dolphin emulator audio not working

netbsdnoob

Hello all I was tinkering with NetBSD 9.3 on a thinkpad t450s and i realized that audio is not working when i launch dolphin. Any idea why this could happen?
Can somebody help me?

"Not working" meaning it's silent, or is it glitchy somehow?

I see this MESSAGE for emulators/dolphin-emu that seems relevant: https://github.com/NetBSD/pkgsrc/blob/trunk/emulators/dolphin-emu/MESSAGE.NetBSD

Dolphin has several audio backend options in its audio settings menu.

* AOSound seems to stutter badly on NetBSD.
* ALSA seems best.

Install the audio/alsa-plugins-oss package, then add this to ~/.asoundrc:

pcm.!default {
	type oss
}

ctl.!default {
	type oss
}

IIRC there are similar issues with Dosbox, even. Emulation requires a LOT more resources than you might think!

Thanks a lot! I didn't know about this "MESSAGE" system, I will check that out now everytime!

Learned a new thing about pkgsrc.

Anyway I get the same issues described here:
https://forums.dolphin-emu.org/Thread-writerest-op-out-of-range?pid=383188
https://github.com/project-slippi/Ishiiruka/issues/160

I don't think this is related to audio, I had the same thing before applying the fix.
It's just that I was lucky enough to be able to lunch it a couple of times before.
Now it seems I have bad luck.

Any idea on this?
I am using pkgsrc 2022Q2 the version of the software is dolphin-emu nb28

The MESSAGEs should display automatically when you install packages... I'm surprised to see that you haven't encountered them yet.

Anyway, that GitHub thread talks about JIT compilation, so I would have recommended that you run paxctl +m on the Dolphin executable, but it seems that we've been taking care of that automatically already. https://github.com/NetBSD/pkgsrc/blob/trunk/emulators/dolphin-emu/Makefile#L43-L45

HOWEVER, pkgsrc doesn't use this 'project-slippy/Ishiiruka.git' version of the code. We're using the code at dolphin-emu/dolphin.git. I'm not sure what the relationship between the 2 codebases is, but my guess is that dolphin-emu/dolphin not having had a formal release since 2016 (!!) is what's motivated this "Ishiruuka" thing -- which had a new release just a couple of weeks ago.

I wonder if it makes sense for the emulators/dolphin-emu package to use the "Ishiiruka" code base going forward. I might even try to make a package for "Ishiiruka" and put it in wip and we could see if it makes a difference.

You might also try emulators/libretro-dolphin, or maybe what we really need is a wip/dolphin-emu-git which keeps track of the bleeding edge, since running the "development" and "beta" versions seems to be the norm for Dolphin. I know I use them when I run Dolphin on macOS and Windows. https://dolphin-emu.org/download/?ref=btn

dressupgeekout what is the difference between dolphin-emu and libretro-dolphin?

Two different emulators?

libretro-dolphin is a core for the RetroArch multi-system emulator frontend GUI thingy.

Super long story short: the version of Dolphin that has been made to integrate with RetroArch is not exactly the same one as the "vanilla" upstream version (github.com/dolphin-emu/dolphin.git). Therefore, it's worth trying out.
