Version: 51.0.2704.79
OS: 8172.47.0

Device: Guado dogfood

Last week I received an update to the latest beta version... after that, audio through the analog audio connector is gone*. I filed a feedback report last Monday with the system info, but basically under audio_diagnostics there is nothing recognized as an output device.

I just changed the channel to stable and unsurprisingly the behavior is the same (same beta and stable version, oh well)

Then I switched to dev channel (52.0.2743.32 - 8350.21.1) and surprise: audio devices are back! (and there's audio)

(*) I don't know if there was audio through HDMI, but audio_diagnostics didn't detect any device, and there are 4 devices listed with the dev channel.

(I don't know if this is fixed and waiting to be released, but saying P0 just in case)
