Headless install on non-Raspbian SBC

[LostSoulfly]

I've been trying to figure this one out. I've installed multiple times, verified dependencies, etc.

/opt/Soundsync/soundsync_electron: error while loading shared libraries: libX11-xcb.so.1: cannot open shared object file: No such file or directory

This shows up in journalctl as well:

edit: Armbian 20.08.5 Focal with Linux 5.8.12-rockchip64

I have only tested Raspbian with the provided ARM package. It's possible your distribution doesn't include some packages that are included by default with Raspbian. If you already checked the deps with sudo apt-get install -f you can try to install the Chrome or Chromium package for your distribution. These packages have the majority of the same deps than what Electron (which Soundsync uses) requires.

[LostSoulfly]

I've tried multiple distributions for my SBC (Rock64): Ubuntu, debian, Armbian, DietPi as well as headless AND desktop versions of many of them, and am never able to get past this same error. I've installed all the recommended chromium libs (and Chromium opens fine..) Audio works in general both over HDMI and spdif, as well as through a USB DAC I have, but I can't ever get SoundSync to start. I've even tried compiling/running it with node unsuccessfully.

Any chance you could update the readme with some compiling instructions?

[geekuillaume]

To start Soundsync manually you need NodeJS and Git installed then clone this repo git clone https://github.com/geekuillaume/soundsync, install the deps npm install, build npm run build than start it npm run start. If you still have the problem, can you send me the logs generated by this command?

[LostSoulfly]

Thanks for the quick rundown!

I'm getting closer, slowly but surely..

installed nodejs..

curl -sL https://deb.nodesource.com/setup_14.x | bash -
apt-get install -y nodejs

Had to manually install yarn

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt update && sudo apt install yarn

The install process is failing because I didn't include a Arm64 version of audioworklet. I've just released a new version with this arch enabled. Can you try pulling and reinstalling the deps with yarn ?

[LostSoulfly]

It took some more work, but I got it to run!

I did another clone, installed typescript, manually installed webpack and the newest audioworklet, manually installed pulseaudio, did some other stuff..

[LostSoulfly]

Finally got around to testing it and I'm not able to send any audio to or receive from it. Looks like everything is sent/received out of order and is dropped. I never hear anything.

[geekuillaume]

It seems that the audio is not processed quickly enough to be sent to the audio device in the configured latency. I've implemented some optimizations today. Can you test it with the latest commit (bec36ff)?

[LostSoulfly]

Did a git pull then yarn then npm run build then npm run start. Sound source is my Windows 10 desktop with a Ryzen 3700X. This SBC is actually faster than a Pi 3, which is why this is so strange. I've also pulled up htop to show CPU and memory usage.

[geekuillaume]

I've found a bug related to the audio synchronization that could lead in silence. Can you again test the last commit ? Sorry for all this but I cannot reproduce the bug and it's way harder to pinpoint the source of the problem.

[LostSoulfly]

Just saw the commits and new version, already on it!

[LostSoulfly]

It works! You nailed it with that bug fix. I also tried to install the previous version from the deb package with the same x11 error, but at least I can build and run it manually.

Thanks and great work!

Here's the SBC I'm using: https://www.amazon.com/Iconikal-Rockchip-Computer-Processor-1866MHz/dp/B0868WSTXH

[geekuillaume]

Nice :) Does this work with electron (yarn run start:electron) ?

[LostSoulfly]

Yes, it does appear to work.

I can get you terminal access if you want to troubleshoot the deb package, just let me know.

edit: I also tried the auto-start option but it just launched an generic Electron window instead of SoundSync. I was able to get SoundSync to run at startup by changing the command in the .desktop file to yarn --cwd /path/to/soundsync run start:electron and it launched like a charm.

[LostSoulfly]

This needs more testing and it's probably got some redundant commands but I was able to get SoundSync running with some or all of this. I'm not sure if it will work all in one copy+paste, but it's definitely something for others to go off of when trying to run this on a headless install.

This was used on Armbian_20.08.1_Rock64_focal_legacy_4.4.213.img headless/server install.
If anyone has any input or additional commands to run please let me know!
