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).

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.
Keep me posted.

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 .

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.

Did you have any more questions or need any additional help?

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?

Yes, casting works fine again. Thanks

Thanks for keeping us in the loop and glad to hear that everything is up and running now.
Since the issue is now resolved, I'll go ahead and lock this thread to keep our Community tidy. Feel free to start a new thread should you need help in the future.
Thanks for the help, Jeran!
