I have a turntable connected to my Play:5's line-in jack with an RCA to 3.5mm cable. The sound is great, but you can't have the lid close on the turntable when playing a full-sized LP -- meaning you can hear the audio faintly where the needle and vinyl meet. I've tried changing the line-in source name (e.g. home theater, computer) and I've changed the audio compression setting to uncompressed. But there's still a slight delay between the audio coming from the turntable and the sound coming out of the Play:5.
I imagine there has to be a way to get rid of that delay. It's incredibly distracting, to the point that I only enjoy listening to the audio on the turntable's built-in speaker -- which is far inferior to my Sonos! Is there anything else I can try, or is there a change you can make to the software that would remedy this problem?
