Wait for the next build maybe? Pre-release development software is expected to break during development. If stability is important to you then it only makes sense that you should stay on 17.6 stable branch.
Gents,
Dolby Digital passthrough is still not working on OSCMC. However, the DTS HD MA is working fine.
Dolby Digital passthough has been / is working fine on Coreelec in the period since I first reported it, which sugests it may be an OSMC specific issue. Has this been looked at?
Live TV is not meant to support passthrough. CE have added a hack for this; but it’s not a good idea to include this anymore. We included it in Kodi v17 but it causes its own set of problems.
