Sudden loud sound when resuming playback in e.g. Spotify

[thinslice]

Expected behavior: Resuming playback (by starting the playback of a different song in Spotify) doesn't cause any additional sound other than the song itself.

Actual behavior: There is a loud sound (the old contents of the audio buffer as I hear) played back when this happens.

Steps: Enable Wavelet. Start Spotify. Start a song and then stop at a louder part. Wait a few seconds, then press the "next song" button or start an entirely different song.

Wavelet settings: Legacy mode: yes. Buffer size: 8192 samples AutoEq: on Limiter: on Channel balance: on

Android: I am using Android 10 (MIUI).

Notes: The issue is quite annoying, I am scared to death almost every time I resume playback. It consistently happens with Wavelet enabled and doesn't with Wavelet disabled.

How about clearing the buffer (writing all 0's) when the playback stops or the audio device is suspended? I had the same phenomenon on my computer running Linux and fixed it by disabling the "suspend on idle" feature. More info: https://wiki.archlinux.org/title/PulseAudio/Troubleshooting

Could you report if the issue is resolved in the latest update?

Sorry for the slow reply. I tried with the latest version now (Version 23.09, released on Sep 27, 2023). Maybe it's a little better now but it could be just placebo. I can still consistently reproduce that a split second of the last played song is audible when I start another track after a bit of a silence. If Wavelet is turned off, it doesn't happen. I am using Android 10 (MIUI), I'll add this to the original post.
