arm-firefox image crashing whenever a tab is trying to play audio on Oracle ARMv8 VPS

[meelunae]

Hello!

When trying to play videos on YouTube using the arm-firefox image on a VPS from Oracle's ARM free tier offering, the Firefox tab consistently crashes; the issue also reproduces when loading SoundCloud pages which made me guess the crash is audio related. I tried booting the image using the flag NEKO_DEBUG and the diagnostic logs seem to hint at a PulseAudio related crash.

My docker-compose is structured as below:

version: "3.4"
services:
  neko:
    image: "m1k1o/neko:arm-firefox"
    restart: "unless-stopped"
    shm_size: "12gb"
    ports:
      - "1993:8080"
      - "52000-52100:52000-52100/udp"
    environment:
      NEKO_SCREEN: 1920x1080@30
      NEKO_PASSWORD: redacted
      NEKO_PASSWORD_ADMIN: redacted
      NEKO_EPR: 52000-52100
      NEKO_ICELITE: 1
      NEKO_VP8: 'false'
      NEKO_VP9: 'false'
      NEKO_H264: 'true'
      NEKO_MAX_FPS: 30
      NEKO_OPUS: 'true'
      NEKO_DEBUG: 1

Is this a known issue? Upon searching in closed issues I've seen that m1k1o tested on an Oracle VPS, but I wasn't able to find any more mentions of this specific type of ARM machine (most issues are focused on Raspberry Pis)

Thank you very much for your support!

i tried your compose settings and remove NEKO_OPUS: 'true',and instead image: "m1k1o/neko:arm-firefox" of image: "ghcr.io/m1k1o/neko/arm-chromium:latest" ,i think everything is ok

[meelunae]

@lanmuz thank you very much for testing! I have tried the config provided by you and I get a black screen instead of the browser now. Could you share a dummy docker-compose file that I can use for testing? Maybe I'm missing something else! Thanks!

[lanmuz]

sure~ I use this

version: "3.4" services: neko: image: "ghcr.io/m1k1o/neko/arm-chromium:latest" restart: "unless-stopped" shm_size: "2gb" cap_add:

• SYS_ADMIN ports:
  • "8087:8080"
  • "52000-52100:52000-52100/udp" environment: NEKO_SCREEN: 720x450 NEKO_PASSWORD: a NEKO_PASSWORD_ADMIN: a NEKO_EPR: 52000-52100 NEKO_ICELITE: 1 NEKO_VP8: 'true' NEKO_VP9: 'false' NEKO_H264: 'false' NEKO_MAX_FPS: 10

and I installed in oralce arm aarch64 without gpu ubuntu 22.0 system.

this is my snap of use this setting can watch movies and can receive auido to my laptop and can hear,the video and audio is flash,i think every thing is fine and crashing/exit not happend
