Sound issue in MAME
nitrogen_widget:
I never noticed any problem with sound on my rpi's. :dunno

Like I said, it may be personal preference, but there is plenty of info out on the RPi sites that explain and discuss the sound quality of the RPi. You don't have to use external audio, but it improved the audio on my setups and I plan on using them for all my projects based on personal experience. I am not using HDMI displays, nor HDMI sound. HDMI sound is good quality, but if the project uses analogue sound, external audio devices are an improvement.

Are you using Retropie or PiPlay?
I have used both without any issues. I just completed 2 more RPi setups (mini-cabs) using RPi version 2 boards with these USB sound cards and both Mame4all and Advmame work fine. I have been unable to get NEOGEO games to work at all on either Mame4all or Advmame. One of the ones I just built went to a buddy of mine who wanted only Mame emulation and wanted the Metal Slug series, but I was unable to get any of them to work. Here is a YT vid of the one I built for my friend: .

Thanks for the reply. :)
Like your mini machines
I am using Retropie with Emulationstation. Version 2.6 for Pi2.
Rather new to the Pi world and not sure what OS the Pi is running, Raspbian etc ????
I will copy a new image of Retropie onto my SD card and not do a software update to see if that makes any difference. Then change that line in the config file for the audio.
By the way I was getting NEOGEO Metal Slug working in the Noegeo emulator not the MAME ones. Was working well until I tried the USB Audio adapter :(
Cheers

The USB audio worked in 2.6 but I am using the 3.0 now. I did test mine again with Mame4all and it works. I am using Advmame on mine though. When you start with a fresh image, expand the filesystem first and load only a few mame roms and see that everything works there first, then do the USB audio change.
I am running Metal Slug in the Neogeo emulator also. Others have gotten it to work in mame, but I have yet to get it working.
I have discovered another quirk. I built two of those mini cabs and both are identical in construction and use the same SD card image. The one in the video plays Galaga 88 in Advmame with no issues, the sound is great and there is no stuttering. The one I built for myself stutters with Galaga 88. While trouble shooting, I plugged my video output into the one in the video and Galaga 88 works fine. Something with the display is screwing with my setup and they use the same LCD. I even tried another identical LCD and it still stutters. I am wondering if there is something slightly different with my RPi. Who knows. Everything else works great.

Hi,
I too am using a USB adapter and it works wonders.
"snd-usb-audio index=-2 to 0" is the only thing that needs changed to get it working.
If you're using mame4all-pi, you'll need the correct sample pack to go with the romset (0.37b5) in order to get fully working sound in a number of games. They belong in ~/RetroPie/roms/mame-samples.
Two others things I found that greatly improved sound using mame4all-pi (in dkong, for example) was the force-stereo option (I set it to yes, or 1, not sure of the exact 'syntax', in /opt/retropie/emulators/mame4all/mame.cfg, *I think*) and mildly overclocking the Pi itself (to 900 MHz, using raspi-config).
Even then, I find sound is still rather noisy for a number of roms. Must be due to the really old version number.
AdvMame and/or RetroArch and/or PiFBA may lead to a different experience. AdvMame, while theoretically slower, allows for newer roms. PiFBA also uses an updated, but smaller, romset. Neo Geo and a number of Capcom roms work better on PiFBA.
