Samples preview on Linux while using Jack Audio Connection Kit

[b1tfl0w]

The vscode-tidalcycles extension makes use of node-wav-player, which on Linux systems uses aplay for playing sounds, aplay is good for ALSA but if you are using jack it will throw an error: Failed to play the wav file. To solve this just open the file:
~/.vscode/extensions/tidalcycles.vscode-tidalcycles-1.4.1/node_modules/node-wav-player/lib/wav-player.js
and replace aplay in the linux part where it says this._proc = mSpawn('aplay', [path]); with mpv

		if (os === 'win32') {
			this._proc = mSpawn('powershell', [
				'-c',
				'(New-Object System.Media.SoundPlayer "' + path + '").PlaySync();'
			]);
			this._proc.stdin.end();
		} else if (os === 'darwin') {
			this._proc = mSpawn('afplay', [path]);
		} else if (os === 'linux') {
			this._proc = mSpawn('mpv', [path]);
		} else {
			reject(new Error('The wav file can not be played on this platform.'));
		}

of course you will have to install mpv player:
sudo apt install mpv
mpv will play fine with jack aswell in alsa, becouse it will automatically detect the audio backend in use.
