The PCAOB released a new report on 2015 inspections of broker-dealer audits showing that deficiencies continue to occur at a high level. While results improved slightly from 2014, there is still much work to be done, including in independence compliance.

That SEC independence rule (i.e. strict prohibition on bookkeeping) has been around for many, many years. These independence violations (the PCAOB has been aggressively pursuing and sanctioning firms that flout the rule) came to light when the PCAOB expanded its jurisdiction to include broker-dealer audits as a result of the Dodd-Frank law.
