Fixes an onboard clock detection problem of the PRO versions

Joerg Schambacher · popcornmix · commit cc33d2788617 · 2021-06-14T12:44:01.000+01:00
Increasing the sleep time after clock selection to 3-4ms
allows the correct detection of all combinations of DAC+ Pro
and DAC+ADC Pro sound cards and the various PI revisions.
