That makes no sense. Start a mono game with no audio, do something that will cause it to make noise (start a game in BurgerTime, for instance), and hit Tab and go to the Audio Mixer.
Highlight the [default] 0 db and press forward-delete (Fn-Delete on a MacBook) and press C to add a channel mapping. Then press ] to move the cursor to the channel and use the left and right arrows to go through the channels available on your interface and see which ones play sound. (Also see if the channel names shown in the mixer line up with reality and the layout shown in Audio/MIDI Setup when you click Configure Speakers).

Ok I started BugerTime no audio at start. I "inserted coins, no audio. Press 1, to start game, no audio.
Went to audio mixer did the delete thing, add a channel mapping. Ok now there is audio. Then cycled through the channels, left, right etc.. the audio moved to each channel except for the center channel. No audio came out of it.
The channels names matched up except for two channels. In the Audio/Midi it has Back Left and Back Right while in MAME its listed as Rear Left and Rear Right. I don't think that makes any difference because that still worked.
Ok center channel is now getting audio. Weird..

BTW, if anyone with just regular 2-channel stereo stuff can try it out I'd appreciate that too. I don't expect any problems there at all, but it'd be nice to have some independent verification.

Thanks. I wonder what's with the center channel then. I'm not exactly sure but I think it might have something to do my usb external sound card. Generally it works fine.

I'm willing to try this out and help if someone can remind me how to download the latest build off git. The web site just shows 0.277.

To get the latest source to build, go to https://github.com/mamedev/mame and click the green "Code" button near the top of the page. There should be an option for "Download Zip" in the little window that pops up. Select that and you'll get a source .zip you can unpack and build.

I'm seeing a weird thing on Linux with 0.278. I have "volume -20" in my mame.ini for a very long time. Now I'm noticing that the first time I run a system that lacks a .cfg file, it always defaults to volume 0, but the next time I run the same system its volume -20. Same problem occurs if I run it from the command line "mame -volume -20" it's not respected until the .cfg gets written. I don't see anything specific about the volume being written to the .cfg. Here's an example of one that got created the first time I ran the system and had volume -20 in mame.ini. Looks like 0.278 might have a bug that expects a .cfg before it respects "-volume **" ?? <?xml version="1.0"?>
