Daphne Sample Support
-
Are audio samples supported by the version of Daphne found in RetroPie? If so, where are they to be installed? Seeing as how the folder structure for installed games is very specific with this implementation, I'm guessing it's different than the standard PC version.

Well, the samples are actually included with the RetroPie install and are enabled as well as functional. An easy example of this can be heard when the rom to a game cannot be found and the 'saveme.wav' is invoked alongside an error screen. However, after further research, it appears as though the issue I am noticing is actually with emulated sound. For some reason, Daphne in RetroPie is ignoring the inherent sound clips of a game.
I installed the Windows version of Daphne to confirm this. I used 'Us vs. Them' as a test case and looked through the 'sounds' folder it installed for the necessary samples. Although they were not to be found here or in the RetroPie install, this can be explained a forum posting for the release of Daphne 0.99.7 that makes note that samples are not yet implemented for this particular game, leaving emulated sound as the only option.
Finally, I wanted to confirm that emulated sound was possible for this title, so I launched the game using the same files I use in RetroPie and the sounds were indeed present in the gameplay on both Windows and OSX. With no other forum posts existing here on this subject, I take it that this issue has yet to be noticed. Is this something that can be resolved in how the emulator is launched or is it somehow a deeper problem with how the emulator functions on the Pi?

Two things of interest to add. First, in searching for more information on this issue, I discovered that the Daphne source was patched for use in RetroPie by forum/team member @shmoopty, and I thought it might help to tag his name in this posting. Second is a listing of the
daphne_log_txtfrom just after running a game with this problem. Again I chose to use 'Us vs. Them' as an example.
