[Elecraft] Sound Card Problems

[Lee Murrah]

I previously had a thread on problems I was having the internal sound card on FT8.  I was getting no output from the PC to the radio.  So thinking that the problem was how I had the internal sound card and WSJT-X set up, I switched back to using my SignaLink, which had worked perfectly before.  It worked fine for a while, but then the failed output problem returned. Mysteriously, it would start working again and then after a time fail again.

At one point I found that there were two USB Audio Codecs and the standard Realtek driver associated with the speaker settings.  I selected the one one not then i use, and the output returned. Then after another failure, I found that there was only one USB Audio Codec associated with the output.  

This morning I rebooted the computer with nothing connected and found only the Realtek driver.  I added the K3S USB cable, and one of the Codecs returned.  I added the SignaLink cable, and the second Codec returned.  By selecting the correct USB Codec, I was back in business.

So somehow the Codec driver for the SignaLink is getting changed or wiped out.  I assume that when I used the internal sound card, the wrong Codec was selected.

I hope this helps anyone else having similar problems. Any insights on how the CODEC is wiped out would be much appreciated.
