I have a Dell Inspiron 15 7000 (7590) with a GTX 1650.
I use PRIME, and the advanced power management documented here:
This setup works well: the Nvidia card remains in a low-power state except when required.
However, I experience audio glitches (buffer underruns) in pipewire and/or pulseaudio. These glitches disappear completely if I change the Powermizer setting to “Prefer Maximum Performance”, so the card remains at performance level 3.
I suspect the card is slow to release some lock or respond to some message on a shared bus due to the low power state. Is this a known problem?
