Re: DINAH on PI Zero

 

I had this trouble quite a while back and I found the final thing to do after checking RF plug fitting, adding ferrites, checking earths and swr was to make sure the computer data/CAT cables from the radio were well away from any coax and never in parallel to them if they had to be close anytime.?

I agree some radios are more likely to be affected - but I've most only used Yaesu so never been a show stopping problem.

I was getting exact errors. RFI was causing the USB audio to disconnect.? Fixed it by separating the radio further, using some choked, etc, but also have a Fe-Pi clone (audio hat) enroute.? Are you using a USB audio dongle?

OK I have DINAH working smoothly on a Raspberry PI 3 running direwolf and all is working well.

I have now built from scratch on PI Zero? (PI3 compiles don't always work o PI Zero)? and I get the following errors:

Audio input device 0 error code -19: No such device
Audio input device 0 error code -77: File descriptor in bad state
Audio input device 0 error code -77: File descriptor in bad state
Could not open /dev/hidraw0 for write, errno=2

Terminating after audio input failure.

Direwoilf?is initially finding the DINAH as card 1 device 0.

aplay -l identifies the device.

alsamixer -c 1 can adjust sound level.

Thoughts?

Thanks!
