Most audio files are supported by Android, however occasionally there are factors that can cause an audio file to fail to play.
The easiest way to determine if there is a problem with the audio file is to long press on the media file and 'launch in external player'. This will load the media file and the Android music player. If it fails to play, then the audio file will not play in DoggCatcher because DoggCatcher uses an embedded Android music player for media playback.
In the past, audio failure have been caused by:
-Invalid audio encoding parameters - In this case it has been useful to contact the publisher and let them know. They will often try to correct the problem.
-Corrupt SD cards.
-Failing Android media player (or sound drivers). Rebooting the devices fixes this.
Some audio files are not encoded in a way that is compatible with variable speed. You can try disabling variable speed in the setting to determine if this is causing the problem. Note that setting the speed to 1.0x *is not* effective as testing for this problem.
Occasionally the Android media player dies in a way that can only be resolved by rebooting the device. If you get errors trying to play a variety of different audio files of which you are confident should work properly, try rebooting your device. Rebooting normally resolves this problem.
Switch to Google’s new Android experimental media player for 6.0+/7.0+ devices, it also includes a variable speed feature (DC Menu>Settings>Advanced) Enable “Experimental Marshmallow media player” the player can sometimes resume playback on an incorrect position, but the audio playback problems goes away.
