No audio from Chromecast when casting desktop

[Mtlhd1011]

Sorry, this is a repost because my initial post was closed. I was out on vacation out of the country and then sick, so I missed the replies. I am having issues casting my Desktop's audio and video to my chromecast successfully. I can click the cast to button in the chrome browser, then I select cast my desktop, and then I select my chromecast device. When I do this the video successfully casts, however I get no audio to my chromecast device no matter what I am doing on my PC. I have had a similar problem like this before with not being able to cast my desktop successfully, and I was told to change something in the Chrome flags and it solved my issue. I have since upgraded and changed my computer, so I am sure whatever setting that was may have been set back to default. Has any one else experienced this and has an answer on how to fix it? I have tried editing several chrome options and factory resetting my chromecast. I am running the latest version of chrome, latest chromecast version, latest google home app version and the latest windows 10 version. Any help would be greatly appreciated!

As suggested in the previous post before it was closed I checked my audio outputs on windows 10. There is no other selection available other than speakers. I also downloaded and installed google canary. This has the exact same issue as regular chrome.

Hey there Mtlhd1011,

I apologize about the late response on this thread, thank you for being patient! Were you able to fix that audio issue? If not, I'd be happy to help out, as I can imagine this issue is quite frustrating. You mentioned that you were able to resolve this by changing a flag in your Google Chrome settings? This tag may be chrome://flags/#try-supported-channel-layouts if you are on Windows. Enable that flag and let me know if that resolves this issue.

I look forward to your response, and if you have any other questions or concerns for me, please let me know!

Best regards,
Jeran

Hello Jeran,

No I have not fixed it, I will try your suggestion and see if it works. Thank you!

Hey there Mtlhd1011,

Did you have the chance to give those Chrome Settings a try, or did you have any more questions or need any additional help?

Hello Jeran. That flag does not seem to exist in my version of chrome. What should I try next?

[Jeran]

Hey Mtlhd1011,

No problem, try going back into the flags, and disable "Allow all sites to initiate mirroring":

Here is how to disable that particular flag:

1. On the address bar, type chrome://flags/.
2. Look for Allow all sites to initiate mirroring and set to Disable.
3. Click Save.

Give that a try, and let me know if that works.

Best regards,

Jeran

Hi Jeran,

I found that flag and disabled it. Unfortunately, it did not change anything. There is still no sound when casting to the chromecast from my PC.

[Jeran]

Hiya Mtlhd1011,

That is strange, we can try a couple of other things to see if they help resolve this. First, I would go into your Windows 10 Sound Settings and change your default sound device until you find one that plays sound when casting. If that doesn't resolve the issue, disconnect any external receiver, soundbar, or speaker from your TV and see if there is any volume after that.

I hope that helps, let me know if the problem persists.

Best regards,

Jeran

Hi Jeran, I tried what you suggested, still no success.

[Jeran]

Hey there Mtlhd1011,

That is very strange. At this point, you may need to reach out to Chromecast Support, as they would have more tools than we would here on the forum. You would just need to get past the prompt, and you should be able to speak with them via phone call or online chat.

I'm sorry that we weren't able to resolve this issue, but if you had any other questions or concerns, I'd be happy to address them.

Best regards,

Jeran

Hello,

I've tried to go that route before and never got assistance but I'll try again. I haven't been able to reach out because of the holiday weekend. I'll see if I can get a new case going this week. 

[Jeran]

Hey there Mtlhd1011,

No problem at all! Did you want me to leave the thread open to be safe, or should we go ahead and lock it?

Best regards,

Jeran

[Mtlhd1011]

If we can leave it open, that would be great. I'd be more than happy to share the resolution here when we get to one. 

[Jeran]

Hiya Mtlhd1011,

Sounds good, I'll go ahead and leave this open for a while longer. We look forward to hearing back from you!

Best regards,

I found the fix in an old email! I had to enable this chrome flag and it fixed it!

connect to cast devices on all IP addresses
