locked Re: Error In Sound Input #AudioIssues

Michael Ernst

Mike,I have addressed the RFI  topic previously,  but let me address it again. The error is occurring when I am not transmitting and have not been transmitting.So that eliminates RFI, other than any RFI being generated by Device power supplies. And furthermore, I have every USB cable and every wall wart cable wound around a Toroid. This issue is not RFI.Thanks, Mike, AE8USent from my T-Mobile 5G Device

If you are also receiving this error, I have two questions:1) Are you also using JTAlert, and have it set for sound alerts for such things as needed stations, etc.?2) Are you using USB speakers for the sound alerts, along with the USB Audio Codec in WSJT-X?I have discovered if I change the JTAlert settings sound card from the USB speakers to a non-USB audio device (in my case I am using a set of headphones), then the error goes away. I am still trying to determine if it is an error in the JTAlert software, or a conflict between the USB Audio Codec driver and the USB Speaker driver.  But I am almost certain, at least in my case that one of these is the culprit.Any feedback would be appreciated.Thanks and 73,Mike, AE8U
