MumbleLink not linking with Mumble on Linux. about fabric-mumblelink-mod

Can you clone this repo https://github.com/magneticflux-/java-mumble-link and run ./gradlew test and show the full log? You'll need a version of the JDK on your path variable.

[magneticflux-]

You have to enable "Link to game and transmit position" in Mumble.

I already did, as well as the option in audio output

You cloned this repo, which doesn't have any tests (it's just a wrapper for Minecraft). Clone the one I linked above which does tests for shared memory.

[w3bb]

@magneticflux- Oh sorry, I completely missed the java part of the URL, hold on

[magneticflux-]

Also, can you show the output of uname -a?

[w3bb]

https://hastebin.com/raw/duyusudeso

Linux jumping 5.8.18_1 #1 SMP Sun Nov 1 14:25:13 UTC 2020 x86_64 GNU/Linux

And just for sanity's sake, here's the options set in Mumble:

[magneticflux-]

Can you run ipcs -a and cat /proc/sysvipc/shm while you're connected to a server in Mumble and in Minecraft and show the output?

In the same way, can you run ls /dev/shm lsof /dev/shm while everything is connected? (lsof might need a package installed)

[w3bb]

[webb@jumping ~]$ ls /dev/shm
MumbleLink.1000 jack_db

I've double-checked the code and my implementation exactly mimics the implementation in Mumble's code.

My code: https://github.com/magneticflux-/jvm-shared-memory/blob/6b17a5bf925e56093720c413e448bb91ee08102d/src/main/java/com/skaggsm/sharedmemory/posix/SharedMemoryPOSIX.java#L32

Mumble code: https://github.com/mumble-voip/mumble/blob/3d7f8cc4e5f502652f6660822eb791cec79a61f7/plugins/link/link-posix.cpp#L141

The logs you gave indicate that my code is correctly opening up the shared memory object called "MumbleLink.1000" (1000 being your UID). Mumble hasn't opened anything. Is Mumble running as the same user? What version of Mumble are you using?

The relevant part of the log:

COMMAND     PID USER   FD   TYPE DEVICE SIZE/OFF    NODE NAME
java      19830 webb  mem    REG   0,23    10580 2729322 /dev/shm/MumbleLink.1000

Also, is the "Link v1.2.0" plugin enabled in the plugins list?

[w3bb]

So that probably explains that.

[magneticflux-]

Ah, something is very wrong with that! This is what it looks like on Windows:

[w3bb]

To be fair a lot of those are Windows-specific, but I'll probably need to bring it up with the Void maintainers. Thank you for the help.

[magneticflux-]

No problem, glad we figured this out!

[w3bb]

@magneticflux- I'm testing, and it doesn't seem to be working. Neither of us can hear a difference. Should I refetch my shared memory stuff again?

[w3bb]

I got the link plugin enabled, and it reports in chat that it's enabled. I just double checked his settings were correct.

[w3bb]

(It's entirely possible that it's a Mumble issue)

[magneticflux-]

You also might have to adjust the positional audio settings in Mumble. Try checking the "headphones" box maybe?

Did this, still no effect. Is there some sort of indicator for positional audio because I don't see any.

[magneticflux-]

If it says Linked to "Minecraft MumbleLink Mod" in the Mumble chat it's working and receiving data, so there must be some misconfiguration of audio device output. Are you using mono-channel sound?

[w3bb]

Hmm, then yeah it's probably Mumble. I'll probably end up opening a bug report there. Thanks for the help as always.
