After updating to Version 2.5 I am having problems with the audio. It appears to be related to the digital output from the TV to my Bose home theater system. Audio will play from the TV speakers but not the Bose system on some files, mostly MP4 files, when actually viewing film. The strange thing is all files appear to play through Bose system when in preview screen. This problem developed after upgrading to Version 2.5 as all files played previously. Additionally, music files play through Bose system without a problems.
