I just updated my system and went out for a test sail. Now all sorts of weird stuff is happening that I can't figure out, so would appreciate any suggestions:
1) In OpenCPN the sounds play through the headphones instead of HDMI. I do hear the opening chimes, and my VLC plays fine, but in OpenCPN when I try to test a sound, eg SART alarm, it plays through the headphones instead of HDMI. How do I set it to send the output to the right channel?
2) my Own Ship icon dances around in direction. The COG predictor line is fine, as is the track it is laying down, but the boat's heading points off in all sorts of directions.
3) When I lay in a route, the direction to destination, every few seconds, shows something impossible, eg 2888576 (M) or 8 (T) and 337 (M) (WMM calculated magnetic variation here is - 15 deg) and then it goes back to a more normal number.
(sorry about the photo quality, don't know how to get a screenshot from the RPI)
4) The NMEA debug window remains empty, so I cannot see what sentences are coming through.
(debug window is open, but no sentences in the empty box above the Filters dialog. BRG show 7 deg for both T and M.)
5) I am using a usb wireless keyboard. Every now and then the mouse freezes and I cannot get any action from the keypad. The navigation, however, continues to function. Then after several minutes it all comes back again. I try reseating the USB dongle, turning off and on the keyboard but nothing, except time, seems to wake it up. I also tried a different keyboard with the same result.
The NMEA data is coming from a Quark-Electric multiplexer from which it goes by USB cable to my raspberry pi running openPlotter Signal K and from there to OpenCPN. Power supply is 5v 3 amp. No little lightning icon shows up.
At the same time I have OpenCPN 5.2.0 running on my laptop receiving the same NMEA data by wifi from the Quark. It does not show any of this erratic behaviour.
So, any suggestions please?
thanks
