[Elecraft] Macbook Pro, K3, FT 8 audio quits

[James Bennett]

Craig,

You are doing nothing wrong. Many folks have had this issue with Macs, including me. One way is to use a USB—>Thunderbolt adapter; it appears that several years ago Apple changed something in the way USB2 is handled in the OS and the result is audio occasionally getting sent to the internet speakers instead of the USB Audio CODEC. That adapter thing is how I resolved it on my MacBook Pro. Another way, and the one I use on my iMac that does not have a Thunderbolt port, is to bring up the MIDI application and set the USB Audio CODEC input and output to 44100 Hz instead of the recommended 48000 Hz. That has cured it for me and many others. You could also try that on your MacBook instead of using an adapter - up to you.I like the adapter method, as it frees up my USB port for other “stuff”.
