Hello all,
A bit of a puzzler to me. I have a nettop (LE 7.02) with a built-in spdif toslink and the keep audio device feature will work with my AV amp. For example, the DTS flag on the AV amp remains enabled when a movie is paused. However, when using a usb to spdif adapter (rasp pi 2 LE 7.02) the keep alive does not work so I lose so audio as the AV amp syncs to the audio track when a movie is taken off pause. This same issue is repeated when connecting the same usb to spdif adapter to the nettop. Strangely enough when passing the audio via my tv ( rasp pi 2 / nettop passthrough --> tv hdmi --> av amp toslink) the same issue is repeated. Is the interface between two interfaces (spdif/usb) causing the keep alive to be lost or something else I can try? Sorry, I do not have an AV amp with HDMI connectors.
Thanks.
