I have a USB speaker attached to my Reaspberry Pi and am running OpenCPN
4.8 (OpenPlotter 0.17). The speaker works fine and sounds when OpenPlotter starts or when I select a .wav or .mp3 file. I can play sounds from YouTube for instance but I cannot get the alarm
to sound in OpenCPN
I select either of the two built in .wav files (which sound OK if I select them from file manager) and then press Test Alert Sound but I hear nothing. The card is defined in /etc/asound.conf as card 1. In OpenCPN I have tried Options>User Interface>Sound Device Index as -1, 0, 1 and 2 and none of them result in a sound being heard when I press Test Alert Sound (Tools>Options>AIS Targets).
Any ideas how I can make this work
? I don't have an AIS
connected at home but I expected the Test button to work
