Following the update of my Allo Sparky dietpi (Non GUI) image from v156 to v157, I had an issue with Squeezelite.
The ALSA parameters (-a) had changed from v156 to v157 and this caused my USB connected Oppo BDP-105 to play distorted audio.
Removing the ALSA parameters (in /etc/systemd/system/squeezelite.service) solved the issue for me.
