I'm using an Android device to stream video content to a Chromecast plugged into the back of an outdoor projector (Goodee) then I'm using the headphone jack 3.5 mm from the projector to a (nobsound) mini amp which is powering Polk atrium 4 speakers. The problem is that the sound level seems to be limited between the projector 3.5 mm output and the input to the amp I cannot seem to overcome this . the manifestation of this is that the sound level on *** some of the movies that were watching are too low. Some content streamed from Netflix had acceptable audio levels. Some content streamed from Disney+ or CBS all access had deficient audio levels. Appreciate all thoughts on this issue. Thx!!
