I just received (today) a Raspberry Pi 4 and a pair of Klipsch R-51PM Active Powered Speakers to run off my Raspberry Pi 4. The R Pi recognizes the speakers, but no audio will come out of them. When I change where I am in a track of a song, the speakers make a very small static/pop noise, but not audio. I've tried every setting I can think of on the R Pi:
Volume Control = Hardware
Volume Control = Disabled / 0db
DSD over PM = Yes
DSD over PM = No
I tried hooking up two other powered USB speakers and they work absolutely fine (using Volume = Disabled / DSD over PM = No). Also, taking the advice from other forums, I tried switching the 2.0 USB (that came with the Klipsch speakers) over to R Pi's USB 3.0 ports -- still, I get nothing.
I'm going to reach out to Klipsch customer support, but figured I'd first add to this thread. If I find a fix I'll post it here.
