missing attack of sound with playbin after seek to beginning

I'm developing a software that plays sound using gstreamer playbin (in
python, with qt).
When playing sounds that have a fast attack (such as bass drum samples, i
can provide examples if needed), i have issues in some situations:
- on my development laptop in debian testing (debian 12), with gstreamer
1.22, pipewire, when I load the sound and play it the first time, i get the
correct attack, but then when seeking to 0 and playing again, the attack of
the sound is "eaten", which in some cases can deeply alter the audio
rendering (on a bass drum sound with a short attack, the attack is really
missing, it sounds really different)
- on the same laptop, in a virtualbox VM in debian stable (debian 11),
with gstreamer 1.18, pulseaudio, the issue does not occur
I tried many things to solve that, like playing with seek flags, even
trying introducing small delays between operations, and at this point i'm
really lacking ideas, so any help, suggestions would be appreciated.
