Is anybody working on support for playing ADPCM wave files under Wine? If not, I'd like to take a crack at it.
I have an app that I use (Delorme's AAA MapNGo 4.0) that uses ADPCM wave files to contain spoken information on attractions. I know that Wine can access my sound system to play normal PCM wave files, as MN4 also has speech synthesis that does work. However, any attempt to play a ADPCM file results in the program pausing for a length of time, then continuing. I infer that this is because the lower levels of Wine don't know how to handle ADPCM.
ADPCM isn't rocket science - several programs, including sox, understand the protocol.
So, is anybody working on this (outside of TG and Lindows)? Any (non-null) pointers to useful information on how Wine has put together the sound subsystem? I'm not a Windows programmer, I'm an embedded systems and DSP person, but if I can find a block of code to hook into I can make this happen.
Try --debugmsg +driver,+mmsys,+mci,+mmio,+mmtime,+mciwave,+msacm,+wave,+midi,+ mmaux,+relay (they're all inside dlls/winmm/*).
That should help a lot in finding what's missing.
