[Bug Report, but not really] RISC-V breakage; where do I go with this?
Bug Description
This is not really a bug - more of an imcompatibility.

root@riscboi ~ [SIGINT]# dpkg -l | grep libmpg123
ii libmpg123-0:riscv64 1.32.5-1+b1 riscv64 MPEG layer 1/2/3 audio decoder (shared library)
ii libmpg123-dev:riscv64 1.32.5-1+b1 riscv64 MPEG layer 1/2/3 audio decoder (development files)
Do you know where I should put this? LavaPlayer? This is using the fork with the updates to temporarily work around the playback issues.
Steps to Reproduce
Uh... Buy a RISC-V board, install Debian, install Java, make a SystemD unit, run the bot, observe?
# dpkg -l | grep jdk
ii openjdk-23-jre:riscv64 23~15ea-1 riscv64 OpenJDK Java runtime, using Hotspot JIT
ii openjdk-23-jre-headless:riscv64 23~15ea-1 riscv64 OpenJDK Java runtime, using Hotspot JIT (headless)
Jokes aside; bog-standard Linux install - but, doesn't really matter here.
Expected Result
Sound o.o
Debug Output
...should I? x)
Additional Info
VisionFive2, self-built 6.6.0 kernel, Debian Trixie. It's all over the place.
I know what I am doing; but my Java-fu is not so good - since, however, there is a likelyhood of Java devs peeking in here, might as well post this and see if I get a lovely pointer or not :)
Thanks and kind regards!
PS.: Migrating it back to ARM; got enough nodes. I hope the update with the Docker container comes soon, itching to put this into my Kubernetes cluster!
Checklist
- [X] I have looked for information about this within the documentation
- [X] I have searched for similar issues on the issues page
- [X] I am running the latest version of the bot:
As a workaround, do not use JMusicBot in a way which requires native libraries to function. JMusicBot makes use of native libraries under 2 circumstances:
- Setting a volume to anything other than 100 requires JMusicBot to re-encode the audio. It makes use of natives to do that.
- If JMusicBot encounters any non-Opus audio (such as MP3 or WAV) it will try to load native libraries to re-encode the audio to Opus. Discord only makes use of Opus for voice channels. (YouTube serves audio with Opus, so YouTube playback shouldn't be problematic. You'll likely just encounter that when trying to play local mp3/wav files.)
Unfortunately, no natives have been built for RISC-V, presumably as its still pretty niche. lavaplayer handles audio for us, so we'd have to ask them about this. I believe the developers are already aware of this incompatibility though.
Ahh interesting!
Thanks for the infos - thats the kinda pointer I needed. I wonder if I could "build" my way through this problem. Doesn't sound too difficult; just getting the natives built.
I'll come back to this when I tried some things out! :)
