Streaming currently playing audio to HomePod causes track to restart from the beginning

When playing audio using Cloudreve for iOS, initiating AirPlay to a HomePod causes the currently playing track to restart from the beginning instead of continuing from the current playback position.

Start by reproducing the issue in the Cloudreve iOS/iPadOS client with audio playing, then initiate AirPlay to a HomePod and observe the playback position. No source files or tests are named; done means the track continues from its current position instead of restarting when streaming begins.
