Subject: [PATCH] Fix UI hanging when toggling audio output enable/disable

Make audio start asynchronous to prevent blocking the RPC response.
Previously, enabling audio would block until ALSA initialization completed,
which can take 30-60 seconds for HDMI audio due to TC358743 hardware.

This also fixes the -1 decode errors that occurred when packets arrived
during the synchronous restart window.

Matches the existing async pattern used in SetAudioOutputSource().
