Radio skill audio drops out

I have had frequent experiences with the Mycroft Radio skill wherein I’ll be streaming a station fine, then ask Mycroft to change the station, and suddenly audio stops. The screen updates to show a new station but there is no longer any audio. When I try to switch to a new skill (ex: “Hey Mycroft, whats the weather?”) the screen changes to show me the weather but I don’t get any audio. Additionally, the screen stays on the weather display and never returns to the radio.

I’m happy to provide any files off the system that are helpful in debugging this scenario.

The next time this happens, if you could grab some logs like so and post them or send them along to us that would be very helpful.

journalctl --since=9:00 -u 'dinkum*' > logs.txt

There is a bit more info here.

Here is the journal output, messages of note are on the 11th. I had to rename the file to jpeg but should be accessible if you change it back to .txt. I see errors about the codec vorb. The forum won’t let me upload a text, Here is more of the file mycroft-radio-failure - Pastebin.com

Is it happening with a particular station or channel/genre? I can’t see the station URL that it is trying to open in these snippets. That may be good to know as we look into this. If you look earlier in the logs (assuming it is still there), then it should show the radio skill trying to open the stream.

If/when it happens again, please make note of the channel/genre, the station name, and, if you can, the actual URL of the station.

OK, some more details. I was streaming WUVT on the College channel for at least 10 minutes and then audio stopped playing. I issues a command to change the station which appeared to be recognized since the display updated to another station, but no audio played. Here is a link to the logs around the time of the drop.

Looks like the URL is http://engine.wuvt.vt.edu:8000/wuvt.ogg
