Hi all,
I'm trying to work around the lack of web audio on a Raspberry Pi +
Chromium project and have run into a bit of trouble: I need to play a
short sound when express responds to a route. The app is currently
running on node v0.6.19 & express 3.0.6.
If I run the aplay command (below) from bash, the sound card is
detected and the file is played. When run from the express route
handler, the sound card is not detected and no sound is played. (It's
the same user in both cases.)
I'm not sure where the issue is - any pointers would be most appreciated.
[-- example server.js starts --]
var server = require('express')()
, exec = require('child_process').exec
, util = require('util')
;
function puts(error, stdout, stderr) {
util.puts(stdout);
util.puts(stderr);
}
server.get('/sound', function(req, res) {
// env not sanitized for debugging purposes
exec("/usr/bin/aplay /tmp/testsound.wav"
, { cwd: process.env.pwd, env: process.env }
, function(error, stdout, stderr) {
puts(error, stdout, stderr);
res.send('ok');
});
});
server.listen(5151);
[-- example server.js ends --]
