Chromecast audio not detected

stevend — Fri, 18 Feb 2022 08:20:55 GMT

Hello,

I have a Chromecast audio connected to my network.

I can cast without any issue from my phone, however on my laptop the Chromecast is not available.

I followed the steps listed in https://support.google.com/chromecast/answer/3249268 -> not solved.

I am running Windows10, with no extra anti virus (only Windows Defender).

Any ideas?

Hi stevend,

Sorry for the late response, but thanks for being a step ahead of us. Please try the additional steps listed below and let me know how it goes:

Reboot your laptop and your router.
There are cases (mostly in Windows) wherein the Chromecast device fails to work after the antivirus finished an update. If this happens, please call your antivirus provider.
Uninstall and reinstall the Google Chrome browser.
Download Chrome Canary.

Keep me posted.

Thanks,

Jennifer

Hello Jennifer,

Seems this issues is caused by Windows Defender.

If I install Avast Antivirus , which disables Windows Defender, Chrome detects the Chromecast device just fine and streaming is possible.

When I uninstall Avast (I want to get rid of it), the Chromecast device is no longer detected by Chrome.

So it seems Defender is blocking a port, but I can't seem to find where it is configured, or which port is being blocked .

Regards

Hey there stevend,

Do you have Windows Defender or Firewall blocking outbound web ports? Usually, the Chromecast should work in a basic Windows configuration. I would also double-check you don't have AP Isolation and IGMP snooping enabled on the network, as that would cause some connection issues as well.

Also, this thread about Chromecast on Windows 10 on the Microsoft forums may help out here as well.

Best regards,

Jeran

Hello, after I reinstalled Avast, and then removed it again, it kept working. No idea why this didn't work before.

Hey there stevend,

That is interesting! I'm not too sure why it didn't work for you before as well. Does that mean everything is up-and-running again?

Best regards,

Jeran
