EXEC error

[antoniomch]

I've downloaded a sourceforge project called AJAXMIXER available HERE

But it didn't work.

 

I found here was the error, but I do not know the cause..

The error is in this function:

	private function _exec ($card, $args) {
		array_unshift($args, $this->_amixer, '-c', $card);
		exec(implode(' ', array_map('escapeshellarg', $args)), $output, $return);
		if ($return != 0)
			throw new Exception('Amixer returned an error. Maybe your webuser isnt in the audio group?');
		return $output;
	}

 

The command that is executed seams to be well built, but the function returns 1, and throws an exception..

Path are ok too.
