Comment 2 emersion 2019-07-16 14:00:51 UTC
Seems like a Chamelium bug. Chamelium logs:

2018-05-05 17:55:48,955 ERROR Failed to stop capturing audio: No audio data was captured. Perhaps this in
put is not plugged ?
Comment 3 emersion 2019-07-16 14:02:29 UTC
Ah, and this happens because we don't receive any data from the Chamelium via the streaming server. read hits the 5sec timeout.
Comment 4 emersion 2019-08-16 12:56:40 UTC
This issue is specific to fi-kbl-7500u. It's hit every week.

User impact: worst case scenario, no audio via HDMI.
