---------------------------------------+-----------------------------------
 If MythMusic starts when the default audio is ALSA and if the device is in
 use by another process then snd_pcm_open can fail.  In this case
 AudioOutputBase::SetAudiotime can cause a divide by 0 exception because
 this->effdsp is 0.

 This patch checks the value of effdsp and avoids the division if it's 0.

 This bug & patch are also applicable to fixes/0.2[45]
