Hi, I hope this is the right place to ask . In the driver ( soc/codecs/wm8960.c ) there is a function that sets pll - the wm8960_set_pll() , line 1185 . On exit , the function turns on the pll clocking like this : /* Turn it on */ snd_soc_component_update_bits(component, WM8960_POWER2, 0x1, 0x1); msleep(250); snd_soc_component_update_bits(component, WM8960_CLOCK1, 0x1, 0x1); What is the reason for the 250 ms delay ? I did not find anything related in the chip datasheet . I found the delay very annoying in my app that generates an audible feedback to touchscreen events. Looks like it is safe to comment out the msleep() call , could there be any implications ? Best regards, Alex Shinkin
