Try setting the playback option in the device toolbar to "Microsoft Sound Mapper" and see if that works.

If you Save the Audacity Project, then the time shift will be saved.
For "exporting" audio, the result may vary depending on what exactly you are doing.

Sounds pretty good

Audacity uses Lame for MP3 export. Audacity uses FFmpeg for M4A export. Don't use the dot (".") character in file names. If you enter a file name as (for example) Ep 01 and then export as an MP3 file, then Audacity will automatically add the .mp3 file extension so that the name becomes: Ep...
