Should be fixed in the next build.

Hi - you can download an example wav that doesn't work from [url=http://www.johnmcculloch.net/downloads/NonWorkingWav.zip]here[/url]. The Output Plug-In doesn't seem to matter, MM4 just skips over the files that it cannot play. This happens on 2 different systems (Win 7 x64 & Win 2008 x64).

It's possible that the ones that don't work were ripped on iTunes and the few that do were ripped in MM4, though I'm not 100% sure. Oddly all these files play fine when rendered over UPnP to my Roberts radio.

Thanks
John

I cannot reproduce it. Could you upload me some sample file, that does not play? You can zip it and use mediafire.com. Thanks.
Is it the same for all output plugins?

Not sure which build this went wrong in, but somewhere between 1442, which works fine, and 1448 I seem to have lost my ability to play standard 44.1KHz 16-bit wavs as ripped from CDs. m4a files and 24-bit 48KHz wavs play fine, as do occasional examples of 16-bit wavs, but generally they don't. I've tried downgrading to 1442 and re-upgrading to 1448, but the problem is always there at 1448.
