Connecting the analog audio of the RPi (1B) to my receiver causes the receiver&#x27;s CPU to slow down to the point where it is unusable! It looks like the RPi puts out a DC-biased signal, and the receiver is seriously lacking input robustness. The two devices were also connected via HDMI, ruling out ground issues.<p>I&#x27;ve since moved the music setup to also use HDMI (the DAC in the receiver is bound to be better anyway), but sheesh, be warned.
