'PlexSonosClient' object has no attribute '_timeout' #1490

Describe the Bug

Using the code snippet from the front page I can retrieve my sonos speaker and I was originally able to control it, but for some days whenever I try to execute a command I am facing the following error:

AttributeError: 'PlexSonosClient' object has no attribute '_timeout'

Code Snippets

from plexapi.myplex import MyPlexAccount
from plexapi.server import PlexServer

account = MyPlexAccount('<EMAIL>', '<PASSWORD>')
plex = account.resource('<PLEXINSTANCE>').connect()

# List available speakers/groups
for speaker in account.sonos_speakers():
    print(speaker.title)
    speaker.stop()

Expected Behavior

Stop playing music on (any) sonos speaker.

Additional Context

Tested this on a raspberry (with python 3.12.3) and from another ubuntu (python 3.11.11). Same error on all instances.
