I have an audible hiss when when no content is playing but only when I am using the Toslink input through my S50 pro+. Content plays normally but when it stops then my speakers have a low level noise that is pretty annoying.
The sound is present even when i lower the volume of the S50 pro+ to 0
The hiss is not present when I am streaming through the S50 pro+ directly.
I use the S50 pro+ as a preamplifier for two channel audio when I am using my LG projector.
Please suggest possible solutions and reasons for the issue.
Nvidia shield connected to projector through HDMI
LG HF85LA projector connected to S50 pro+ through optical
S50 pro+ connected to emotiva Basx A2 power amplifier
Yes. I disconnected my arylic and bought a marantz nr1510 for my projector. I now only use the arylic for music with my vintage NEC integrated amplifier. weirdly I get no noise when it is used as a streamer
