[PATCH] libmyth: Avoid a divide by 0 exception in AudioOutputBase

Reported by: Lawrence Rust <lvr@…> Owned by: JYA
Priority: minor Milestone: unknown
Component: MythTV - Audio Output Version: Master Head
Severity: medium Keywords: divide zero exception
Cc: Ticket locked: no

Description

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]
