[alsa-devel] Pop noise on startup when headphones are plugged in (Dell XPS13 9333)

Hi,

I've recently found that commit a551d91473 ("ALSA: hda - Use regmap for command verb caches, too") is somehow causing a pop noise on startup when headphones are plugged in, but I couldn't figure out the exact cause. Was this observed on other systems (mine is a Dell XPS13 9333, Realtek ALC3661)? Does anyone have any idea of what the cause might be?

Regards, Gabriele
