core: Cast mp3 to Google Home Hub Fails

The problem

A script that has worked fine for a year suddenly fails when trying to cast a long MP3 file to Google Home Hub. Log states the following:

Additional information

This worked perfectly prior to 2022.6, and continued to work in 2022.6 although significantly more slowly. Now it doesn’t function at all

I’ve been debugging the issue together with @drakkather this afternoon, and in his case playing media works OK when using the Home Assistant media player but not with Google’s built-in media player.

It would be very helpful if you who also see this problem can verify that it works also for you, to do that follow these steps: 1. Prepare a local development environment for pychromecast (a working Python 3.8+ environment is needed):

cd <some_working_directory>
git clone https://github.com/home-assistant-libs/pychromecast pychromecast_test
cd pychromecast_test
python3 -m venv venv
source venv/bin/activate
export PYTHONPATH="."
pip3 install -r requirements.txt

Instead of python3, the executable may just be named python. The name of the venv activation script may differ if your environment is not Linux; if it’s some Windows version try source venv/Scripts/activate instead.

Try playing tts or other media using the already signed link shown in the error message (I’m using @drakkather’s link as example)

python3 examples/homeassistant_media_example.py --cast="<name of the cast device>" --show-debug --url "https://xxxxxxxx.duckdns.org:xxxx/local/presencia/04.mp3?authSig=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJmNTA1NzYwMTBmNTY0YTdlODUxYmVhNGU3NDBlNmY3NyIsInBhdGgiOiIvbG9jYWwvcHJlc2VuY2lhLzA0Lm1wMyIsInBhcmFtcyI6e30sImlhdCI6MTY1OTM0NDc2OSwiZXhwIjoxNjU5NDMxMTY5fQ.OM5p0F70XHf-v-dnbKhZTYDZmnv1paJUnSEfsNECciA"

You need to replace <name of the cast device> with the friendly name shown in the Google Home app, so for example: --cast="Living Room"
