Since about a week ago, whenever we turn the TV off and on again, the Chromecast does not have audio. Restarting the Chromecast fixes the issue, but this is quickly becoming extremely bothersome.
Some further observations:
- the problem started a couple of days ago. My partner insists it was sporadic at first, from my experience it has been a hard break (never dropped before, now always drops sound whenever the TV is turned off and on again).
- audio is broken across the entire chromecast, not a specific app. UI feedback is also gone.
- audio reliably works after the chromecast is restarted.
- audio is not muted nor is the volume set to zero.
- the chromecast is directly connected to the TV. There are no other devices (neither inputs nor outputs) connected to the TV.
- resetting the chromecast to factory defaults had no effect.
- switching the HDMI port on the TV has no effect.
- restarting the TV has no effect (in fact, it seems to cause the issue)
- switching sound inputs/outputs on the TV has no effect.
On a side note, Google refers to this forum for support on the Chromecast. It feels like this is the wrong forum, also considering the labels I am forced to choose from (OS, cast source) have no bearing on the Chromecast dongle. If there is a better forum for support, please let me know, and I'll take my question there. If there isn't, why is the support forum set up this way. I would think Google can afford to set up a tailored support forum for such a popular device?

We have the same issue!! LG TV and have tried everything to fix!! We have even gotten a new chromecast and it still happens. Sometimes when the tv is turned off and back on the chromecast sound will not work. Only a restart of the chromecast can fix it. It MUST be a bad software update they pushed out... Please Fix This!!!!
My new Chromecast (purchased a few weeks ago) hasn't lost Audio yet, may be a different issue to you guys but used to happen changing apps or skipping forward in an ep sometimes.
The new one did a system upgrade straight away before use. No choice not to. Probably worth people trying a system reset etc and setting it up in a normal HDMI port (I did it on my PC monitor just out of convenience).
Not sure if any help.
You could always test a firestick 4k in the meantime, hard to get much support from Google, or even to acknowledge the issue here. Perhaps there aren't any dev's present etc. All of a sudden a lot of my smart home plugs and lights are showing offline in the Home App, pretty flakey. A router/phone reboot didn't help, trying to reconnect connect smart home I guess, all this stuff is more effor than it's worth half the time.
after several weeks i got the following response from google, atleast it appears to be a known issue and may get rectified in a future update
Thanks for reaching out to the Google Nest Customer Care Team.
This is XXXXX, from the Chromecast Support Team. I see you have concerns about your device. Apologies for the inconvenience that this has caused you. Let me help you out.
Please try to switch the Chromecast to a different HDMI port and observe if there are any improvements.
If the same issue would persist, please proceed with performing a factory reset on the Chromecast. This way the device could refresh the software and realign with the newest updates. In some cases when the Chromecast could not update properly, some things would be out of sync.
This is actually a known issue. Our product engineers are working on getting a fix for all of Chromecast devices that are affected. If you have already done a factory reset, please perform the reset one more time so the device can align with the latest update of the firmware.
My problem seems to have fixed itself now. Problem with no sound started out as constant, then started happening about half the time. Now the sound has been coming on okay for several days in a row.
I have 3 4k Chromecasts connected to a TCL 5 series, model 55R617, TCL 5 series model 43S525, and TCL 5 series model 43S517.
All three TVs are connected to a Sonos Beam Gen 1 soundbar using HDMI ARC ports and HDMI CEC control.
Mine has been working since I updated to the latest version a few days ago.
Hopefully they fixed it. 🤞
If so, it took a month and I did not see any official acknowledgement that this was a common known issue, this is frustrating.
[Also, weirdly, the menu sound effects that play in the OS sound differently than before and like they are better quality?]
I had the same problem. I think the problem is the power supply. I was using my old Chromecast plug, when I put the new one in it stopped having problems.
Possibly the firmware or software updates have created some startup processes that take more power. Maybe another solution is to start the Chromecast after your TV is already turned on.
I'm just using a USB C pd phone charger. Agree can't use tv Power but my old ccwgtv did it with the same charger.
Would recommend factory reset and setting it up on a non HDMI arc port. sounds like they haven't found the issue to be honest.
FFS I spoke too soon. My new ccwgtv lost sound finally, when skipping forward or episodes on Disney+.
Quickest fix is to toggle the soundbar sound modes.
