No more sound with Chromecast v2

Plex Players Streaming Devices

Server Version#: 1.25.2.5319
Player Version#: Android 8.28.0.30077

Hello,

I used to use my android phone to stream videos from plex to my chromecast on a Sony KDL40EX500 using its integrated speakers.
Then all of a sudden, wednesday 05/01 afternoon, in the middle of my daughter watching “Frozen”, my TV showed a message “Surround sound activated” and sound was gone.
Since then, every video that has more than two sound channels doesn’t play sound.
I am 100% sure it worked before, entire seasons of shows I watched on the chromecast doesn’t play sound any more.

Do you have any idea about how to fix this ?

I had three, but none of them worked :

  • Configure my TV to limit sound to stereo. I tried to go into my TV settings, but the “Option” or “Menu” button does nothing when I am on the HDMI input.
  • I tried several options on the android app, like setting “Max level H264” to 2.0, but nothing worked.
  • Change the chromecast profile on the server to tell plex to transcode down to stereo. But If I read Chromecast.xml well (and in the logs it says that Chromecast profile is used), channels are already limited to two. Nevertheless, the dashboard of the web app says that AC3 5.1 is sent to the chromecast.

      <Limitations>
        <UpperBound name="audio.channels" value="2" />
      </Limitations>
    </VideoAudioCodec>
  </CodecProfiles>
</Client>

Any help would be very appreciated.
Many thanks.

Self replying : I solved it by forcing chromecast to stereo mode in google home app.
Still doesn’t know why plex was streaming 5.1 using this profile, but anyway it works.
