Raspberry Pi B
HiFi DAC PiCobber from Geekaroo
NAD C352 Amplifier
B&W 804 speakers
I installed the latest Volumio (1.5) and selected the HifiBerry I2S driver and software volume control. I left all of the other settings at the default. The sound coming out of my speakers is barely recognizable. It isn’t just occasional pops or dropouts but more like the sound is completely garbled. I tried airplay from my Macbook running Spotify and various mp3’s off of a USB stick all with the same results. I also tried the 3.5mm and RCA jacks from the PiCobber.
I switched back to “None” for the I2S driver and plugged the Pi’s analog audio out into the NAD. It sounded fine–at least as good as the Pi’s analog out ever sounds.
I am an experienced EE with a professional, temperature controlled, lead free soldering station and I inspected all my joints under a magnifying glass so I don’t think the soldering is the problem.
Any ideas what might be wrong? Is this a software configuration issue?
