Problems identified in the AS

Hello everyone!

During a month of trial use, I identified three main problems in the application. If there are ideas and suggestions on how to resolve them, I would be grateful.

I am using a connection via upnp from a PC with an AS to an integrated amplifier Marantz M CR612.

  1. There is no possibility of fast rewinding on the track being played.
  2. Sometimes I select a track, start it, but playback can start after 10-20 seconds.
  3. After some listening time, something happens with the ability to adjust the volume from the remote control of the amplifier. After pressing the volume buttons, the volume level changes, but immediately returns to the starting point.

Thanks for the answers.
