Marco, I see your issue with discord, there is a delay in the output when tsched=1.
Sometime the sound get 'robotic', or there is a pre-echo and an echo, sometime the issue vanish when I play around with other application that capture or playback audio. This remind me a weird audio issue I had with my previous system (old core 2) in some steam game in the past, not sure if it's a kernel issue.
