Mame games fail to load after change to USB audio

Jakerz

Games launch and run fine but after switching to USB audio with this command:

pcm.!default {
type hw card 1
}
ctl.!default {
type hw card 1
}

The games no longer load. But other games & audio work fine.
Just Mame fails.
Thanks in Advance

Using Pi Zero
Retropie 4.2
Clean install

@Jakerz Which mame ? We ship with about 6 mame emulators.

Jakerz

just dumping the roms in the default "mame4all" directory

@Jakerz Yes but what roms? You need the correct romset to match the mame emulator of your choice, in the case of MAME4ALL, it's 0.37b5.

Mame4all-pi and USB audio have had long-standing issues so I don't think the rom matters. Here are a couple of possible solutions you could try:

Let me know how you get on as I am thinking of geting a USB sound card.

I will give those a shot, it's weird, the mame games will launch fine before changing to USB audio. But as soon as I change it, they fail to launch. It just goes back to the main menu. NES and others work fine with USB audio. I will keep trouble shooting.

you ever get this working? I am having the same problem

Coin Junkie

Having the same problem exactly. Anyone find a solution?

If you're still using mame4all, then I don't think there's a solution - it's a known problem and since there's no new development is happening for this emulator, it's unlikely it got fixed. I think there was a recent topic with the same symptoms for the latest RetroPie version.

Otherwise, please open a new topic instead of bumping a 3 years old topic, and add some info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
