Since upgrading the client app to version 2.009 the audio selection does not work anymore.
Independent of the audio selection always the first audio track within the MKV container is used. The issue seems to be related to the Samsung client as on other clients (Android, Web/Browser) the selection works as expected.
My settings are:
Hardware: BD-H6500 (2014 modell)
PMS: 22.214.171.12425-1bf24oa65 running on a QNAP NAS
