… various ways to announce messages in my house. A nice example is the "washing is done" automation, which first plays a TTS message "Washing is done!" on my Google Home Hub, and then shows an image of a Washing machine for the next 15mins to make sure you can see what was said if you miss the voice announcement. Few days ago, casting the image broke: it simply wouldn't show anymore and logs indicated something like `2021-04-27 13:29:37 ERROR (Thread-16) [homeassistant.components.cast.media_player] Failed to cast media https://*redacted*/local/icons/wasmachine-green.png from internal_url …

I'm gonna be brutally honest with you. If you want decent multiroom audio, like Sonos, get rid of your Google mini speakers. Sure, you can use the Cast integration, pre-define groups in Home app and use Spotcast (custom integration that allows to play Spotify over Chromecast). But it has issues (like dropped Chromecast speakers, Spotify API changing and no option for on the fly speaker changing). I have 6 of them and only use them for voice commands and notifications (after having used it like mentioned above and going crazy at a point). So get a couple of Raspberry Pi's and install …

… different option to Sonos, which I've never used, I'd suggest Wiim. I've got 4 setup throughout the house. They work well and you can use whatever dumb speakers you have with them. I've also got GoogleHome Nest Audios mixed in which work when they want to. These speakers are mainly used for voice control of HA, for the rare occasion an automation isn't handling everything.

With Google devices, when you cast any kind of notification, it plays that annoying casting sound BEFORE your notification plays. And it lags like crazy. I have exactly one Alexa device in my office and casting notifications to it is so much better. Quick, no lag and no additional s\*it that it plays. It also doesnt show a "Playing screen" and stays on the time, which is what I like. &#x200B; P.S. Integrating both in HA is a piece of cake.

Oh boy. I really don't feel like typing it out again, but... - I have 3 Nest Audios, 4 Nest Minis, and 4 Home Minis - Speaker pairs constantly unpair and need to be factory reset - They constantly refuse to acknowledge commands - They just... stop. No lights, no touch response, nothing - They intermittently claim to have lost WiFi, despite all other IoT devices around them working. This has persisted through half a dozen routers, three ISPs, WiFi 4, 5, and 6, Multicast snooping enabled, disabled, subnet routing enabled, disabled, DNS on default, Google DNS, DNSSEC enabled/disabled, etc. etc. …

The problem Starting a few weeks ago or so regular casting of SiriusXM to any nest speaker or google device fails with error code 1001 when trying to cast from phone or computer. This can be fixed by disabling the Google Cast integration on Home assistant. If i start the casting and then re-enable the cast integration everything seems to work fine and I can still control the devices. After stoping casting, while the integration is still running, I am unable to start a cast again from phone or computer. This is fixed by disabling the integration again. This is only occuring with SiriusXM. …

The problem Speakers are not shown as speakers in HomeKit, but (in my case) as 4 switches. If I add the speaker direct to HomeKit (without HomeAssistant over the AirPlay2 functionality), then the speaker could be added as speaker as it should. ### What version of Home Assistant Core has the issue? core-2024.2.0 ### What was the last working version of Home Assistant Core? _No response_ ### What type of installation are you running?

The problem When I attempt to cast a dashboard to my Google Nest Hub the device tries to connect, but doesn't accomplish at displaying the dashboard. When reviewing the logging I noticed the following entry: line 973, in send_app_message raise UnsupportedNamespace( ... ... ) pychromecast.error.UnsupportedNamespace: Namespace urn:x-cast:com.nabucasa.hast is not supported by current app. Supported are urn:x-cast:com.google.cast.sse, urn:x-cast:com.google.cast.cac I'm on the latest version of the core, so this is not the old issue that was resolved some versions ago. ### What version of Home …
