However recent sndiod versions allow "alternate devices" to be specified with a new -F options. If the alternate device is present, it's used. If it's disconnected, sndiod switches to the other one. In your example, if sndiod is started with: sndiod -f rsnd/1 -F rsnd/3 then, when the the USB device is present, it will be used; if it's disconnected sndiod switches to the on-board one. SIGHUP makes sndiod switch back to the alternate device, if present. I haven't tested this on FreeBSD yet. HTH, -- AlexandreReceived on Thu Sep 26 2019 - 22:13:24 CEST
