Research direction

Start with the attached sendspin.log around 11:15:01 and reproduce the issue through sendspin-cli using the listed WAV formats. Compare playback of 44.1 kHz 16-bit and 24-bit-or-higher files on the Raspberry Pi 4 with the Fosi Audio ZD3. Done means the affected tracks play without static noise.

Description

Hi,

I currently encounter a very loud static noise at the end of some tracks I play via Music Assistant.

I already tried setting to pcm instead of flac and using different khz and bitrates, but the issue persists.
Disabling and messing with the limiter and dynamic normalizer Music Assistant uses didn't fix the problem.

File encodings that produce the noise (as far as I have seen):

  • 44100 kHz 16 bit WAV -> Very loud, short, static noise at the end of each track
  • 44100 kHz >= 24 bit WAV -> Only very loud static noise the whole track

Hardware:

  • Raspberry Pi 4 running via 5G WiFi with sendspin-cli installed
  • Fosi Audio ZD3 USB DAC
  • Raspberry Pi 5 running HomeAssistant with the Music Assistant Add-On via Ethernet

Am I missing a dependency?

I attached the debug log. Starting 11:15:01 the static noise appeared

sendspin.log
