorry, I know it's aggravating and terribly unhelpful; but when I upgraded, I overwrote the old build, so I'm not certain what build the old one was or even when I got it.) I would attach one of the affected AC3s, but the smallest I have is a 3-4MB file.
I'm old to Rockbox but new to the Rockbox community, so I'm not certain as to what steps I should take in reporting this. Should I also post to Flyspray?
