On the Legion Go S Z1 Extreme with native SteamOS, when it is connected through a hub/dock via HDMI output, the system automatically detects the external monitor, but the audio output does not automatically switch to the monitor and instead has to be changed manually.

Steps for reproducing this issue:

1. Connect a USB-C hub/dock to the device.
2. Connect the hub/dock to an external monitor/TV via HDMI.
3. The audio comes from the device’s speakers and not from the monitor/TV.
