Hello everyone!
Thanks to roland68 for the solution!
I am writing because, in my experience, this phenomenon only affects SPOTIFY playback.
I use VOLUMIO PI Zero and PI 4 and only cause fast playback when using SPOTIFY and only for USB “DAC” (SB wireless USB).
Is SPOTIFY allergic to USB DAC?
I reinstalled it several times, read a lot, tried a lot, but this is the only fair and good solution to the fast play phenomenon on my system.
VOLUMIO plays the radio well, local MP3. FLAC, etc. files, TIDAL, but Spotify is fast.
Thanks again for the correct solution!
