No compatible audio format found

[Skostrub]

USB Audio card installed.
Works with Audio station.

Service VoiceRSS configured.
Web audio works (in desktop brouser)
Default speaker (should be USB card) while attemting to run "Say" command brings:

[WARN ] [core.voice.internal.VoiceManagerImpl] - No compatible audio format found for TTS 'voicerss' and sink 'javasound'

Not sure whether it should be addressed here, but since it is relevant only to OH2 running on Synology I will post it here.

Have you read the docu:
http://docs.openhab.org/configuration/multimedia.html

To check, which audio sinks are available, you can use the console:
openhab> smarthome:audio sinks

[Skostrub]

btw on Synology DS213J
I cannot connet to console.
If I run ssh -p 8101 openhab@localhost
it closes due to timeout. So I do not see password request.
It might be slow system performance when ssl key is generated.
but after several attempts it always disconnects after timeout.

Start.sh scripts for OH2 does not work. So I tried to stop the service from package manager.
Then run client app from /var/packages/openHAB2/target/runtime/bin.

This tricky way passed me to OH 2console, but
openhab> smarthome:audio sinks - command unrecognized.

I try this on the diskstation:

DS3615xs> ssh -p 8101 openhab@localhost

Are you sure you want to continue connecting (yes/no)? yes
