hi Guys!
Maybe it is unrelated, but i have a somewhat similar issue.
My movies (only the picture) is freezing usually and there is audio if OMXplayer acceleration is OFF. If i turn that on, then i’m losing the audio on my mkv (probably DTS) files.
I’m not using any passthrough, the 8-bit dts hd… is enabled, etc… basically i’m just using default values in the Audio section.
More details (log and debug files are here), hope it helps narrowing down the issue: Freezing Video after July update - #9 by a1840317
P.S.
This has started to happen only with the 2015.07-1 (latest) update.
