Thanks I really enjoyed this episode. I actually do something similar with one of my Raspberry Pis but I use Jezra's muttonchop audio server (https://www.jezra.net/projects/muttonchop) and control the audio either from my phone, tablet, or laptop. Mutton-chop has a web interface so you just need a browser on your remote device to control everything. I hook the Pi into a 1972 Marantz receiver. Like you, I found that I needed to get a USB audio interface b/c onboard audio was awful. I got a little dongle off of Amazon for about 8 or $10 and it sounds tremendous. Incidentally one of my favorite streaming stations is JazzStream: Capitol Public Radio (Sacramento)
