Specifying an empty device path results in the first available codec and audio controller being used. The value

headphones plus speakers) as long as all the chosen outputs support the sound file format in use; if any do not then no

outside $-128$ dB to $+127$ dB (which are well beyond physically plausible volume levels) are not allowed.
