HomePod is amazing in sound quality (except its soundstage), but Siri is unable to understand long titles of classical albums (e.g. “Bach: Brandenburg Concertos – Orchestral Suites – Violin Concertos”). My current solution is: in iTunes on Mac, Airplay the album to Homepod. The good news is, when I use Siri to adjust the volume of HomePod, the iTunes’ volume level also changes (, while the sound from other apps on my Mac can output to other devices).
Update on Apr 20: On iOS, the “Music” app can also show what is being played and select albums for HomePod.
If you have other solutions, please kindly let me know. Thanks.
