Cannot find any chromecast device?

[room-homage]

Where do I start to debug such issue?

[philippe44]

it's usually because AirConnect is not on the same network/subnet as your CCs

[squallstar]

@philippe44 I have the same issue with a Apple Macbook Pro M2 Pro on Sonoma 14.0 (public beta).

I've got plenty of Chromecast compatible devices in my network and this is the only output I get from the script:

[philippe44]

Old GenX speaking here 😄, it's not a script but a plain C/C++ compiled application. More seriously, you're using the version for UPnP devices, not the one for CC players.

[squallstar]

@philippe44 thanks, sorry about that I tried with the CC version and it's correctly discovering compatible devices now. However, a few seconds after I cast audio to any of the devices I get this error and the application exits:

Ah, this one ... I've never been able to figure out. It only happens on Mac and arm64 so I can't investigate. I think the x86 version works fine with Rosetta

[squallstar]

@philippe44 the issue is replicable with the x86 version as well on macOS Sonoma, see:
